Mercedes-Benz has redesigned its largest and most luxurious coupe and renamed it the S-class coupe.
The coupe will debut at next month's Geneva auto show and will go on sale this fall in the United States.
It has new technical features, a fresh design and different proportions from the current coupe version of the S class -- called the CL.
Compared with the outgoing CL, the 2015 S-class coupe is about 1.5 inches lower with styling lines that are more sculpted and flowing. It has a bigger and wider grille and a wider panoramic roof that tints from light to dark with the flip of a switch.
The wheelbase is unchanged from the CL's 116 inches, but the car is more than 2 inches shorter at 198 inches. It is 1 inch wider than the CL -- at 75 inches, while the height is unchanged at 56 inches.
"The large coupe has always been the supreme pinnacle of our model range, and that's why it's now called the S class again," said Ola Kaellenius, Mercedes' global head of sales and marketing.
The CL has never been a big seller but has been a tour de force of technology. Mercedes is adding technology on the new two-door, including an optional head-up display. But the most advanced new feature is what Mercedes calls active curve tilting.
"The vehicle leans into bends much like a motorcyclist, thereby reducing the lateral acceleration acting on the vehicle's occupants," said Thomas Weber, Mercedes' head of r&d.
Initially, the car will be sold in the United States as the S550 coupe with all-wheel drive and a 4.7-liter biturbo V-8 that makes 449 hp.
The S-class coupe will compete with the Maserati GranTurismo and the upper end of the growing number of luxury vehicles with coupelike styling, including the Audi A7/S7 and BMW's 6 series and 6-series Gran Coupe.
U.S. sales of the current CL, which debuted in 2006, fell to 476 units last year, from 723 in 2012 and a high of 3,672 in 2007.
