2008 Mercedes-Benz CLK 63 AMG Black Series review

Mercedes-Benz CLK 63 AMG Black Series review:

The new CLK 63 AMG Black Series is based on the Official F1 Safety Car, the high-performance AMG vehicle that has been providing Formula One safety since 2006. The coupe, optimized for the racing circuit, is powered by an AMG 6.3-liter V8 with its performance boosted to 500 bhp and 470 lb-ft of torque. Top-rank handling is assured by the sophisticated AMG threaded suspension with 19-inch AMG forged wheels, new steering and the generously dimensioned AMG high-performance brake system with its composite disks. Visually, too, the CLK 63 AMG Black Series clearly shows its descent from the Official F1 Safety Car: its striking front apron with large cooling intakes, flared wheel arches, diffusor-type rear apron and carbon-fiber airflow breakaway edge, all demonstrate the car’s sporting pedigree.

The new CLK 63 AMG Black Series is technically and visually oriented towards the Official F1 Safety Car and thus addresses all sports-car enthusiasts who value high competitiveness. An output upgraded by 25 bhp accelerates the CLK 63 AMG Black Series from zero to 60 mph in 4.1 seconds, a few tenths of a second faster than the standard model with 475 bhp. The top speed is electronically limited to 186 mph (300 km/h).

Redesigned Intake and Exhaust Systems

Mercedes-AMG engineers achieved the increase in power by completely redesigning the intake and exhaust systems. The high-revving, naturally-aspirated AMG engine, with its 6208 cc displacement, gets its fresh air via larger-dimensioned intake ducts. The new AMG sports exhaust system with full-length twin pipes stands out with its unmistakable, pleasant AMG V8 sound. Together with a newly calibrated engine control unit, these measures ensure not only efficient load change behavior, but also let this eight-cylinder unit respond to the accelerator with even greater alacrity.

Power is transmitted through the AMG SPEEDSHIFT 7G-TRONIC. Compared to the standard CLK 63 AMG, the rear-axle ratio of the pur sang special series has been made about six percent shorter – to confer even more agility in acceleration in all speed ranges. For maximum sporting dynamics, the transmission has only the “M” and “S” driving programs; the comfort-oriented “C” is deleted. The driver can switch between the seven gears by using the AMG aluminum shift paddles on the steering wheel, while an indicator in the instrument cluster shows the gear selected at any given time.

Racing Inspiration
The visual appearance of the CLK 63 AMG Black Series shows its racing inspiration. The redesigned front end is descended 1:1 from the Official F1 Safety Car, and its generously dimensioned cooling-air intakes hint at the sophisticated cooling measures. For greater stamina under extreme operating conditions, a larger main radiator and an optimized power steering cooler, as well as an additional transmission cooler are built into the left front wheel arch.

The front fenders are made of high-strength and yet lightweight carbon-fiber composite material. On their flank, a “6.3 AMG” badge hints at the exceptional power of the naturally-aspirated V8. Redesigned side skirts extend to the broad rear fenders, which are in turn connected by a newly developed rear apron. The components taken over from the Official F1 Safety Car include not only the carbon diffusor fins and the integrated chromed dual tailpipes of the AMG sports exhaust system, but also a cooler for the heavily stressed rear axle.
