A standard Ford Focus RS that you get straight from the factory comes with a 350 horsepower (260 kilowatts) turbocharged engine and an all-wheel drive system. That is already quite fast for a Ford Focus to begin with, but there are just some people who want more. In this case, we are referring to UK-based tuner Mountune. But instead of complaining that the car is not powerful enough, they introduced an M400 upgrade for the said model instead.
But before we get into that, let us first talk about the upgrade that the company introduced last August. Ford gave the Focus RS a little push in terms of power, by increasing its output from 350 horsepower (260 kilowatts) and 350 pound-feet (474 Newton metres) of torque to 375 horsepower (276 kW) and 376 pound-feet (510 Nm). This was made possible, thanks to the custom air filter, the air re-circulation valve, and the new ECU. Now, the new upgrade can even push the 2.3 liter EcoBoost engine to an extra 25 horses (18 kW).
Going back to what I mentioned earlier, Mountune can unlock the Ford Focus RS’ power so it can achieve 400 horsepower (298 kilowatts) and 413 pound-feet (560 Newton-metres) of torque. This is after they add a high-flow induction kit, a new turbo re-circulation valve, a high-flow hard pipe, and a high-performance alloy intercooler, and an upgraded ECU. All these upgrades have their own roles to play in improving the car’s performance.
With a boosted engine and Mountune’s go-fast package, the Focus RS will be able to perform better in terms of quarter-mile times, 0-60 sprint, and straight line speed, but we do not have numbers to prove this just yet. What we do know is that with the M375 upgrade, the Focus RS will be 0.2 second faster while doing the 0-60 mile per hour sprint, while continuing on to a top speed of 165 miles per hour (266 kilometers per hour).
The English tuner will ask for £899 (or $1,170) for the M375 kit. Currently, it is only available in the UK and European markets. As for the newest M400 kit, it will cost you a bit more with a price tag of £3,000 ($3,905) on top of your brand new car.
Now the question is, would you spend an extra thousand or three for additional power and an improved performance? If this is what you want then there’s no time to waste as we’re sure the people at Mountune would be more than willing to give your car the upgrade it deserves.
