That was an interesting Top Gear show.  That engine is amazing.  Actually it
is the same disp at the gas engine, 4172cc, puts out the same 335Hp (but at
3750rpm!), but has a colossal 479 ft-lb of torque!  Even though the diesel
version weighs about 165 kgs more, it is rated at 25% better fuel mileage
with about 15% fewer CO2 emissions.  It also does 0-62 in 5.9 secs (vs 6.3
for the gas version).  Better acceleration, same top end, better fuel
mileage, fewer green house emissions...it does cost about 2% more...sounds
mighty attractive.
