Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

Audi R8 Spyder is latest big New York Auto Show debut

The New York Auto Show hasn't been boring. Highlights so far are the kick ass Mazda MX-5 Miata RF and the new Lincoln Navigator Concept. And now, Audi has added a healthy dose of supercar to the mix with the new R8 Spyder. The headlining stats are familiar, seeing as how they're plucked directly from the new R8 hardtop. The only powertrain option is the 5.2-liter V10 and seven-speed S-Tronic dual-clutch transmission. That engine, as in the hardtop, is good for 540 horsepower and will get this droptop German to 62 miles per hour in just 3.6 seconds (only a tenth of a second off the Coupe's time). The convertible R8 will run all the way up to 197 miles per hour. Audi's release makes no mention of a higher-performance V10 Plus model, which is available on the R8 Coupe. That top-end trim bumps output to 610 ponies and cuts three-tenths of a second off the base hardtop's 3.5-second run to 60. The upside, of course, is unlimited headroom. The new fabric roof can be opened or closed at speeds up to 31 miles per hour, and the operating time is 20 seconds in both directions. The R8 Spyder hasn't exactly been a secret. We've spotted it testing as recently as August, and it was included on a leaked product road map last month with a listed March/April debut. Check back later for a full round of live images from the R8's New York debut. Until then, check out our first images of the new R8 Spyder, available up top.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:
