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.
But where the FQ-400 really shines is at higher revs; although peak power arrives at 6500rpm, the FQ-400 will rev to 8000rpm, and unlike the FQ-360 feels happy doing so.
Fuel injectors aside, Mitsubishi haven’t changed any of the engine internals, only the ECU, turbo, intercooler and exhaust, but these alone give a more frenzied angry top end.
It also sounds miles better than the regular FQs, thanks to that new exhaust, complete with a Murcielargo style huge central tailpipe. At idle there is a restless deep burble, which hardens under load and is accompanied by a whole host of whistles and whooshes from the turbo. You really get the sensation of sitting in a proper rally machine. On the over run it pops constantly, and if you come of the throttle sharply at higher revs it produces a full-on rally style rifle crack which is outrageously anti-social, but utterly brilliant.
If all of that sounds like a nightmare to drive, it isn’t. Mitsubishi has solved the regular Evo’s lazy throttle response from idle, and new Alcon six piston calibres improve the already very good brake feel
Lowered by 30mm and running a 15mm wider track, the FQ-400 is even more tightly controlled through the corners. It still steers brilliantly and the extra power means you’re able to better exploit the excellent chassis balance. New lighter wheels mean that despite the lowered ride the ride doesn’t suffer materially, and these come wrapped with even stickier Toyo Proxes R1Rs tyres.
As you would expect Mitsubishi has gone to town on the FQ-400 exterior. In addition to the exhaust, there’s an even more pronounced front splitter, a gurney strip on the spoiler, vented sills and ludicrous number of bonnet scoops. It is completely over the top, but then what do you expect from the maddest version of an already pretty mad car?
