Diesel, manual wagon – pick two. Jaguar just missed the Holy Trinity by offering their new XF Sportbrake with two diesel engines; a 2.2L 4-cylinder or a 3.0L V6 coupled to an 8-speed automatic gearbox. The Sportbrake only weighs 150 lbs more than the XF sedan.
Cargo room is 19/58 cubic feet with the seats up or down, roughly on par with the Cadillac CTS Sport Wagon, the Mercedes Benz E-Class and the Audi Q5. American sales haven’t been confirmed yet – it would be surprising if they did happen – but the U.S.A would need some kind of gasoline mill, likely a V8, if the Sportbrake were to be sold here.
