The 335d makes its maximum torque figure of 580 Nm, or 427.7 lb-ft, at just 1750 rpm. That peak hits at less than 1000 rpm off idle. By comparison, the E90/E92 M3 makes its maximum torque of only ...

If those numbers are true, it means the car has 74 HP and 100 Nm (74 lb-ft) of torque more over the standard 335i. Also, the 0-100 km/h (0-62 mph) was improved by half a second.

Obviously, the diesel’s strong point is high torque, and the 335d is no exception. It produces 265 horsepower and 425 pound-feet of torque.

On the other hand, we have a BMW E92 335i that, in stock guise, makes 306 HP and 295 lb-ft (400 Nm) of torque. However, according to the uploader, the car in question has had a JB4 tune installed ...

The 335d's torque generator is a turbocharged and intercooled, DOHC 24-valve 3.0-liter all-aluminum inline-six. We've seen this engine in the Euro-spec 330d [September 2006].

The 335d's engine may be low-revving (as you can see from the image, the redline is 5,000 RPM), but that's fine with us because it creates a mountain of torque at a relatively low RPM.

With the 335d, BMW has proved that diesels can not only be good alternatives, but great alternatives. Let me sum this up for you: The 335d is a 3 Series BMW with 425 ft-lbs of torque, improved ...

Perhaps of most interest to American drivers is the upcoming 335d model. The 335d will hit the streets of America this fall with a 3.0L six cylinder turbodiesel rated at 265hp and 425lb-ft of torque.
