Slow? Hardly. This new 3.0-liter V-6 (despite what the E320 designation might have you believe) is intercooled and turbocharged, with the exhaust-stream hamster wheel made more responsive with a variable-vane arrangement similar to what's used on the Porsche 911 Turbo. This steel-sleeved, aluminum-block engine makes 208 bhp and an axle-twisting 388 lb.-ft. of torque-the last stat nearly matching Mercedes' 5.5-liter gasoline V-8-on tap from 1600 to 2400 rpm.
