2005 Charting the Changes Mercedes-Benz Mercedes-Benz
October 2004
Mercedes-Benz is flooding the zone with new models and engines. Heading the list is the SLR McLaren supercar, with its carbon-fiber monocoque chassis, ceramic disc brakes, 617-hp engine, and equally stunning price of $452,500. On the other end of the scale is the latest generation of Mercedes entry-level C-class sedan, coupe, and wagon family, which includes the C55 AMG and its hand-built
362-hp V-8. Also brand-new is the SLK350, a retractable hardtop roadster that comes with a 268-hp, 3.5-liter V-6 and a choice of six-speed manual or seven-speed automatic transmissions. The SL65 AMG and the CL65 AMG are both powered by a 6.0-liter twin-turbo V-12 that puts out an eye-popping 604 horses and 738 pound-feet of torque [see Technical Highlight below], and the SLK55 AMG has a 362-hp V-8. The boxy G-class SUV also gets an AMG model, the G55, which is powered by a supercharged 5.5-liter V-8 rated at 469 horsepower and 516 pound-feet of torque. The CLS500 four-door sedan debuts with a 302-hp, 5.0-liter V-8 and seven-speed automatic. And the E-class adds the E320 CDI, which is powered by a diesel engine that delivers 27 mpg city and 37 highway.
Unchanged: CLK-class, M-class.
Dead: C32 AMG, C230K, SLK230 Kompressor, SLK320, CL55 AMG, SL55 AMG, SLK32 AMG.
Future: The C230K will be replaced by a new B-class, which is based on the company's diminutive European A-class platform. Also expect a redesigned, bigger S-class sedan. Next year, the Alabama plant cranks up for the second-generation M-class, the next G-class, and an all-new R-class range of SUVs coming from the same platform. AMG is also preparing its version of the CLS500 the CLS65 which will share its 604-hp V-12 with the CL65 and SL65 and carry a six-figure price.
TECHNICAL HIGHLIGHT: Mercedes let loose its performance department, AMG, on the 5.5-liter twin-turbo V-12, and the result is an utterly fantastic powerplant. With a bump in bore from 82.0 to 82.6mm and a stroke increase from 87.0 to 93.0mm, AMG increased displacement to 6.0 liters. It also significantly raised boost pressure from 14.5 psi to 21.8. Although the SOHC twin-spark-plug, three-valve-per-cylinder arrangement remains, horsepower jumps from an already ludicrous 493 to an astounding 604. The torque numbers are even crazierpound-feet, up from 590. A Ferrari Enzo has 650 horsepower and a piddling 485 pound-feet. In fact, the uprated V-12 is capable of developing an additional 150 pound-feet of torque, but the five-speed automatic wouldn't be able to handle it.
