Munich reveals fast ‘M’ version of its X4 SUV with a newly developed turbocharged six-cylinder producing 355bhp and 343lb ft
11 January 2016

BMW has launched a new M-Performance model in the form of a hot X4 M40i. The SUV has made its public debut at today’s Detroit motor show and will go on sale in the UK during the first quarter of 2016.

The BMW X4 M40i sits at the top of the BMW X4 line-up. Although the UK price has yet to be determined, it is likely to be pitched above the existing £49,295 X4 xdrive35d M Sport, according to highly placed BMW sources.

The Munich company vows that the X4 M40i will “set the benchmark in its segment for outstanding driving dynamics”.

Power comes from a newly developed M Performance TwinPower Turbo six-cylinder in-line petrol engine. The three-litre unit produces 355bhp between 5800-6000rpm and generates peak torque of 343lb ft. The BMW X4 M40i covers the 0-62mph sprint in 4.9sec and can achieve a restricted top speed of 155mph.

By comparison, the turbocharged 3.0-litre six-cylinder diesel powered X4 xDrive35d M Sport hits 62mph in 5.2sec, with a top speed of 154mph.

Combined fuel consumption for the X4 M40i is put at 32.9mpg according to BMW’s own claimed figures and CO2 emissions are 199g/km. 

The BMW X4 M40i’s sports suspension is fitted with uprated springs and anti-toll bars and also has increased camber on the front axle, M Performance specifications for the adaptive dampers and the BMW xDrive all-wheel-drive system with rear-wheel-drive characteristics.

The exterior gets M Performance adornments such as bespoke colour accents on the front of the car, 20in double-spoke light-alloy wheels and a sports exhaust system with valve control and black chrome tailpipes.

The interior has a leather steering wheel,  M gearshift lever, sport seats and model-specific door sill plates.

The performance version of the X4 - which will compete against the Porsche Macan Turbo and Audi RS Q3 and Mercedes GLC  - was first seen testing in 2014, as our spy photographs show.

Our Verdict

We suspect the reason for the BMW X4's creation is because of the Porsche Macan

The X6 is a showroom hit. Does its smaller brother deserve to be?

Few cars were criticised over their looks more than BMW X6. It has already spawned X4. Now just wait for Audi, Porsche and Mercedes versions.

Probably much better car than given credit for, mainly due to the dislike of the whole concept by motoring mags/some online commenters, but why would you bother with this when the standard X3 is every bit as good to drive, roomier, cheaper and looks better?

19 June 2015
There's a couple of these around here now, they look terrible.

19 June 2015
I presume a M340i/M440i will be on the cards too? If that was the case, the advantage over the M135i/M235i wouldn't be great performance wise.

19 June 2015
I guess the Porsche,Mercedes,BMW battle rages on?,but,aren't there enough choices?

What happened to the days of the 3,5,6,7 and 8 series.... Stick to the basics instead of producing ugly crap... I'm off to buy a Merc.
