Mercedes GLE63 AMG Coupe teased

The very concept of the luxury crossover coupe often gets flamed for being not only ugly, but also impractical. However, after years of letting BMW blaze the trail with the X6, Mercedes-Benz recently entered the field with the GLE-Class Coupe. Now, it's time to add a little more pepper to the package with the newly teased GLE63 AMG Coupe. The video above gives a solid look at the three-quarters perspective of this high-performance high-rider. Compared to the standard version buyers get a different front bumper with larger air intakes and an arching wing that almost appears to be floating in space. Flashes in the clip show off AMG branding for the brake calipers, steering wheel and seats, as is expected. This is clearly not a vehicle that'll appeal to everyone, but it offers an alternative to the latest BMW X6 M with 567 horsepower and 553 pound-feet of torque. Mercedes isn't saying what lies under the hood of the GLE63 AMG Coupe yet. Although given the name, we suspect a version of the brand's 4.0-liter twin-turbocharged V8 is the likely choice. It's offered in the latest C63 AMG with either 469 or 503 hp. The debut for this CUV coupe is possible at the upcoming Detroit Auto Show, where the standard GLE Coupe will be unveiled.

Maybach could become Mercedes-Benz sub-brand

When you're arriving in a twin-turbocharged, twelve-cylinder Maybach limo, there's no reason you should ever have to be late. Except, maybe, to make a fashionable entrance. But up at the corporate level, the entire Maybach brand is being slowed down as critical decisions about its future are being undertaken.
Last week, we reported that a decision on what path Maybach would take going forward would be due at the start of next month, but the latest reports indicate that the timeframe has been extended as further options are being considered.
The previous options under consideration were twofold: either relaunch the brand with production outsourced to Aston Martin - which suddenly finds itself with excess production capacity - or shut it down completely. And those are still two very real options. Word has it that Aston has put together four concept cars for the Daimler brass to consider, all based on the next-generation S-Class platform (and thankfully not the old one).

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.
