Thread: D2 V8?

Both engines are 3950cc (close enough) but I think the D2 was called a 4.0 to match the Jeeps 4.0 engine.

The D2a refers to the 03/04 model years. The head lights were updated & CDL re-introduced.

Thanks, were there any changes to power and torque? Are the electronics the same etc?
Which is more reliable? and economical?

The D2 uses the later Bosch injection with a different manifold set up. I'm not sure on the power & torque figures but the 4.0 is a lot more responsive than the earlier engine.

There are more electronics on the D2 but I would have to say they're both reliable enough. There's the odd sensor that might play up as with any electronic injection system.

Not too sure on economy but the later engine should be better in that regard. They are heavy cars though & neither would not be classed as economical.
