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.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Mercedes A-Class refresh includes crown-stealing 381-hp A45 AMG

We're sure the 362-horsepower Audi RS3 Sportback enjoyed its brief reign at the top of the hot-hatch horsepower charts. But now, Mercedes-Benz updated the A-Class so that it reclaims the throne, castle, and jewels: the Mercedes-AMG A45 4Matic comes with 381 hp from its turbocharged 2.0-liter four-cylinder, a significant bump of 36 hp, and 350 pound-feet of torque, an increase of 18 lb-ft. The seven-speed dual-clutch gearbox gets shorter ratios from third to seventh gears, so its 0-62 mile-per-hour time has dropped from 4.6 seconds to 4.2 seconds. The A45 gets a Dynamic Select system – driving modes controlled by a rotary knob – that comes standard with four modes: Comfort, Sport, Sport +, and Individual. Opt for the AMG Dynamic Plus package and you get a mechanical locking differential on the front axle, the two-stage AMG Ride Control sport suspension with adaptive damping, and a Race mode. Outside, additional aero aids are applied to the nipped-and-tucked bodywork changes made to the entire A-Class range. The spoiler lip under the new front bumper, rear roof spoiler, and rear diffuser, create more downforce than before. Inside, the new flat-bottomed steering wheel is joined by sport seats that allow bolster depth adjustment. And for all those upgrades, fuel economy has stayed the same at 6.9 liters per 100 kilometers on the European cycle. Even away from that tectonic shift, Mercedes made plenty of changes to the A-Class landscape. The new front bumper is said to be "more arrow-shaped," in homage to the the Concept A-Class from 2011, that stretches its look horizontally. LED headlights, standard on the A45, are optional here, and are paired with interior ambiance lighting. In back we get new taillights and some angular exhaust finishers laid into a diffuser-like insert, an alteration we're seeing across the entire Mercedes line-up. Inside, you'll find a redesigned instrument cluster with new graphics, higher-quality finishes on the switchgear, seats with adjustable bolster length, and new color options. Four driving modes are incorporated into the Dynamic Select system: Comfort, Sport, Eco, and Individual. The Eco mode has been tweaked to return even more fuel savings. This Mercedes is also the first to incorporate Apple CarPlay and MirrorLink for the non-iOs smartphoners.
