Xcar weighs in on the five best-sounding modern cars

Getting behind the wheel of a well-balanced vehicle can be a wonderfully visceral experience, thanks to the combined feeling of things like the weight of the steering, the bite of the brakes, and, of course, the roar of the engine. Unfortunately, many of the sensations of driving require actually being in the driver's seat to understand them, but thankfully the intoxicating noise of a beautifully tuned internal combustion engine can be shared with everyone. In a new video, Xcar shares their opinion on the five best-sounding modern performance cars. The list is a symphony of horsepower. As opposed to keeping all of the vehicles brand new, Xcar actually picks a few that are recently off the market. They're all definitely champs, though. While the list itself is well stocked, you might be able to argue with the specific order, and it would be nice to hear a few participants from outside of Europe for a collection like this one, too. No matter. Every listener is sure to find something they like in the bunch, though. Turn up the volume and enjoy.

Audi teases 700-hp Quattro Sport E-Tron concept for Frankfurt

Audi's trump card for the 2013 Frankfurt Motor Show has just been unveiled, sort of. It's called the Quattro Sport E-Tron Concept. Set to debut in a few weeks, sketches have been uncovered that show a few of the car's details, albeit in rough form. The news of a big-name Audi concept at Frankfurt has been swirling since June, when we first reported on it.
From the sketches, we see a car that has the same basic shape as the Quattro Concept from the 2010 Paris Motor Show, only with subtle tweaks and evolutions to a few features. The news isn't so much about the looks, though. It's the reports coming from Auto Zeitung and Audi enthusiast site Fourtitude.
Horsepower on the concept is expected to be in the neighborhood of 700 ponies - about 50 more than we initially thought - and will be split between a gas engine and an electric motor. Yup, that "E-Tron" name isn't just there for show. While it's not clear what the exact split will be between gas and electric power, we do know the same twin-turbo 4.0-liter V8 found in the RS6 and RS7 will be sitting under the Quattro's hood, and that the bulk of the power will likely come from here. We may not have power figures on the hybrid system, but we do know this concept is capable of running for 21.7 miles on electric power alone.

2013 Audi RS6 Avant hauls ass and then some

Holy moly. Despite the fact that Audi first released details on its 2013 RS6 Avant back in December, we're still just as smitten with it now as we were a couple months ago. And why wouldn't we be? This stunning piece of forbidden fruit combines two of our favorite things: fast Audis and useful wagons.
The meat and potatoes behind the RS6 Avant is its twin-turbocharged 4.0-liter V8, tuned to crank out 560 horsepower and 516 pound-feet of torque. Mated to an eight-speed automatic transmission, the all-wheel-drive wagon can scoot to 60 miles per hour in just 3.9 seconds, on its way to a top speed of 155 mph. Opting for the Dynamic package ups that v-max to 174 mph, and selecting the Dynamic Plus pack increases that even further to 190 mph.
This RS6 Avant certainly looks the part of an extreme ass-hauler, fitted with the usual RS-spec gaping air intakes, 21-inch wheels, sport exhaust and carbon fiber ceramic brakes. Combine all that goodness with dynamic ride control, an adaptive air suspension and torque-vectoring Quattro all-wheel drive, and we have no doubt that this thing will scare off every other station wagon in the parking lot. (Well, except maybe that Mercedes-Benz E63 AMG. Woof.)
