Mercedes-AMG could use electric turbos

Mercedes-Benz is joining Audi in analyzing electric turbochargers for its production cars. But while Ingolstadt will roll out its first e-turbo in its A8 luxury sedan, Stuttgart is studying the technology for use in small performance cars, like the A45, CLA45, and GLA45 AMG models. Auto Express spoke to Mercedes-AMG compact car boss Steffen Jastrow about the cutting-edge tech, which reduces turbo lag, improves fuel economy, and occupies less space under the hood than a standard turbo. "Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain." Jastrow said. "They have to be faster and e-turbos are an option. We use them in motorsport, but the technology has to be payable for the customer." As AE tells it, bringing the price of e-turbos down from the A8's luxury car level to the relatively affordable sums demanded by compact AMG models will still take some time. So don't count on seeing a Mercedes with an electric turbocharger until the new A-Class arrives in 2017, at the earliest. Related Video:

Mercedes A-Class next up for facelift

This is the coming Mercedes-Benz A-Class, and in case the paucity of camouflage didn't make it clear, it won't look much different the one that's been on sale for all of two years. Caught in Sweden braving the temperatures, its exterior updates aren't expected to go much further than a reworked face that brings it in line with the recently updated B-Class, including a new grille, headlights and taillights, and bumpers. The cabin is where most of the work is being done, to give it a better punch against the BMW 1 Series. A tweaked dash cluster, better fabrics and materials, the eight-inch tablet-style nav/multimedia screen, and ambient lighting should join the party. The updated range of B-Class engines should also make the jump into the A. A photo caught at a dealer meeting in Barcelona last year makes us pretty sure it will be introduced at the Frankfurt Motor Show in September this year. Until then, there are spy shots to peruse.

Mercedes-Benz Vision Tokyo concept shows us our lazy future

The first autonomous vehicles to hit the road will likely look much the same as the ones we drive currently. But as self-driving technology evolves, so too will the shape of the vehicles themselves. And this is what Mercedes figures that future could look like. The Vision Tokyo concept, so named for the show now ongoing at which it's been unveiled this morning, is an odd yet forward-looking shape, rendered in Alubeam silver and glowing blue. Power comes from a hybrid hydrogen fuel cell and inductive electric charging system that give it a theoretical zero-emissions range of over 600 miles. One look at the lozenge-like shape should tell you that the design is all about the interior space. The driving station – should it be needed – offers a clean dashboard with HUD-only instruments and a central driving position with unobstructed view through the wraparound windscreen. The cabin is clearly focused, however, on the lounging occupants more than on the driver. Accessed via a single, giant gullwing hangar door, the approach is closer to that of a mobile lounge space than a traditional automotive interior, with a wraparound sofa, some manner of high-tech 3D game projected in the middle, and a wide infotainment screen on the inside of the door. The concept clearly foretells of a different future – one that demands less of the driver and offers more relaxed comfort. So while the driver within us grows concerned at his numbered days, the rest can't help but be strangely intrigued.
