Audi RS6 Avant and Mercedes-AMG E63 S drag race for Top Gear

Sometimes the kids are late for school, and you need a wagon to get them there in a hurry. In its latest drag race, Top Gear finds out which is the quicker high-performance family hauler: the Audi RS6 Avant or the Mercedes-AMG E63 S. The specs suggest this race should be quite close at the finish line. The RS6 has a 4.0-liter twin-turbo V8 with 552 horsepower, but the E63 S is a little more powerful with 577 hp from a 5.5-liter twin-turbo V8. However, the Audi has a traction advantage from the all-wheel drive system, whereas the Mercedes only spins its rear wheels. Pick your favorite, and then watch the video to see if the similar numbers translate to a photo finish in the real world. Related Video:

Recharge Wrap-up: Porsche 911 hybrid possible, Ecocruise EVs coming soon

The next-generation Porsche 911 could use hybrid power, according to Porsche CEO Matthias Muller. "There is no reason against it and we will see if we have some reasons to do it," Muller says of the model due around 2018. He also suggests that hybrid technology could eventually make its way into all Porsche model lines, but that the Boxster and Cayman would first get four-cylinder versions. Muller cites carbon emissions and "sportiness" as reasons to use hybrid power, pointing to the 918 Spyder as a good example of both. Read more at Car Advice. A B-Class F-Cell from the Mercedes-Benz fleet has hit a benchmark of 300,000 kilometers (about 186,411 miles) in everyday use. The achievement won Daimler an "f-cell award" for hydrogen fuel cell technology and innovation. The 300+ fuel cell cars in the Daimler fleet have driven a collective 9 million-plus kilometers (more than 5.5 million miles). The information gathered from this testing is being used to improve development as the company looks toward expanding commercialization of fuel cell cars. "We have clearly demonstrated that the fuel cell electric drive is ready for the road," says Professor Herbert Kohler of Daimler. "The last hurdles we will overcome in intensive cross-industry and cross-border teamwork." Read more in the press release below. A company called Ecocruise has new EVs coming out soon. Along with electric scooters and service vehicles, Ecocruise develops street-legal neighborhood electric vehicles like the three-wheeled EZip-3, the four-wheeled EZip-4, and the fun looking Cruser Sport (see a prototype in the video below). The EVs are scheduled to go on sale in January of 2015, which is right around the corner. Ecocruise was started after the founder of Kasea Motorsports decided to switch to electric vehicles with the goal of offering providing affordable emissions-free driving. Learn more about Ecocruise and its vehicles at the company's website. The new EU Fuel Quality Directive (FQD) does little to discourage dirty fuels like tar sands and coal-to-liquid, says Transport & Environment (T&E). The FQD requires suppliers to reduce greenhouse gas intensity for transport fuel in the EU by six percent by 2020. The much-delayed FQD doesn't do as much as it could, though, say critics, and it doesn't label dirtier fuel sources as such despite the urging of scientists. T&E, an organization focused on cleaning up EU transport, blames Canada, the US and Big Oil.

Promo video shows what the Mercedes G500 4x4 can do

The Mercedes-Benz G500 4x42 is still nominally a show car, but it they're not treating it like one. They've provided their usual video follow-up to the press release and still photo launch, and they've made enough of the beasts to hold a press launch in Granada, Spain. It's even got AMG's brand new twin-turbo V8 engine in it, one that gets the 6,000-pound truck from 0-62 miles per hour in about 6.5 seconds. The only thing it needs to be a going concern is license plates; we guarantee it's not waiting on customers. Autocar could be jumping the gun, but they say it's expected to go on sale later this year for a price in excess of 200,000 pounds ($308,770 US) in the UK. Above is the promotional video, below is footage from GT Spirit from the press launch – notice how the G63 AMG in the background looks, shall we say, pedestrian. We're going to be crawling all over this truck at the Geneva Motor Show, and if we can find the keys, we might even drive it over the other show cars and out the door... or the nearest wall.
