The revised version of the current-generation Mercedes S-Class has been caught testing many times, including extreme cold-weather conditions. However, the prototype caught today by our spy photographers gives us the best look at the new S-Class to date, as it is almost completely void of all camouflage and our photographers got up close and personal with the car.

The 2014 S-Class will borrow design elements from the F800 Style Concept, making it sharper and a little bit more aggressive. Also, we expect to see the same one-piece headlamps with LED daytime running lights we have seen in the new E-Class->ke373.

Under the hood, Mercedes->ke187 will likely place a revised version of the current engine lineup, which includes a Twin-turbocharged, 4.7-liter V-8 engine with 429 horsepower; a 510-horsepower twin-turbo 5.5-liter V-12; and an AMG twin-turbo 5.5-liter V-8 delivering somewhere between 536 and 550 horsepower.

Competitors

BMW 7-Series

The BMW 7-Series is the only German luxury sedan that already received a revision. It received updates to both the exterior and the interior, but just like with the A8, they were minimal and included new full-LED headlights, a prominent BMW kidney grille and a modified front apron.

For the North American market, the 7-Series is offered with a choice of three engines: a 3.0-liter, TwinPower Turbo inline 6-cylinder engine with 315 horsepower; a 445-horsepower 4.4-liter, V-8 engine; and a 6.0-liter V-12 engine delivering a total of 544 horsepower.

Audi A8

By the time the redesigned S-Class is put on sale, Audi will also offer an updated version of the A8 luxury sedan. Recent spy shots revealed the updated A8 will receive a redesigned front bumper, a new grille and new headlights. For the rear, new lights and an updated bumper will be all the revise A8 gets.

No updates have been announced under the hood, so U.S. customers will likely get to choose between a 333-horsepower, 3.0-liter TFSI V-6 engine; a 420-horsepower, 4.0-liter V-8; and a 6.3-liter W-12 that delivers an astonishing 500 horsepower.
