I would give my eye teeth for a diesel. There is lots of talk and rumours of one, perhaps in '09-'10 they will, but for now stuck with the I5 or the new alpha V8, which gives you 295 horse as opposed to the 235 with the I5.. Im sure that fuel economy will take a hit with the larger motor, I get about 15-16mpgh city 20-22MPGH highway.
