Staring blankly into the middle-distance, you exhale slowly, wondering when your heart palpitations will stop - then you turn the engine off.
That's the standard reaction after driving the FQ-360 in anger for the first time.
The FQ-360 is the most ballistic version yet of the Lancer Evo. For £8000 more than the entry-level FQ-300, you get an extra 63bhp (up to a thundering 354bhp), a performance exhaust, carbonfibre interior and exterior trim, and leather/suede seats.
It doesn't sound like much for the money, but the result is one of the fastest cars for getting from over here to over there - no matter what the price.
It's as shockingly rapid around corners as it is in a straight line, the steering lets you know exactly what the tyres are up to, and the brakes stop you quicker than a windscreen stops a fly. Driving this car is a blast.
Downsides are a small boot, a steering wheel that doesn't adjust in and out, and that it's a tricky car to drive at manoeuvring speeds. Oh, and you'll get around 175 miles from a tank of fuel.
Still, having to stop at a petrol station so often gives your heart a chance to settle down.
