MTM Audi RS6 Clubsport might be overkill for grocery shopping

As automotive journalists, we're biologically wired to love station wagons. We really don't have a choice. And while we prefer brown, diesel-powered, manual-transmissioned long-roofs, we suppose a 750-horsepower Audi RS6 Avant would be just dandy. This is the MTM RS6 Clubsport, and as we mentioned, it's very powerful. That's thanks to a modified version of Audi's critically acclaimed 4.0-liter, twin-turbocharged V8. While 750 hp out of just 4.0 liters is impressive, 697 pound-feet of torque is an equally big accomplishment. And if that's not enough, MTM has managed to shave nearly 200 pounds of body fat from the big wagon. Needless to say, it's very, very fast. MTM has displayed a degree of aesthetic restraint, eschewing the gaudy body kit favored by some other tuners and simply opting for a questionable paint job. The 21-inch wheels look good, although with the smattering of rubber around them, we wouldn't bet on a comfortable ride. As for the cabin, well, MTM got a bit out of hand. It's very, very orange. The seats are essentially carbon-fiber shells lined with bits of orange, leather-wrapped padding here and there. Orange, quilted-leather in the door panels, center armrest and on cushions on the side of the center console – a nice touch we wish more automakers would add to their performance cars – contrasts nicely with the black plastics and carbon fiber found on the rest of the dash and center console. That said, we aren't crazy about space for passengers, thanks to the large cage that's there to boost structural stiffness. We have a full gallery of photos of the MTM RS6 Clubsport direct from Geneva. Trust us, you'll want to have a look at this one. Related Video:

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

Stunning Sportback Gets The Performance To Match
Saying the 2014 Audi RS7 Sportback is not as good as the not-for-North-America Audi RS6 Avant we recently tested is a bit like saying one more strip of crispy bacon would make our Waffle House All-Star Special breakfast even more special. The RS7 goes to ten while the RS6 goes to eleven, maybe, but they both rock our world. The RS7 is meant for the far wider buying audience worldwide, not just for western European family bombing runs, as with the RS6 Avant.
But, hey, this RS7 simply hurtles down the road in a singularly sexy way. And if you really want this bodystyle - and who could blame you? - the RS6 Avant doesn't really even matter anyway. After a full day on perfect dry and warm Swabian two-lanes driving this Audi very hard, we barely thought about it at all.
