Looking to spoil some of the new fourth-generation BMW M5's glory, Mercedes-Benz has issued its first official photographs of its upcoming CLS55 AMG -- before the base model of the M-B car has even hit the streets.
The high-performance CLS55 is set to be unveiled at this September's Paris auto show and is scheduled to go on sale next January in Europe for about E81,000.
The new super CLS is referred to by Mercedes as a coupe, but with four doors and conventional B-pillars it's really a sedan.
Based around the same mechanical package as the E55, the CLS55 has performance and features to match the new M5 -- the most powerful road-going BMW ever.
The CLS55 is powered by AMG's supercharged 5.5-liter V-8 engine, which delivers 476hp. The new M5 has a purpose-built gasoline 5.0-liter V-10 that delivers 507hp -- up 107hp on the outgoing model's 4.9-liter V-8 engine.
Mercedes claims 0-100kph acceleration in 4.7 seconds and a top speed limited to 250kph.
BMW says the M5 will hit 100kph in 4.7 seconds and reach its 155-mph top speed in 14.9 seconds.
With its speed-limiting chip removed, the new sedan will reach 330kph, BMW says. Company policy prohibits official modification.
