BMW's facelifted M135i has more power, sharper looks and new technology. The previous version was a belter, so is this new one just as good?

Can a final facelift enhance the appeal of the rear-drive 1 Series?

    2015 BMW 1 Series 125d M Sport review

    Revised diesel 1 Series packs a solid punch but lacks the compelling nature required to merit its premium
18 March 2015

What is it?

The BMW M135i is an interesting proposition. Even BMW will tell you it’s not a ‘proper’ M car, but that doesn’t stop people peering round its rear end, checking the badge and the twin tailpipes and nodding sagely. M car or not, it’s forged its own path in people’s minds as a ‘proper’ car all the same.

Unbelievably, it has been a decade since the launch of the original 1 Series. So to counter Father Time, the second generation has received a nip and tuck.

Along with subtle styling updates it has more power and a host of new features for good measure. So is this latest depiction of the M135i still good to drive, and has it retained its power to impress the badge connoisseurs?

What's it like?

Slimmer headlights and a new aerodynamic M Sport front bumper create a more aggressive look that, to these eyes at least, is prettier at the same time. The rear also appears more distinguished thanks to new L-shaped LED tail-lights.

Inside it’s basically the same impressive interior as before, with a touch more panache thanks to chrome and gloss black detailing around the centre console.

Technology upgrades mean that adaptive LED headlights and cruise control are on the options list, as is a GPS-guided eight-speed automatic gearbox similar to that used by the Roll-Royce Wraith. BMW Connect is standard and comes with emergency assist. You can also add apps for live traffic reports, music streaming and a concierge service.

Right-hand drive versions still have slightly offset pedals, but otherwise the driving position remains faultless. There’s an oversupply of leg and head room, even if you're upwards of six feet tall, and that space is complemented by plenty of steering wheel reach.

This latest incarnation of the six-cylinder turbocharged engine has a touch more power – now 322bhp - and it’s as fabulous as ever. You can barely detect the signs of forced induction and it is delightfully smooth in its harmonics and power delivery. This wonderful linearity means it will pull from 1000rpm uphill in third as easily as it will eagerly blat around to its redline.

Our car had the six-speed manual gearbox, and although the theory is that it’s slightly slower than the automatic (0-62mph takes 5.1sec as opposed to 4.9sec), we think it's worth the trade in pace for the extra interaction. This is thanks to the lovely weighting and precision of the change, along with pedals that enable you to heel and toe with ease.

This was almost a requirement around our snaking Portuguese test route that was also a decent test for the M135i’s chassis. On the approach to a corner the brakes feel positive and progressive, and as you ease off them and begin turning in, the front end bites, which gives immediate confidence.

Mid-corner there’s a little lean before the body settles, and then it’s a case of exploiting that predictable engine map and the car’s innate traction to fire it out and on to the next kink. It's a process that you'll want to repeat over and over again.

However, the variable-ratio steering, despite being firmer than that of the standard 1 Series, is still a touch too light and urgent with its initial response, and there’s precious little feedback through the wheel.

Furthermore, hit a bump mid-bend with the M135i’s suspension under load and it has a disconcerting tendency to give a little skip sideways. This trait didn't cause any real dramas, but it sowed the mental seed that at full tilt it isn’t quite as tied down as it first appears.

That said, for a car with this level of performance, on the optional adaptive dampers the ride is relatively forgiving. Even stepping up the challenge by aiming at bigger potholes failed to make it feel crashy. Indeed, the only thing that was any bother was a slightly bouncy high-speed ride.

Should I buy one?

One of the things about the previous car was its amazing value considering the performance on offer. It's a shame, then, that BMW has now bumped the price up to £31,725 for the five-door we tried. Even so, bang for buck, the M135i is still an impressive proposition.

There are question marks over its steering and handling on the very limit, but otherwise it’s a difficult car to fault. It is comfortable and genuinely quick, but most importantly for this kind of car, if you stick it on the right road the M135i will stick a huge grin on your face in return.

Not many readers will have had the pleasure of the grandfather of this car - 2002 Tii , which remains in my soul and not just my heart as one of the best cars I ever owned. The original 1 series actually annoyed me - they missed all the pointers to a classic (of which BMW have so many to their name - and I also had the 3.0 Csi as another soulmate). But this little blighter brightened my day, and honestly, it is a long long long time since any BMW did that. It doesnt need the M expensive cost badging on it - they seem to have got it just right. Do I want one? No, but I will smile when I see one being driven properly :-)

Cruise control on the options this level !!!

To be honest, i think this type of car is all the performance you'll need,it goes like stink(you can only do what the Law says),it returns a decent mpg,has a low C0'2 for it's engine size,and if your a low annual miler,doesn't cost a lot to run.

I agree, it is a great car in that respect. It just misses out by looking so damn bad. Better than the previous one, but only just. Suppose, when you are having great fun behind the wheel, you don't have to look at it :D

BMW should be applauded for sticking with a normal round steering wheel and not following the trend for these idiotic flat bottomed items found in other cars. Sawn off wheels are so awkward in everyday driving where you have to actually turn the wheel more than a quarter of a turn in either direction.

I think this is a great car. It's still good value despite the price rise, and on the public roads you really can't use any more performance than this offers. And being a straight six it will sound great unlike the turbo charged 4 cylinder motors.
