Currently reading: New Ford Focus RS Mountune kits add power and tech

m400R takes power to 394bhp, boosts mid-range response and adds new functionality; m400X "takes performance to another level"

Ford tuning specialist Mountune has released two new performance upgrade packages for the Focus RS hot hatchback.

The Essex-based firm has had plenty of experience boosting the output of the hottest Ford Focus, and the new packages, dubbed m400R and m400X, supersede the widely available m400. 

The m400R, offered as a free upgrade to current m400 owners, takes power and torque to the same 394bhp and 414lb ft figures as the old package, but it also brings with it a number of calibration features, including a full-time launch control function, full-throttle gear changes, an adjustable rev limit and tailored valet and anti-theft modes.

The m400x includes the same software features but is said to take "the performance of the RS to another level". No additional power or torque output is listed over the m400R, but Mountune claims it "dramatically transforms" the car's pick-up, throttle response and mid-range by "substantially increasing the area under both power and torque curves". 

Both packs can be purchased from £595, but stock cars require hardware modifications including a new induction system, a larger intercooler, a three-inch downpipe and an upgraded 'cat-back' exhaust. That means the whole system will cost £3297 for first-time Mountune customers.

How's the RS viewed in the UK?

The Focus RS hit the USA with high expectations and much fanfare. The US market has often been ignored by Euro and Japanese manufacturers when it comes to 'hot' versions. However the RS's arrival has been lukewarm, with a consensus that the Type R is a better everyday driver, as is the Golf R. What's the take in the UK? (I trust you guys more),

. Not top Dog for sure here in the UK, certainly top five, Mercedes (A45AMG) and the Honda type-R are preferred weapon of choice, the Golf R needs replacing ,getting a bit old now, the Focus here is a modern delight, some with insane amounts of BHP. I guess where it went wrong is Ford didn’t develop the RS to keep ahead, and when Mercedes released the A45 AMG and just recently the A35 AMG FORD had nothing in the Locker to combat it, even Audi’s get more coverage, if I’m being kind the RS is a connoisseur Car, you accept it’s not top Dog but you like the Car.
