Jaguar Swaps V8 For Super V6 In XF And XJ, 8-Speed Auto For All

Jaguar may be focused on its upcoming F-Type roadster, but the brand's large XF sedan and XJ limo are hardly going unloved.

This week, both have picked up new engines, and all transmissions have been upgraded to ZF's eight-speed automatic unit.

In both cars, Jaguar's 283kW/515Nm naturally-aspirated V8 engine has been swapped for a brand-new supercharged 3.0 litre V6.

Announced in April, the new super-six is available in two states of tune: 250kW/450Nm and 280kW/460Nm. It is the former that will feature here, replacing the more powerful but thirstier V8. (The latter will drive the F-Type.)

The fuel consumption improvements are nothing to be sneezed at: while the V8 listed 11.3 l/100km for the big XJ, Jaguar says the new engine will bring that number down to 9.4 l/100km.

Those savings are also thanks to a stop/start system, and the addition of ZF's eight-speed automatic transmission, replacing the existing six-speed unit in both the XJ and XF.
