This is our first glimpse of Subaru's long-awaited flat-four diesel engine
8 February 2007

It isn't quite as exciting as your average Subaru picture, which generally involves an Impreza at full pelt, but this is our first glimpse of Subaru's long-awaited flat-four diesel engine.

The new engine, which will be unveiled at the Geneva motor show in March, will be the world’s first horizontally opposed turbodiesel engine. Like Porsche, Subaru uses flat 'boxer' engines because they can be made more compact than normal upright engine, and help keep a car's centre of gravity low. The new engine will first be used in the Legacy from 2008.

    Jaguar’s second SUV faces up to the Audi Q3, BMW X1 and Mercedes-Benz GLA. Tough task, so is the E-Pace up to it?

    Not the driver’s car many would hope from any car wearing the Jaguar badge, but the E-Pace is an attractive and interesting addition to the compact premium SUV ranks
  • Subaru Impreza

    The fifth-generation Subaru Impreza is much improved from top to bottom, but a poor engine and gearbox keep it trailing in this competitive class

    We get a first taste of Ford’s poshest Fiesta in turbocharged diesel form

    Seat is on a roll but can the Arona, its new junior SUV, cut it in such an ultra-competitive class?
