With more power, better fuel economy, and the world's first Blind Spot Intervention System, the all-new Infiniti M56 and M37 feature a 5.6-litre V8 engine and refined 3.7-litre V6 engine, respectively. The V6 power is up nine per cent to 330 hp, while V8 power is up almost 30 per cent to 420 hp. Yet amazingly, fuel efficiency has been reigned in by shaving off 1.7 L/100 km highway for the M56x and 0.8 L/100 km highway for the all-wheel drive M37x. The M line is also a showcase for Infiniti's new technologies such as Active Noise Control, Blind Spot Warning and Eco Pedal. The spacious, quiet cabin is ideal for tall people with a penchant for peace and quiet. The flowing wave exterior profile expresses Infiniti's design vision – energetic force, seductive lustre and spiritual precision. MSRP $52,400 (M37) and $66,200 (M56)
