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.

Mercedes has X6 in its crosshairs with the GLE Coupe

In the last month, Mercedes-Benz has taken the sheet off two versions of its GLE Coupe: the 450 AMG and Mercedes-AMG GLE63 S. The models represent the German brand's shot across the bow at the BMW X6 in the luxury-crossover-four-door-coupe segment, including the high-performance M version of the bodystyle. Not much separates the styling between the two versions. Both feature sweeping arches over the hood and roofline to create their coupe-like appearance. Up front there are huge air intakes with a wide grille on top that's bisected by the brand's traditional star. The AMG version tweaks that look with the division's A-wing grille. At the rear, there are wraparound taillights and a chrome strip. The higher performance version also sports a modified diffuser and air outlets. No matter which one buyers choose, they get a healthy amount of power nestled under the hood. The 450 AMG packs a 3.0-liter, twin-turbo V6 with 362 horsepower and 384 pound-feet of torque with a nine-speed automatic. Opting for the GLE63 means a massive boost with 577 hp and 561 pound-feet from a 5.5-liter twin-turbo V8 routing through a seven-speed auto gearbox. Either way, customers get Merc's 4Matic all-wheel drive system. The luxury crossover coupe segment is often maligned for looking awkward, but Mercedes clearly sees room to grow there. Check them both out live from the 2015 Detroit Auto Show floor in the galleries above.

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.
