Vauxhall wins fuel economy shootout... with 6.2-liter VXR8

It's not out of the question to think that Vauxhall could win a shootout for the best fuel economy. But you'd figure the honors would be taken by something like the Ampera plug-in hybrid or one of its EcoFlex models, not the VXR8 muscle sedan, what with its huge 6.2-liter V8 engine. But it's precisely the VXR8 that took the prize at the end of the day. The Fleet World MPG Marathon doesn't just measure overall fuel economy, but how much of an improvement over its combined city/highway rating they can eke out of a given car.
