Audi R8 Spyder looks like heaven at the Green Hell

After Audi took the wraps off the new R8 coupe at the 2015 Geneva Motor Show, we knew it would only be a matter of time before the convertible version arrived. Now, we've spotted the droptop during testing on and around the venerable Nurburgring Nordschleife in Germany. The new Audi R8 Spyder is expected to closely mirror the fixed-roof supercar we've already seen. Only instead of a tin top, of course, it'll have a folding fabric roof mechanism. This goes against the recent retractable hardtop trend, and the featured is used by the Ferrari 488 Spider and McLaren 650S Spider. Some revised air vents appear to be part of the R8's convertible package, as well. Otherwise, we can anticipate the same specs as the R8 coupe. The latest model ditched the previous version's V8 engine in favor of 10-cylinder options: a 5.2-liter V10 with either 533 horsepower in "base" spec or 602 hp in the V10 Plus model. Both drive all four wheels through a seven-speed dual-cluch transmission. The jury's still out on whether Ingolstadt will slot a smaller engine option into the R8, particularly for markets where tax brackets are determined by engine displacement. But whatever the coupe gets, the convertible is likely to offer it as well. Related Video:

Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.
