Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi R8 V10 Plus vs. Renault Clio Cup racecar will make you go hmmm...

Match up a hot hatch with a supercar of the same vintage, and we'll tell you who will win every time. It's easy, really, as the supercar invariably features a more advanced suspension, stickier tires and most importantly, more power. What if the hot hatch is race prepped, though?
In that particular case, all bets are off. A circuit-tuned suspension, a stripped-down cabin, an ultra-quick sequential transmission and the greatest equalizer of them all, slick tires, are all that's needed to turn the typical hot hatch into a proper dragon slayer.
Perhaps seeking to prove this, Evo has put together an interesting head-to-head between the Audi R8 V10 and a race-prepared Renault Clio Cup. Host Dickie Meaden takes us through each car, highlighting the bits and bobs on both sides which should make this a tight competition. And boy, is this one tight.

Audi S8 Plus packs 605 horsepower

Audi doesn't offer an RS 8, and probably never will. But with the release of the new S8 Plus, we wonder if it will ever have to. Because Ingolstadt's new flagship performance sedan packs a mighty punch. "Plus" doesn't even begin to describe the enhancements Audi and Quattro GmbH have wrought on the ultimate new version of the A8 sedan. Power is increased from 520 horsepower to 605, besting anything else in its class. Only the Mercedes S65, which packs four more cylinders and two additional liters of displacement, offers more horsepower. Torque is quoted at 516 lb-ft – a gain of 35 – and can deliver up to as much as 553 lb-ft in overboost. That bests any eight-cylinder performance sedan save the S63. The force-fed V8s in the Jaguar XJR, Maserati Quattroporte, and outgoing Alpina B7 don't stand a chance. All that muscle translates to a 0-62 time quoted at 3.8 seconds. Top speed is governed as usual to 155 miles per hour, but can be derestricted to nearly 190 with the Dynamic package that comes standard in Germany – one of the few places where top speed actually matters. Carbon-ceramic brakes keep all that power and pace in check, nestled inside 21-inch wheels. Naturally, Audi gives the S8 Plus a wide array of visual upgrades inside and out to set it apart from "lesser" versions, and is offering it in an exclusive matte silver finish. Of course none of those enhancements come cheap. In its home market come the end of November, Audi will charge 145,200 euros for the S8 Plus, representing a 28k premium over the existing S8. That also places this as the new top of the line, commanding a higher price than even the long-wheelbase, dozen-cylinder A8 L W12. We're waiting on word as to whether Audi will bring the new S8 Plus to America, where it would likely similarly cost over $140k. The pinnacle of sportiness – the new Audi S8 plus - Highest powered sport sedan in the premium segment - 4.0 TFSI engine outputs 445 kW (605 hp) and up to 750 Nm (553.2 lb ft) - Zero to 100 km/h (62.1 mph) in 3.8 seconds; top speed of up to 305 km/h (189.5 mph). Audi is making a strong statement with the new S8 plus*. With a power output of 445 kW (605 hp) and a top speed of up to 305 km/h (189.5 mph), the new Audi S8 plus* delivers even more enhanced driving performance. The new top model is reinforcing the brand's position in the segment of premium class sedans. "We have further sharpened our large sport sedan," says Prof. Dr.
