Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

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 bringing TT Clubsport Turbo concept to Worthersee

Is the world ready for an Audi TT with 600 horsepower? Well it had better be, because that's exactly what Ingolstadt has in store for this year's GTI-Treffen at Worthersee, Austria. Billed as a "technology concept," this TT show car packs a 2.5-liter inline-five with two electric turbochargers. Audi is developing electric turbos for its diesel engines, but has found a performance application here in a gasoline engine. The result is a whopping 600 horsepower and 479 pound-feet of torque, driving all four wheels through a six-speed manual transmission. Weighing in at 3,078 pounds and with those electric turbos spooling up quick, it's said to reach 62 in 3.6 seconds en route to a top speed of over 192 miles per hour. In a TT. The turbos are powered by a 48-volt electrical system, juiced by a compact lithium-ion battery in the trunk that can store regenerated power. It's also got a coilover suspension and electric jack to get over obstacles like curbs and speed bumps. The whole thing rides on 20-inch alloys with a two-tone finish, with carbon-ceramic discs to keep it all in check, and as you can see, a rather aggressive-looking widebody aero kit. All of which makes for a rather stunning concept, even if its encroachment on the R8 means it will likely never see production.

From May 13 to 16, Audi will be showing its technology concept car on the Worthersee Tour in the Austrian town of Reifnitz. The inspiration for the show car came from the successful Audi 90 IMSA GTO of the late 1980s. A new technology is making its debut under the hood. The car's electric biturbo adds even more dynamism to the driving experience with its spontaneous response. "The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power," explains Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. "In our TDI engines, we are close to production readiness with this technology.
