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:

2015 Mercedes-Benz GLA250 4Matic Quick Spin [w/video]

Certain expectations come with the name "Mercedes-Benz." We picture cars with luxuriously appointed interiors, fashionable exteriors, Autobahn-worthy performance, and a ride that delivers an optimal balance between agility and outright comfort. Expectations, though, are no friend to the GLA250. This is a car that is deeply confused as to its purpose in life – can it be a proper Mercedes-Benz while still being a reasonably priced, subcompact crossover? After a week behind the wheel, we believe the two are mutually exclusive. Driving Notes The exterior styling is similar to the not-for-America A-Class hatchback, with the only major differences found on the rear end. That means that even with its flashy 19-inch AMG wheels and sport body styling – more aggressive front and rear fascias – the GLA is a stylish piece. We might even call it cute. Considering our 4Matic model's reasonable $34,225 starting price, the interior treatment is both attractive and uses mostly quality finishes. The matte Satin Light Brown Poplar wood ($325) covers a large portion of the dash, while the real metal found on the air conditioning vents is elegant and handsome. There is a lot of plastic in the cabin: It's soft on the dash, and switches to a piano-black finish in spots, but the center console and door finishers don't feel like they came from the Mercedes parts bin. In general, the GLA's cabin feels roughly equal to that of the Audi Q3 and BMW X1 – nice, but a step lower than what we've come to expect from Mercedes. The two-piece, leather-lined seats look great, but even with standard 14-way adjustability, they lack support. The bottom cushion is very flat, and doesn't support the legs. For this author, that's a recipe for near-constant back pain. That said, the chairs do look good, especially in the brown of this test car. The GLA250, like a few other models in the Mercedes range, uses a 2.0-liter, turbocharged four-cylinder, delivering a weak 208 horsepower. It makes up for that shortcoming with 258 pound-feet of torque from 1,250 rpm to 4,000 rpm. On paper, this sounds good, but in the real world, the 2.0T's power is tough to access. That's due more to the shortcomings of the seven-speed dual-clutch automatic than the engine itself. With three modes – Eco, Sport, and Manual – we thought we'd find at least one that could serve up precise downshifts.

Mercedes calls CLA 'best launch in 20 years' as it warns dealers of tight supplies

It's still in the early going, but it's looking more and more like the 2014 Mercedes-Benz CLA is a verifiable home run for the German brand. According to a new report from Bloomberg, the new small car isn't just widening the sales gap between Mercedes and BMW, it's attracting a new, younger breed of customers into the brand's showrooms. But that early success is straining supplies of the turbocharged four-door.
Dealers have been warned that the first half of 2014 will see limited supplies for CLA, with a letter to dealers indicating that "tight inventories and low days supply" will exist from February through June, despite the car's Kecskemét, Hungary plant running at full tilt.
"This is our best launch in 20 years," said Steve Cannon, the US boss for Mercedes. "The CLA has been a phenomenal success right out of the gate." The numbers certainly support that. We reported in early October that Mercedes moved 2,300 CLAs in its first week on sale, and now Bloomberg is saying CLA sales were almost singlehandedly responsible for Benz's November sales gains. Mercedes' annual sales are up 14 percent through the November, and it's enjoying a healthy 7,600-car lead over BMW.
