What is it?
The FQ-400 is the fastest, most powerful version of the Evo X, and a return for a name last seen on the Evo VIII. This time we have 403bhp, 387lb ft, an electronically limited 155mph top speed, and 0-62mph in 3.8seconds. Oh yes, and a price tag to match.
What’s it like?
In the scheme of things an extra 44bhp doesn’t seem like a massive jump from the already pretty poky FQ-360 (actually 359bhp), being only a 12 per cent increase. The torque boost (24 lb ft or 7 per cent) even less so. But as an experience, or more accurately, an event, the FQ-400 is so much more exciting than these numbers suggest.
Partly because of considerable extra pace, the reduced 0-62mph time undersells how much keener the FQ-400 responds, thanks to a revised low friction turbocharger.
The real transformation though, is in the character. When the Evo X first arrived, we were impressed with its newfound flexibility, but found the new 4B11 engine a touch anodyne - an accusation you could never level at the FQ-400. Given a specific output topping 200bhp/litre, that it is still flexible at low revs is impressive. This is no FQ-400 of old. From 2000rpm it is already pulling strongly, at 3000rpm it feels mighty, and at 5000rpm stupendously quick.
