Sportscar makers at the pointy end of class flout what appear to be inevitable business decisions the same way their offerings flout what appear to be inevitable physical limitations. Questions we’ve asked for years include: How long until Ferrari builds an SUV? (Next year.) How long until Chevrolet reveals a mid-engined Corvette? (Soon?) And how long until Lamborghini must perform hybridised open heart surgery on its nonpareil V12? According to Motor Authority, as part of an interview with Lamborghini R&D honcho Maurizio Reggiani at the Detroit Auto Show, the answer to that last question is likely with the next generation.

Reggiani told MA that the next-gen Aventador will definitely come with a V12. After that, the man who makes the bulls said “we must decide what will be the future of the super sportscar in terms of electric contribution,” the principle issue of that contribution not being performance, but weight and power delivery. The 4,085-pound Aventador makes scales weep, explaining why Reggiani is so grave about weight implications that even a dual-clutch transmission – a seeming shoo-in for the next-gen car – won’t get a pass until it justifies its extra heft over the present, hoary, single-clutch gearbox.

Carbon fiber already forms the Aventador’s tub, so engineers in Sant’ Agata can’t evaporate hundreds of pounds with that conversion. Lamborghini’s been working on the new car’s platform a for more than a year, no doubt with batteries in mind, yet stuffing a load of Triple As into the chassis could turn a battleship into a dreadnought. That formula works for Bugatti, but won’t serve Lamborghini nor its clientele. Reggiani isn’t opposed to some sort of electric assistance when the next-gen car bows in 2020 or 2021, and at the Frankfurt Motor Show last year said he sees plug-in hybrid tech as the next step, but we won’t be surprised if the V12 song remains the naturally-aspirated same at launch.

Still, the question of electrification – and turbocharging – remains one of “When?” There’s so much writing on the wall that the writing is the wall: two years ago, Reggiani admitted that turbos will get bolted on “sooner or later,” as did Lamborghini’s commercial officer Federico Foschini last year, the Urus will dial up a hybrid powertrain soon, reports declare the next-gen Huracán will go hybrid in 2022, and Euro 6 emissions aren’t getting less stringent.

No matter how the coming flagship makes its power, expect more of everything. Reggiani told MA that the Lamborghini Active Aerodynamics system used on the Huracán Performante remains “a big potential that we have in our pocket,” but we could see that on a coming Aventador Performante. And there are always those carbon fiber connecting rods waiting for just the right use case.

Zunum Aero, a fledgling transportation startup that promises to “take aviation into the future” using small hybrid-electric aircraft and regional airports, has provided more details about how it plans to achieve its goal.

By way of a quick recap, we first reported on Zunum Aero back in April when it launched out of stealth with financial backing from Boeing and JetBlue’s venture capital arms — HorizonX and JetBlue Ventures, respectively.

The company revealed at the time that it was building 10- to 50-seat aircraft that will tap thousands of quieter regional airports around the U.S. to transport people up to 700 miles. Zunum Aero aims to put this service into effect by the early 2020s, with plans to increase the flying range to 1,000 miles within a decade.

The problem Zunum Aero is looking to fix is this: More than 95 percent of all U.S. air traffic passes through just 2 percent of the country’s 5,000 airports. Zunum Aero wants to harness all those underused local airports to build an electric aircraft network that promises not only lower emissions but provide a 40 percent decrease in door-to-door travel time. Additionally, the company said that due to lower in-house operating costs, it will be able to offer 80 percent cheaper fares.

While Zunum Aero’s original proposition was alluring, it didn’t offer much in the way of details. Today, the Kirkland, Washington-based startup is offering a glimpse into what it has in store.

Baby steps

Zunum Aero initially plans to build a 12-seater hybrid-electric aircraft that travels at a maximum cruising speed of 340 miles per hour. This aircraft is targeted for a 2022 launch. So, basically, the first Zunum Aero vehicle will be capable of traveling for around two hours — it won’t get you from New York to San Francisco, but it could get you from Boston to Washington, D.C. The company predicts that such a flight could cost as little as $ 140 one-way, with a 2hr 30m door-to-door journey, factoring in a number of regional airports.

The company created this computer simulation of how its service would work when it’s up and running.


Digging into the details, the company is promising a direct cost of 9 cents per mile for each seat, which works out to around $ 260 per hour for the entire aircraft.

The company also provided these additional specifications:

  • Quiet electric propulsors with variable pitch fans, enabling a 40 percent reduction in runway needs, 75 percent drop in community noise, and fine thrust control
  • Wing-integrated batteries that enable tailoring of onboard battery capacity and quick swap or recharge at airports
  • An optimization and control platform that provides real-time flight energy optimization, power management, fault detection, and recovery

“This aircraft is going to transform how we live and work,” claimed Zunum Aero founder and chief engineer Matt Knapp. “We’ve pushed ourselves to challenge conventional wisdom and the limits of engineering to deliver an aircraft of which we are extremely proud — one that offers efficiency and performance without compromise.”

Flying cars and other innovations in air transport have emerged as something of a trend in the entrepreneurial and VC realm. Last month, German aviation startup Lilium raised $ 90 million to build a network of on-demand flying taxis, and Slovakia-based AeroMobil recently raised fresh funds to bring flying cars to Asia.

Elsewhere, Massachusetts-based Terrafugia has been working on prototypes of “roadable” aircraft for more than a decade, while Google cofounder Larry Page is backing two aviation startups. Kitty Hawk debuted its ultralight personal aircraft earlier this year, and Page founded Zee back in 2010 to build a “small, all-electric plane that could take off and land vertically,” according to a Bloomberg report.

Zunum Aero said that it’s planning to open a second development center in the Chicago area and plans to commence ground tests ahead of the first test flights sometime in 2019.

While the machine boasts a comprehensive suite of active aerodynamic technology from adjustable spoilers to opening vents, the right and left sides of the Project One can’t operate independently of each other.

As you may remember, the Lamborghini Huracán Performante‘s party pieces are vents that adjust the amount of downforce applied to either the left or right side. This helps keep the car level in corners, and it likely contributed to the Lambo’s wickedly fast Nürburgring lap time. The astonishing Project One will not take advantage of a similar system.

Moers told us he didn’t see an advantage to such a variable system. He feels that having downforce is vital right from the moment of turn-in, and adjusting downforce left and right can’t be done quickly enough to make a difference at corner entry. And there’s no way to predictively adjust aero to prepare for a corner, at least not at this point in time. That being said, Lamborghini certainly sees merit and has said there are benefits in high-speed corners and we agree that it makes a difference.

Mercedes-AMG Project One powertrain

According to Moers, 1,000-horsepower Formula 1 V6 hybrid powertrain wasn’t particularly difficult to make durable and reliable enough for daily driving on the streets. He said that the criteria from racing wasn’t too far off. One of the primary difficulties was getting the idle down from around 4,000 rpm to a more livable 1,000 rpm. Accessories like air conditioning, which usually require belt-driven compressors from the engine, were taken care of by simply powering them with electricity, something the hybrid will have plenty of.

We also gather that Mercedes will take the car to the ‘Ring to set a lap time. Unfortunately, Moers wouldn’t give us a target time the company is shooting for. After all, there are still some things to fine tune and prepare before the company starts delivering cars to customers in 2019.

Deciding who gets a Project One is another of the things Mercedes-AMG is still working on. Despite a cost of over $ 2.5 million, demand is impressively high. Moers told us that about 3-4 times as many people asking to buy one as the total allotment of 275 cars. So if you’re not already in line, well, it’s probably not gonna happen.

Polestar as we know it is coming to an end. Volvo’s performance division will soon be spun off into its own brand, and with that change comes electrification. That’s not necessarily a bad thing, as cars like the Acura NSX and Porsche Panamera Turbo S E-Hybrid prove that electric motors can enhance, not detract from a car’s performance. As things draw to a close with Polestar’s current models, the Volvo S60 sedan and V60 wagon, the automaker has added a limited edition model with a new carbon fiber aero package.

Polestar says the package increases downforce by 30 percent over regular models. The parts were developed along with Cyan Racing, Polestar’s racing partner and the team currently fighting for the title in the World Touring Car Championship with a WTCC-prepped S60. Lots of companies offer carbon fiber appearance packages, but the fact that these are race derived and functional set the Polestar twins apart.

The limited run of 1,500 models will include a carbon fiber front splitter, side skirts and rear spoiler. It doesn’t sound like much, but it doesn’t take much to drastically change a car’s aero. Non-aero additions include gloss-black wheel accents, carbon fiber door mirror caps and a new exterior color. Each model will have the serial number on the door sill plate.

The rest remains the same S60 and V60 Polestar we know and love. That means a twincharged 2.0-liter inline four making 362 horsepower and 347 lb-ft of torque. Power is sent to all four wheels through an eight-speed automatic. The S60 can hit 60 miles per hour in just 4.4 seconds (4.5 for the V60) and has a top speed of 155 mph. Other Polestar upgrades include Öhlins shock absorbers and six-piston Brembo brakes.

It was just an ordering shorthand, a Regular Production Option, a box to check so the line worker knows what to bolt onto the next car. Some RPO codes have acquired a mythos, becoming marketing terms unto themselves. ZR1, Z71, Z28. But the 1LE, despite sounding like a base trim level on a Cruze, is something special.

Racing plays a large part in the 1LE’s beginnings. In the mid-1980s, Camaros were running in a Canadian showroom stock class called Player’s Challenge. The hardware GM was screwing on the cars from the factory wouldn’t cut it, so the engineers devised a brake and handing package and then picked an RPO code to sell it under. GM wasn’t marketing the car, probably so as not to draw competitor’s attention to the enhancements, but by the fifth generation GM realized the 1LE resonated with the Camaro crowd, and the Zeta 1LE (a handling package on SS models full of trickle-down ZL1 bits) helped bring the RPO code out of obscurity.

Don’t forget that the 1LE badge is tacked onto the back of another legend, ZL1. That code originally snuck pure racing big-blocks into unassuming 1970 Camaros to homologate some Can-Am cars. Heady stuff. The new ZL1, now in its second generation as a supercharged super-Camaro, is a combination of show and go – and it actually handles, too. (If the ZL1 1LE is too much, you can also spec 2017+ V6 and V8s with a track package sharing the 1LE code.)

2018 Chevrolet Camaro ZL1 1LE

Much of what Chevrolet changed is in order to leverage some truly impressive rubber. The last-generation Z/28, a good reference point for the new 1LE, used some very sticky Pirelli Trofeo Rs, barely street legal and grippy like hot tar. Chevy switched to Goodyear for the 1LE’s tires, steamrollers at P305/30ZR19 and P32530ZR19. The Eagle F1 Supercar 3Rs, thanks to an exotic compound and more width in the rear (the Z/28 wore 305/30s all around), trounce the Trofeo Rs. These are DOT-legal tires, although on the hairy fringe of sanity, and a lot of the reason the 1LE can corner at 1.10 G.

That’s right. One-point-one. That’s a tenth of a G increase over the Z/28, and would best a 991 GT3 RS. Who said pony cars can’t handle?

A lot of that is due to the control provided by the Multimatic DSSV (Dynamic Suspension, Spool Valve) shocks and the way they’re mounted to the Camaro. They’re similar in basic operation to what the Zeta Z/28 wore but recalibrated for this car’s weight and the tires. The rears are essentially identical to Z/28 units, but also recalibrated. Up front, the struts get aluminum bodies instead of steel, topped by a two-position camber plate (-1.5 for the street, -3.0 for the track). The rubber isolator was ditched, so these are hard-mounted to the shock towers – more rigidity and precise control, and it saved a bit of weight. The spring perch is adjustable so you can change the ride height up or down 10 mm. There’s more adjustability in the rear stabilizer bar, with a neutral position as well as a +10 percent and -10 percent stiffness position. The rear cradle is also hard-mounted, with aluminum pucks instead of rubber.

2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE

Read through all that and you’d expect a joint-rattling ride. It’s certainly stiff, but the person the 1LE will appeal to won’t mind. Everyone else can save some dough and just grab a regular ZL1 with its more compliant rubber mounts and Magnetic Ride suspension.

As radical as the handling hardware is, the powertrain is largely the same. The engine output – 650 hp and 650 lb-ft of torque – and calibration are identical. The Tremec 6060 six-speed manual, the go-to ‘box for American performance cars, has a shorter fifth and sixth. The eLSD has a unique calibration, but the final ratio is the same. That’s pretty much it on the powertrain side.

Chevy did jettison some mass. And by some, I mean a lot. The aluminum bodies on the front shocks, for example, saved 18 pounds of unsprung mass alone. In total, the DSSV shocks are 23 pounds lighter than the Magnetic Ride system found on the regular ZL1. The rear seat is thinner, made of stiffer foam, and won’t fold down – that’s good for some mass reduction. A thinner rear window saves 4-5 pounds. It’s a wash compared to the no-A/C Z/28, which of course was on a larger and heavier platform to begin with, and the current ZL1.

If the equipment the 1LE had underneath it was serious, so was the place we’d be finding out how it all worked together. Area 27 is a brand-new Canadian road course, just north of the American border in British Columbia. It’s long – 3.1 miles – and technical enough to load up the 1LE and toss it around a bit. Some of the nastier turns would chuck an ill-handling, big-power car off with hardly a shrug. It’s a private track club sort of deal, and there’s a lot of hoopla about Jacques Villeneuve’s involvement. And considering the Camaro’s racing history north of the border, in a series obscure to Americans (like the Player’s Challenge series that spawned the ur-1LE itself) but well-remembered by Canadian motorsports nuts, it’s a good place to party.

2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE

And the ZL1 1LE does like to party, and it’s dressed for the occasion. All the aero bits are functional; the massive double-sickle rear wing alone is good for 300 pounds of downforce at 150 mph. Those front dive planes are good for more than dealer revenue when they’re ripped off in the car wash – they also improve downforce, and in a roundabout way help to reduce weight. You see, to make ’em fit GM had to remove the separate daytime running lights, which saved 7 pounds. The DRL units are required in Europe, but Chevy isn’t going to sell the 1LE outside of North America, so it doesn’t matter.

Whether the aero adds any beauty to the Camaro – no one could accuse it of being uncluttered, although it’s certainly purposeful – is for you to decide, but what is undeniable is that the 1LE has the handling to back up 650 horsepower. And the brakes – iron, but at 15.3 front and 14.4 rear, plenty for the Brembo calipers to grab – are up to the task of hauling down a 3,820-pound car in preparation for chucking it into a turn. Driven hard, it’s noticeably more aggressive than the old Z/28, which had a sort of gracefulness you wouldn’t expect in a Camaro. The 1LE is brutish without being brutal, and to get the most out of it you have to work a bit to overcome front end scrub. Expertly manhandled, the 1LE does incredible things.

Ergonomics make the manhandling all the easier. The Tremec six-speed is perfectly geared for a track like this, and rowing it is a joy. This is a variant of a gearbox used in nearly every high-horsepower American car that has offered a manual in the past decade or so, descended from the mighty T-56. The 1LE has the characteristic positive engagement, paired with a pedal box that’s as familiar as your nearly worn-out driving sneakers. It’s like the anti-Viper, a car that used the same gearbox but required contortion for every motion. The same goes for the steering. Who would’ve thought that GM would succeed where legendary companies like BMW have struggled mightily? Just like the C7 ‘Vette, the 1LE’s variable-ratio electrically-assisted steering is precise and predictable, with an appropriate heft and plenty of road feel.

2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE2018 Chevrolet Camaro ZL1 1LE

Maybe it’s the longer wheelbase or the rubber, but the 1LE isn’t a handful despite the LT4 trying to reverse the orbit of the earth at every corner exit. Actually, a lot of that is the combination of the eLSD and advanced traction management software, which left in Track mode is less of a nanny and more of a safety net. As it sat, with the suspension and stabilizer bars set to full track and the software keeping a watchful eye, the 1LE exhibited mild understeer and a bit of throttle intervention on overenthusiastic exits. More than enough bandwidth to learn lines and set initial times. And of course, it can be turned off when the safety net isn’t needed.

At that point, it’s the tires that become the star. Area 27 is more than three miles long, and with a heavy car that likes to push a bit, heat would be a problem in lesser tires. The Goodyears, somehow, managed to take the abuse without developing any nasty habits, staying predictable and sticky soon after track out and until the end of our 2.5-lap stints. How the tire behaves 10 laps in I couldn’t say, and perhaps there’s a gradual falloff in adhesion, but considering the wide and forgiving breakaway characteristics I’ve got no complaints.

As Bill Wise, whose title of ride and handling development engineer doesn’t really do his role justice, told us, “[It] won’t snap on you. You can correct a slide with a bit of steering angle, but you don’t have to back out of the throttle … It’s a lot of car, but we wanted to make it approachable. We really focused on make the car drivable for every customer.” Wise is the guy who set the Nürburgring lap time of 7:16.04, so I wanted to believe him. But this is a 650-horsepower Camaro, and he’s a shoe, so maybe the definition of “driveable” would prove to be a bit fuzzy. As I’d find out soon enough, he was completely correct.

Below, you can see pro drive Lawson Aschenbach put Wise’s words to motion.

You’d think jacking up the loads this much on a streetable tire would mean they’d bite you hard if you overcook ’em, but you can catch the 1LE a country mile before it gets too bent out of shape. And remember, this is DOT-legal rubber.

Coming off the track, I had a realization that a word I hate was the perfect one to describe the 1LE’s relationship with Area 27: “synergy”. Take a minute to grab the eye bleach; I’ll wait. All good? The 1LE isn’t the low-key track assassin that, say, the GT3 is. It’s dramatic. Motions are big, the sound is intense, the grip is tremendous. Picture a vintage Trans-Am car that isn’t trying to kill you, that’ll actually idle. It’s entertaining, not just because the limits are huge, but because the danger zone as you work up to the limit is as fat as those Goodyears. If you loop the thing, well, it’s not like you weren’t warned.

There might be more enjoyable cars out there for $ 70,990, but of that subset not too many seem to snub physics and prejudices quite like the 1LE. Compared straight-across to the regular ZL1, the $ 7,500 premium seems like a deal. It’s a lot of money, but it’d take some serious aftermarket development to get the kind of handling out of the thing. Look, GM and its cohorts at Multimatic and Goodyear did all the hard stuff. Pay the guy the money and go play on the track, and whup on Mustang GT350s.

As for me, I miss the old Z/28 a bit – that 7.0-liter didn’t pull like the LT4, but it still ripped. It also didn’t suffer from excessive aero syndrome, whereas the 1LE looks like it plowed into a carbon fiber sheet manufacturer, popped out the other side, and drove straight to the track. And yet, for the guy or gal who is a slave to the stopwatch, the results speak for themselves (and maybe to the wallet; the much more powerful 1LE is actually cheaper than the old Z/28 was back in 2013).

You know what? While you think about the price and competition, and whether the 1LE is the RPO for you, I’ll just sneak off for a few more laps. Don’t wait up for me.

–

The dynamic rear wing on new Porsches (such as the 718 Boxster pictured above) may soon be joined by a rear diffuser that automatically deploys itself in similar fashion. That’s if a recently published patent filed by Porsche with the United States Patent and Trademark Office makes the transition from idea to reality.

–

According to the patent, this rear diffuser mounts to a part of the vehicle’s body (presumably the rear bumper cover) and will be activated by one or more motors. Porsche’s patent further reveals that the device is theoretically designed to be able to span either the full width of the vehicle it’s attached to or only a portion of the vehicle’s rear end. It also notes that the technology can be designed to fit vehicles with or without an internal-combustion engine.

–

A diffuser is an aerodynamic device used to generate downforce. It works as an expansion chamber, lowering the air pressure underneath the car by channeling it out the rear through a cavity that is largest at the tail of the car. Vertical strakes fitted to the rear of the diffuser further assist in the evacuation process. The net result of a functional rear diffuser is an increase in downforce, which helps keep the car’s rear tires firmly planted to the tarmac. Porsche isn’t the only automaker looking to employ a trick dynamic rear diffuser, either; a recent patent filing by General Motors reveals that the Chevrolet Corvette is likely to see a host of dynamic aero tricks added to its body, including a dynamic rear diffuser.

–

–

While Porsche’s dynamic rear diffuser is, as far as we know, merely a patent design at this point, we wouldn’t be surprised to see the technology make its way to a forthcoming Porsche model such as the next Cayman GT4 or even the production version of the all-electric Mission E concept. After all, the Mission E will need to walk a delicate line of EV efficiency and Porsche-worthy performance, a feat that dynamic aero technology could help achieve.

A new aviation startup is launching out of stealth today with plans to facilitate a U.S. regional hybrid-electric aircraft network by the beginning of the next decade.

Founded out of Kirkland, Washington in 2013, Zunum Aero is striving to “take aviation into the future” with 10-50 seat aircraft that use thousands of quieter regional airports to transport people up to 700 miles starting from the early 2020s. The company says it expects to increase the range to 1,000 miles by 2030.

In a nutshell, Zunum Aero is looking to better utilize underused airport inventory. Currently more than 95 percent of all U.S. air traffic emanates from only 2 percent of the country’s 5,000 airports.

The long-term aim of Zunum Aero is to build a regional electric air network, offering travelers a 40 percent decrease in door-to-door travel time by using a smattering of local airports, while also promising 80 percent lower emissions. Additionally, the company says it has lower in-house operating costs, which will mean up to 80 percent cheaper fares.

Above: Zunum aircraft

The model that Zunum Aero is working on is more or less designed to replicate that of bus travel — “walk-on, walk-off” aircraft that don’t require a 2.5 hour journey to the nearest major airport. By way of example, passengers can expect to travel from regional airports in the Boston area to Washington, DC for “half the fare and in half the time it takes today door-to-door,” according to a statement issued by the company.

“The shift of the industry to large aircraft and long ranges driven by gas turbines has concentrated almost all air traffic to just two percent of our airports, creating a massive transport gap over regional distances where there is no high-speed alternative,” said Zunum Aero cofounder and CEO Ashish Kumar. “As a result, door-to-door times for most journeys are no better than they were 50 years ago. Hybrid propulsion is an industry-changing solution, enabling mid-sized aircraft on regional routes to have better cost efficiencies than airliners.”

Zunum Aero hasn’t revealed how much financial backing it has, but it says that both Boeing and JetBlue, via its JetBlue Technology Ventures subsidiary, have invested in the company.

“Boeing is investing in Zunum because we feel its technology development is leading this emerging and exciting hybrid-electric market space,” explained Steve Nordlund, VP of strategy at Boeing. “This technology and customer approach has the potential to transform the market for small, short-haul aircraft that can use smaller regional airports.”

Who needs roads?

Though autonomous cars and electric road-faring vehicles have been grabbing most of the transport-related tech headlines of late, there has also been a quiet surge in innovations across the aviation realm too.

Earlier this year, Airbus confirmed plans to test a prototype of a self-piloted flying car by the end of 2017, as it looks to invest in solving the growing gridlock on city roads. This followed shortly after fledgling startup Lilium Aviation announcing a $ 10.7 million funding round for its vertical take-off and landing jet. Elsewhere, Massachusetts-based Terrafugia has been developing working prototypes of roadable aircraft for more than a decade, and it recently received approval from the Federal Aviation Administration (FAA) that paves the way for it to get unmanned passenger vehicles in the skies by 2018.

Keen not to be left behind in any transport-related advances, Uber recently released a whitepaper that considers a time when on-demand urban air transportation is commonplace, with networks of small electric aircraft taking off and landing vertically, bypassing the need for airports at all and opening up routes between cities and suburbs.

“On-demand aviation has the potential to radically improve urban mobility, giving people back time lost in their daily commutes,” the paper reads. “Just as skyscrapers allowed cities to use limited land more efficiently, urban air transportation will use three-dimensional airspace to alleviate transportation congestion on the ground.”

Google cofounder Larry Page is backing not one, but two secret flying car startups: Zee was founded in 2010 with a view toward “designing, building, and testing better ways to get from A to B,” as the blurb on the company’s homepage states. It’s currently working on a “small, all-electric plane that could take off and land vertically,” according to a Bloomberg report.

Page is also reportedly backing a second secret flying car startup called Kitty Hawk, which is based just a stone’s throw from Zee in Silicon Valley.

Zunum Aero has been working with the FAA since 2014 as it looks to help push through certification standards for electric aircraft, an outcome that’s expected next year. And it anticipates that its first aircraft will hit the market in around 2020.
