Entry-level Audi R8 to go turbo after all?

Would you be shocked if we told you that the better version of the Audi R8 offered a V8 engine rather than a V10? There was something inherently lovable about the company's 4.2-liter V8. Maybe it was the noise or the high-revving nature or some combination of the two, but the R8's original engine is a darn hoot. Sadly, the V8's days appear numbered in the brand's flagship model, according to a new report from Car, which claims Audi will ditch the beloved, off-angle 4.2-liter for a 2.9-liter, twin-turbocharged V6. The rumor cites sources in Ingolstadt who claim the new engine will develop 450 horsepower, up 20 ponies on the current entry level engine. We'd expect a commensurate increase in fuel economy too, befitting of a smaller, force-induced engine. Still, this is counter to what we've heard before. But, if the report proves true, the R8 will join the ranks of turbocharged supercars like the Ferrari 488 GTB and California. It's unclear when such a switch would be made, but according to Car, we can place the blame squarely on China. The country has been combating large-displacement engines since 2008, attaching massive taxes on vehicles with anything larger than a 3.0-liter engine. It's China's position, Car reports, that led to the death of another beloved, naturally aspirated V8, Mercedes-AMG's 6.2-liter model. First the venerable M156 and now Audi's 4.2-liter V8? Just stop this silliness China. Related Video:

Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain

If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly. Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles – it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management – the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency. Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles. The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van. The Audi A7 Sportback h-tron quattro It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars. "The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e-quattro, its two electric motors drive all four wheels," explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "The h-tron concept car shows that we have mastered fuel cell technology.
