Jaguar may be in no rush to bring diesel variants to the United States for anything more than a cross-country demo run. But overseas the marque's oil-burning selection keeps growing. The XF is already available in its home market with a 190-horsepower 2.2-liter diesel four, not to mention a 3.0-liter diesel V6 with 240 or 275 horsepower. But if those weren't frugal enough, Jaguar has now introduced an even more cost-effective alternative.
The Jaguar XF lives in very competitive segment alongside the BMW 5 series, Mercedes-Benz E-Class and Audi A6. All three of those cars offer something Jaguar does not: a four-cylinder diesel engine. This is a curious situation, since 80 percent of all 5 series sales are the four-cylinder 520d model in Jaguar's home market in the UK.
