M - Mercedes' high-performance AMG division has released details of an interesting new variant on a few of the company's performance cars. The latter suggests the new Mercedes-AMG CLS 53 will feature an all-wheel drive system similar to what the E63 models have, but that's not really a surprise considering the CLS is essentially a more agile and upscale E-Class.
Mercedes-AMG has broadened its line-up with the addition of three new mild-hybrid models - the CLS53, E53 Coupé and E53 Cabriolet. Interiors get model-specific, exclusive appointments, luxurious materials, and other goodies. The interior boasts copper highlights, and black Nappa leather with copper contrast stitching which is also used on the instrument panel, door panels, piping, and elsewhere. The CLS53 also gets several color options, including macchiato beige and magma gray, black and Bengal red, and espresso brown and magma gray. All three models use a brand new 3.0-litre straight-six petrol engine, which is fitted with two turbochargers: a traditional exhaust gas charger, and a new 48V electric compressor, the latter a Mercedes first. He continued, "The basis for this is a contemporary drive configuration in the form of a six-cylinder inline engine with electric auxiliary compressor. the precision and the design focusing on driving dynamics are hallmark features of AMG". That high-zoot electrical system powers a separate electric intake compressor providing nearly no turbo lag, according to Mercedes, supplementing the conventional exhaust-gas turbocharger that's also fitted to the engine. Mercedes quotes a 4.3-second sprint to 60 miles per hour for the E53 Coupe while the CLS53 and E53 Cabriolet take 4.4 and 4.5 seconds to do the same, respectively.
The total system output is resting at 429 horsepower and 384 pound-feet of torque.
Retail inflation at 17-month high in Dec '17
US consumer prices rose in December, bolstering expectations that long-weak inflation is set to gain strength in the new year.... Annually, the report said, headline inflation rose 2.1%, slightly down from November's reading of 2.2%.
Mercedes claims its EQ Boost starter-alternator adds an additional 21 hp and 184 lb-ft of torque to the 53 models. The benefit of the system is the delivery of a performance vehicle with improved emissions and efficiency without any loss in sporty abilities. However, you'll also save fuel, the automaker says, since the EQ Boost system works with the car's 48V on-board electrical system. Although the technical specifications are still shrouded in mystery, we can at least see most of the exterior design and how it will be different compared to the lesser models of the CLS range. These cars also borrow the excellent driver assist technology from the flagship S-Class.
The fastback-styled CLS saloon, and the E-Class Coupe and Cabriolet will be the first models to wear the new badge. In line with Cars.com's long-standing ethics policy, editors and reviewers don't accept gifts or free trips from automakers.
