The 3.0-litre has a compression ratio of 10.5:1, which is much higher than the 5.0-litre’s 9.5:1 ratio.Jaguar will also offer the 240hp 2.0-litre turbo four cylinder that is already available in the Range Rover Evoque.
Range Rover actually borrows the engine from Ford but in Jaguar’s application, it is rotated for longitudinal installation. I guess most Singaporean readers would be more interested in the four cylinder rather than the V6 from a road tax point of view.
As reviewed on the 21 Apr 12 edition of The Straits Times, Ford’s 2.0-litre turbo delivers power sweetly and smoothly right to the redline, with no hint of harshness and vibration.
Both engines will be mated to a ZF eight-speed transmission, which is also used by BMW, Audi, Chrysler, Rolls-Royce and Bentley. Jaguar also commented in the press release that the higher output version of the V6 will reside under the hood of a more powerful variant of the upcoming F-Type roadster when it hits the market some time in 2013.
The 2.0-litre turbo four would be a good base engine for the F-Type. In fact, it would make good business sense to equip the XF with the 2.0-litre turbo in order for it to compete against the BMW 520i/528i, which is powered by BMW’s 2.0-litre TwinPower Turbo.
