In line with other recent new Mercedes-Benz models, all engines made available on the facelifted CLS comply with EU6 emission standards, including the four-cylinder diesels which receive urea exhaust treatment technology. New to the line-up is the CLS220 BlueTec. It supplants the CLS250 BlueTec as the entry-level model, with a turbocharged 2.1-litre four-cylinder common rail diesel engine producing 168bhp and 295lb ft of torque.
Joining the new CLS220 BlueTec in the UK line-up will be a revised CLS350 BlueTec, also running urea-injection exhaust treatment. Its turbocharged 3.0-litre V6 common rail diesel engine is down by 7bhp at 254bhp but retains the same stout 457lb ft torque loading as before.
The existing CLS350 CGI has been replaced by the more powerful CLS400, which runs a twin-turbocharged 3.0-litre V6 direct-injection developing 26bhp and 60lb ft more than the naturally aspirated 3.5-litre V6 direct-injection petrol engine used in its predecessor at 328bhp and 354lb ft of torque.
Continuing at the top of the line-up is the CLS63 AMG. Its twin-turbocharged 5.5-litre V8 now comes in just one state of tune equal to that of the earlier Performance Package option, with 549bhp and 590lb ft of torque. Left-hand-drive markets receive an even more powerful 4Matic variant punching out 577bhp and the same 590lb ft. But in a move mirroring that of the facelifted E-class, it won’t be sold in the UK owing to Mercedes-Benz’s decision not to engineer it in right-hand-drive form.
In a further change, the facelifted CLS receives a nine-speed automatic transmission as standard in all but the range-topping CLS63 AMG model. The so-called 9G-Tronic unit, which uses a steering wheel-mounted shift stalk to free up space at the base of the centre console, replaces the earlier seven-speed automatic, the 7G-Tronic.
The CLS63 AMG continues with AMG’s seven-speed SpeedShift transmission. As fitted to the outgoing model, it forgoes a conventional torque converter for an automatically operated clutch for faster shift times and added performance potential.
As part efforts to enhance its reputation for leading safety technology, Mercedes-Benz has provided the facelifted CLS with a number of new features. Standard fit features now include Collision Prevention Assist Plus, which automatically applies the brakes when an imminent impact is detected.
Among a long list of options are the new Multibeam LED headlamps. Claimed to outperform the latest laser lights being touted by Audi and BMW, they use a stereo camera mounted within the windscreen to detect on-coming traffic and automatically adjust 24 individual LED projectors so as not to dazzle other motorists. Each LED can be dimmed in no less than 255 stages, allowing what Mercedes-Benz describes as unrivalled broad and bright illumination of the road surface and road periphery.
Prices for the CLS coupe start at £46,500 for the C220 BlueTec diesel, rising to £86,500 for a top-spec CLS63 AMG. Meanwhile the CLS Shooting Brake costs from £48,080 to £87,000.
