Under the scooped and vented hood of the Dodge Caliber SRT-4 is a 2.4 liter turbocharged engine with enough oomph to make sure that you can feel the torque steer. The motor is rated at 285 HP and 265 lb-ft of torque with a 6300 RPM redline, about right for a stroked 4 cylinder. Good enough to send the Caliber down the 1320 in only 14.4 seconds at 103 MPH. While manufacturers have a tendency to fib about output, Dodge traditionally underrates their performance machines, so I was very impressed to find out that Edmunds brought a Caliber SRT-4 to a dyno in southern California where they recorded a 281 HP pull. That’s at the wheels. Go Dodge!

The SRT-4 is powered by what Dodge is calling their World Engine. The power plant is actually a product of the Global Engine Manufacturing Association. Just like the old days of Diamond Star Motors when you could find a 4G63 under the hood of just about anything from Mitsubishi, Chrysler and the now defunct Eagle brand; the GEMA 4 cylinder architecture is being shared by Chrysler, Mitsubishi and the new kids on the block Hyundai.

Although the GEMA engines share the same block, everything else is customized to the manufacturer’s specifications. That is why the SRT-4 application comes with variable valve timing on the intake and exhaust side for increased performance and efficiency, and a Mitsubishi sourced TD04 turbocharger that makes around 13 psi of boost at wide open throttle.

Gears are shifted through a 6 speed Getrag manual transmission, no flappy paddles here; just a good old clutch pedal and shifter give the driver full control of up and downshifts. The German transmission manufacturers have been the choice for high-performance applications for years. Examples can be found in cars like the twin turbo Toyota Supra, R-34 Nissan Skyline GT-R, BMW’s M cars and the Porsche 911 Turbo. By choosing Getrag, Dodge has placed the Caliber SRT-4 in a class of well proven speed machines.

The Caliber rides on a Macpherson strut suspension up front and a multi-link setup in the rear. Brining the SRT-4 from 70-0 MPH in only 175 feet are a pair of hard working 13.4 inch brake rotors combined with a set of bright red two piston calipers sourced from the Charger Police Pack.

If it makes 281hp at the wheels, its actually slow.
