The Infinity FX is offered in two versions, the FX35 and the FX50, depending on the engine. The basic version gets a 3.5-litre V6 engine, while the other is powered by a 5.0-litre V8. Both have seven-speed automatic transmissions and all-wheel drive systems. The FX not only looks sporty, it sounds like it! The FX50 can be fitted with really nice and expensive 21-inch wheels. And its performances are quite something.
