Test drive the Mercedes SLS AMG Electric Drive with Chris Harris

It's hard to not like the Mercedes-Benz SLS AMG GT. The all-aluminum coupe is fitted with a wonderful naturally aspirated 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque. Not only does the burly combustion engine launch the two-seater to 60 miles per hour in less than four seconds, but it does so with one of the world's greatest exhaust soundtracks as it roars, burbles and cackles down the road.
But what happens when Mercedes-Benz takes away the V8 and its accompanying fire-burning song? Stripped of one of its most appealing assets, does the SLS lose its soul?
Chris Harris recently had the opportunity to take the Mercedes-Benz SLS AMG Electric Drive for a track spin in Europe. Sans gasoline, but with four electric motors providing a combined 740 horsepower (737 pound-feet of torque), all-electric all-wheel drive coupe uses sophisticated torque vectoring and a multi-mode operating system to put oversteer - drifting! - back into the equation. Fun? You bet. See for yourself, below.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.

Mercedes-AMG GT3 racing towards Geneva debut

So far, we've only seen the fundamental road-going coupe version of the new Mercedes-AMG GT, but like the Porsche 911 it targets, you can bet there will be more derivatives to follow. And this is our first glimpse at the first of them. At the Geneva Motor Show next month, Mercedes will showcase the GT3-spec racing version of the AMG GT. The German automaker didn't tell us much more in making the announcement, but did release a pair of cropped teaser sketches showing the sports car with all manner of racing appendages, including what looks like a massive rear wing. Once ready for action, the new Mercedes-AMG GT3 will replace the previous SLS AMG GT3 that won the Nurburgring 24-hour race a couple of years back. But with every automaker and its sister company getting in on the GT3 racing action these days, it'll face some stiff competition on the track. The new Mercedes-AMG GT3 February 12, 2015 Neatly coinciding with the upcoming market launch of the road-going version of the Mercedes-AMG GT, the next stage of the vehicle's evolution is already here: the sports car and performance brand of Mercedes-Benz is presenting a new customer sport racing car that complies with FIA GT3 race regulations in the form of the new Mercedes-AMG GT3. With this, the second customer sport car to be developed by Mercedes-AMG, the Affalterbach company is seeking to build on the success of the SLS AMG GT3 and further expand the customer sport programme first started in 2010. The superb racetrack performance of the road-going GT forms the ideal basis on which to model the new Mercedes-AMG GT3, which is due to make its debut appearance at the Geneva Motor Show.
