2014 Audi RS7 [w/video]

The subject of what makes up a true "supercar" is a difficult one, fraught with personal connotations and the rare ability to bring close colleagues into heated confrontation with one another in the blink of an eye. I say this because, while the 2014 Audi RS7 most certainly does not make the supercar cut on a few levels to my way of thinking - not rare enough, expensive enough or wearing an appropriately evocative body - it is unquestionably an "everyday supercar" of remarkable ability. And, pertinently, it is one that proved willing to ply its trade in every version of winter that Michigan had to offer it.
I had winter four ways during my week-long loan with the RS7. A period of crisp temperatures and dry roads, presided over by light blue skies as wide as the horizon, soon gave way to spitting, freezing rain blanketed in slightly misleading warmer air. Then there was snow. Not the massive blanket we saw in the first week of the New Year, but more than enough to see my neighbors stocking up on Ice Melt and replacing their shovels for the season. Finally, temperatures dropped to the mid teens, cottony snow compressed into a hard pack and all residual moisture on the mostly cleared roads morphed into the very slickest of ice. Timeless curses were uttered by cranky commuters in smoking breaths. Pure Michigan.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

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.
