Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

2015 Audi A3 Cabriolet

When my 758-mile journey on the A3 TDI Challenge came to an end in Boulevard, CA, Audi had a very nice consolation prize waiting for me: the 2015 A3 Cabriolet you see here. And with miles left to drive before reaching my hotel in Coronado (just outside of San Diego), what better way to celebrate my personal victory of achieving nearly 60 miles per gallon in the TDI than to run the rest of the route in couple of turbocharged A3 droptops? After all, the efficiency part of my drive was done, so it was time to have some fun. The A3 Cabriolet comes to market just as the sun sets on another four-seat convertible from the Volkswagen Group stable: the Eos. That car, often criticized as being too expensive, is technically replaced by the Beetle Convertible as far as VW-badged products go. But for those who still prefer something a bit more upmarket, the A3 Cabriolet will fill the void nicely, and with more style and grace than the Eos ever had. Driving Notes The A3 Cabriolet arrives with a choice of engines. On the base end lives a 1.8-liter turbo-four with 170 horsepower, 200 pound-feet of torque and front-wheel drive, or you can pony up for the 2.0T with 220 hp, 258 lb-ft and standard Quattro all-wheel drive. Regardless of engine, the only transmission available in the A3 Cab is Audi's six-speed S-tronic dual-clutch unit. This is a fine cog-swapper, with quick shifts regardless of chosen powertrain, and steering wheel-mounted paddles that offer plenty of fun from behind the wheel. That said, I found it best to just leave the transmission alone, no matter the engine. The paddles are entertaining, sure, but slick the gear selector into Sport and the A3 will instinctively hold gears through turns and always have you right in the heart of the powerband. The 1.8T's 170 hp and 200 lb-ft are more than adequate for duty in the 3,373-pound A3 Cabriolet. I was never bothered by a lack of power, especially with the engine on boil with the transmission in its sport setting. Hitting 60 miles per hour takes 7.4 seconds, en route to an electronically limited top end of 130 miles per hour. If speed is your thing, though, the 2.0T certainly delivers quite a punch. That same 0-60 sprint takes just 5.9 seconds with the more potent powerplant, and you can really feel the stronger rush of power right off the line, even with the quicker A3's 210-pound weight penalty.

The hottest modern sports cars rendered as rally racers

The modern-day World Rally Championship a monumental amount of fun to watch – I should know, as I recently was lucky enough to head to the UK to watch WRC Wales Rally GB – but even the most monstrous of the current WRC cars are based on fairly pedestrian European hatchbacks. Back in the heyday of rally, the Group B era in the 1980s, much hotter cars were the basis of even more incredible competition machines, for the most part. Take the exotic Ford RS200, or the Lancia Delta S4 with its twin-charged engine. And the hatchback-based Group B cars were bonkers, too. So what would some of our favorite modern cars look like if Group B had never ended? A British site named CarWow hired an artist to reimagine everything from the Rolls-Royce Wraith to the Porsche 911 as a retro-inspired rally car, and they were kind enough to let us share the results in the gallery above. The gallery features an Alfa Romeo Giulia in Martini livery, an Audi TT in classic Ur-Quattro colors, a Fiat 500 Abarth sporting massive flares and a hood blister full of auxiliary lights, a new Ford Mustang in RS200 livery, a Lancia Delta in Alitalia colors, a Porsche 911 in Rothmans livery, a Renault-Alpine in classic blue, a Rolls-Royce Wraith tribute to the Jules cologne Corniche Coupe, and a relatively modern-looking VW Touran. So far, the favorite around the office is the incredible Mercedes-Benz S-Class that is an homage to the wonderful 300 SEL 6.8 AMG "Red Pig" that essentially put AMG on the map. Check out the gallery above and see which one you like the best. Related Video:
