Audi bringing TT Clubsport Turbo concept to Worthersee

Is the world ready for an Audi TT with 600 horsepower? Well it had better be, because that's exactly what Ingolstadt has in store for this year's GTI-Treffen at Worthersee, Austria. Billed as a "technology concept," this TT show car packs a 2.5-liter inline-five with two electric turbochargers. Audi is developing electric turbos for its diesel engines, but has found a performance application here in a gasoline engine. The result is a whopping 600 horsepower and 479 pound-feet of torque, driving all four wheels through a six-speed manual transmission. Weighing in at 3,078 pounds and with those electric turbos spooling up quick, it's said to reach 62 in 3.6 seconds en route to a top speed of over 192 miles per hour. In a TT. The turbos are powered by a 48-volt electrical system, juiced by a compact lithium-ion battery in the trunk that can store regenerated power. It's also got a coilover suspension and electric jack to get over obstacles like curbs and speed bumps. The whole thing rides on 20-inch alloys with a two-tone finish, with carbon-ceramic discs to keep it all in check, and as you can see, a rather aggressive-looking widebody aero kit. All of which makes for a rather stunning concept, even if its encroachment on the R8 means it will likely never see production.

From May 13 to 16, Audi will be showing its technology concept car on the Worthersee Tour in the Austrian town of Reifnitz. The inspiration for the show car came from the successful Audi 90 IMSA GTO of the late 1980s. A new technology is making its debut under the hood. The car's electric biturbo adds even more dynamism to the driving experience with its spontaneous response. "The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power," explains Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. "In our TDI engines, we are close to production readiness with this technology.

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.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
