The new variant of the CLS range will arrive in European showrooms in November with two diesel and two petrol power units confirmed to be employed. These consist of the CLS250 CDI that produces 201hp and the CLS350 CDI that produces 261hp while petrol options will include the CLS350 with 302hp and the CLS500 producing 402hp.

One additional unit we can definitely expect is the twin-turbocharged 5.5-liter V-8 that will power the high performance CLS 63 AMG Shooting Brake. Rumors have stated it will generate around 518 hp (386kW / 525hp) and 700Nm (516lb-ft) of torque which should allow it accelerate from 0-100kph (0-62mph) in around 4.5 seconds before hitting an electronically limited top speed of 250kph (155mph).
