THE XR6 was something of a revelation from the start. Its performance was close to the XR8, and it had a better on-road balance which made it feel lighter and livelier. The other factor was the price difference which made the less expensive XR6 seem like a good buy against the XR8. Against that, there's nothing like the rumble and feel of a V8, so go that way if that's what you'd like. As for fuel consumption, it depends on whether you're a lead-foot or not. Ford didn't publish fuel consumption figures for their sporty cars, but I would expect around 13 litres/100km from the XR8.
