Why do I care about a luxury Toyota? Well, because its powered by a 5.0 Litre V8 (2UR-FSE) engine that develops 420bhp (at 5800rpm) and 550Nm of torque (at 3800rpm). No word on 0-100 times yet, but it should be fast! The IS500 is reportedly 4665x1820x1435mm with a 2730mm wheelbase and weighs 1685kg.
