Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

Top Gear has an Extra Gear problem | Episode Review

When the BBC announced Extra Gear, I was excited. As an avid fan of show's like The Talking Dead – companion show to AMC's hit The Walking Dead – a behind-the-scenes look at my favorite motoring show sounded promising. But with the fifth episodes of each show, I'm worried that Top Gear is suffering to keep Extra Gear interesting. We'll start with Chris Evans, inarguably the most heavily criticized member of the new Top Gear team. Evans is progressively less shouty and more comfortable filming while driving in each episode – the fifth is no different. He's almost likable in the Zenos E10 video, like a ginger James May, and he delivers accurate and eloquent driving impressions. The review is entertaining, until Extra Gear shows the producers cut a huge element – an old-versus-new sprint around the Race of Champions circuit at the Olympic Stadium in London. Former Formula 1 ace David Coulthard would drive a Caterham 360, while current F1 pro Daniel Riccardo rocked the Zenos. If the entire premise of Evans review is that the Zenos E10 is the newest of the new for British super-lightweight track toys, why did the producers decide to leave a race against the segment's standard bearer for Extra Gear? It's a baffling move, cutting a segment of the film that reinforces Evans' excitement over the Zenos. Rory Reid's Jaguar F-Type SVR piece is excellent. Fifty five years to the day after Jaguar test driver Norman Dewis raced to the Geneva Motor Show in a second E-Type for display, Reid would attempt the same feat in an SVR. If he failed, Jaguar wouldn't have a car to display. Dewis made the 750-mile trip with 13 hours of notice, and Reid would need to do the same. It's a brilliant, simple premise that reminded me of Jeremy Clarkson's so-called "Race against God" in a Jaguar XJ, way back in season 16. The history of the challenge and Dewis' gravelly commentary add gravitas. But the entire film goes by so fast. It's longer than Evans' Zenos video or Harris' BMW M2 film, but at less than ten minutes, Reid and the SVR deserved more screen time. Extra Gear poured salt in that particular wound with a great segment featuring Norman Dewis that deserved to be in the main show. Reid takes the famed test driver for a spin around the Dunsfold track, then, instead of the comedian of the week, the hosts interview Dewis on Extra Gear's couch.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.
