2005 Dodge Magnum R/T

The 2005 Dodge Magnum R/T is the new shape of American muscle, celebrating what American muscle cars were in the past, but with a design and packaging configuration that charges into the future. The legendary engine that powered Dodges muscle cars of the 1960s has been re-engineered and reborn as a modern, high-performance, fuel-efficient and durable werplant known as the all-new 5.7-liter HEMI® V-8 engine.


The Dodge Magnum R/T's 5.7-liter HEMI V-8 engine features 340 hp at 5000 rpm and 390 lb.-ft. of torque at 4000 rpm, the Dodge Magnum R/T can go from zero to 60 mph in just 6.3 seconds. The new HEMI engine has been engineered to deliver outstanding performance, while also delivering minimal noise, vibration and harshness, maximum smoothness and low emissions. The Chrysler Groups first five-speed automatic transmission for passenger cars is standard with the 5.7-liter HEMI V-8 equipped Magnum vehicles. It provides a full range of transmission performance to match a great variety of driving styles, situations and road conditions. Fully adaptive electronic control of all shifting makes the powertrain feel responsive without harshness.


Besides the HEMI engine, rear-wheel drive performance also returns to Dodge after more than 30 years with the 2005 Dodge Magnum R/T. Proven Daimler Chrysler technologies such as Electronic Stability Program (ESP), All-speed Traction Control and four-wheel anti-lock brakes control rear-wheel drive vehicles in a way transparent to the driver for all-surface and all-weather driving confidence.
