In Europe only very few people buy a gasoline powered SUV (or big car, except for sporty ones), majority of them buying Porsche Cayenne.
Real MPG are very different from published, also because traffic conditions in EU roads don't allow a constant-speed drive as usual in US highways. Here is more a stop-and-go drive...
Real high performance cars are also sold with diesel engines, like latest BMWs and MBs
That's because (I owned a gas 3.0 Lexus RX350) that real medium mpg is (considering mixed commuting use) around 26 mpg with the JGC and 13/14 with a gas 3.0 engine.
Gas cars here are small city cars for the majority.
Diesel fuel cost less than gas, too. Here in Italy we probably get the most expensive price in Europe: at today change rate, diesel is $8 per gallon and gas is $8,5.
So there is no choice other than diesel.
Furthermore, drive is real more enjoying: the max torque at very low RPM gives you the full power of the engine immediately, at the first light press of throttle pedal, giving you the sensation of a hand pushing you on the back, while with a gas car you need to raise RPM very much to get full power, and this happens very rarely due to traffic and the way drivers usually behave.
When I had the Lexus, it was very annoying to perceive the lacking-power sensation at low throttle, than wait the lag for gear down.
Really another ride...
