Mercedes-Benz C450 AMG Sport goes official with 362 bhp
Mercedes-Benz has introduced the C450 AMG Sport in Detroit at 2015 NAIAS.
This new version is positioned right below the fully-fledged C63 AMG and makes use of a twin-turbo V6 3.0-liter engine which has received a series of upgrades, including an increase in turbo pressure. Output stands at 362 bhp (270 kW) at 5,500 rpm and 382 lb-ft (517 Nm) of torque available between 2,000 rpm and 4,200 rpm.
Output is channeled to a 4MATIC all-wheel drive system through a revised 7G-TRONIC seven-speed automatic gearbox which enables the sedan to hit 62 mph (100 km/h) in 4.9 seconds whereas the wagon is 0.1s slower. Both body styles have an electronically-limited top speed of 155 mph (250 km/h).
Aside from the extra oomph, the C450 models also inherit some of the goodies from the range-topping C63, such as the updated front pull rods, adjustable dampers, tweaked front axle carrier and firmer springs. In addition, the car also gets new load bearing joints, extra negative camber and revised steering knuckles while the 4MATIC system has been modified to deliver the power in a 33:67 percent ratio.
The Mercedes-Benz C450 AMG Sport rides on 18-inch alloy wheels wrapped around in 225/45 front & 245/40 rear tires, with stopping power coming from 360mm front & 320mm rear ventilated steel discs that have grey calipers. Visual changes are limited to a tweaked front bumper with bigger cooling ducts, black side mirrors, updated front grille, darkened chrome exhaust pipes and a subtle boot lid spoiler for the sedan whereas the wagon gets a tailgate-attached spoiler element.
Changes on the inside are minimum but we should mention the flat-bottomed steering wheel, red seatbelts, sport seats, red stitching, alloy pedals and other minor tweaks.
Sales of the C450 AMG Sport are programmed to kick off in the following months.
