Driven: BMW 125i M Sport

So: rubbish four-cylinder replacement for a much-loved straight six, or intriguing Golf GTI alternative?



To understand the existence of the BMW 125i M Sport - and to have a chance to embrace it - you need to accept the fact that naturally aspirated six-cylinder BMWs are near-as-dammit dead, especially in smaller BMWs. There's simply too much pressure from both the marketplace and legislators to bring down emissions and fuel consumption for the less tangible pleasures of a nice noise and a linear power delivery to survive.


So while you might (rightly) mourn the absence of a six-cylinder non-turbo engine from the 1 Series line-up, the presence of the 2.0-litre twin-scroll turbo four-cylinder in the nose of the 125i is most certainly not without merit. Its 228lb ft of torque is available all the way between 1,350 and 4,800rpm, giving the 1 Series the sort of low-to-mid-range brawn the old 130i, while the power delivery does manage to retain a fair amount of the revvy, zingy nature that made the old straight-sixes so alluring.

OK, we will admit that the sound isn't quite up there with an inline six, and there is a light tap-tap rattle at idle that is vaguely irritating (but given that a Golf GTI has more than a whiff of diesel about the noise it makes at idle, we'll forgive the 1 Series that one), but overall it's actually a pleasant-sounding car.

And, however much we wish it weren't so, cars in this market - performance-oriented but still everyday cars for people with limited resources - do need to provide ever-more in the way of fuel economy. So, with regret we're inclined to take the claimed 42.8mpg (about 35mpg in our time with it) over an extra couple of cylinders and a nicer noise.


We've already tried the bigger brother of this engine in the BMW Z4 and we know that it makes what is otherwise a distinctly average car palpably better. In the 1 Series, it makes what is an already thoroughly decent car into a borderline cracking one.

Throwing aside the question of looks (these things are of course subjective, but it is hard to love the styling of a 125i, even with the beefy M Sport addenda), the latest 1 series is a pretty good bet. The Interior is now up there with what you expect of a mini BMW, being well laid-out and reasonably well put together, while the packaging is also much better than it used to be, with a decent boot and space for four actual adult-sized people.

With the 125i M Sport you also get a chunky bumper, spoiler and side skirt combo, along with twin tailpipes and, inside, flashes of aluminium-esque trim and leather sports seats. In addition there are 18-inch wheels and beefier brakes, with natty M Sport calipers.


Previous 1ers have generally not been blessed with the most eager handling though and, although the latest generation is definitely more involving than its predecessors, the light steering has an occasionally tinge of vagueness to it the does the car no favours, especially on turn-in. Having said that, the car's RWD layout makes it naturally light on its feet, giving you the pleasing sense that the car pivots around the driver. The damping, so often a BMW bugbear on bumpy British roads is also far better than we feared - though we'd suggest you keep the adaptive suspension settings away from the sportiest of its four modes.

The 1 Series still isn't all that exciting dynamically, then, but that's in comparison with other BMWs; against its front- and four-wheel-drive rivals the advantages in agility of the rear wheels doing the driving and the fronts doing the steering are palpable.

In short, the 125i has a mini sports saloon feel to it that more conventional C segment hot hatch rivals could not hope to emulate, and the punchy, efficient engine combined with a well-weighted (if a teensy bit notchy) six-speed manual serve to highlight that.


BMW has played a canny game in its market positioning of the 125i, too. It might not have the terrier-like flingability of the most hardcore hot hatches such as the Renaultsport Megane, but it presents a more mature, subtle alternative to the fast hatch norm.

With the basic list price a small but significant notch below the Golf GTI (perhaps its closest conceptual rival; an everyday performance car with a mature, sensible edge) the 125i represents a genuine, unique and good-value alternative to a mainstream hot hatch.

And if you really need six-cylinder power from your 1 Series you can always wait (and save up for) the forthcoming M135i. Then again you could pop along to the PH classifieds and have a butcher's at previously loved 130is...

Can't believe that these do 0-60 in almost the same time as the old E34 M5 3.6!

Good to hear that they've sorted out the poor packaging of the old car. Otherwise it all sounds a bit... "dull but worthy".

Quite a low specific output for a turbocharged engine; I suspect the "remapping" crowd will have fun with it. smile

I can believe it. The E34 is ancient.

Looks like a genuine alternative to the Golf GTI, especially now they've sorted the interior space issue.

I had a go in the old 6-cylinder 125 Coupe - seemed a very taut little car and similar performance to an E46 330

Not as much go as a 130i but I prefer the looks of the Coupe to this one

I won't be chopping my 130i for one...

... On the other hand, the 135i could be awesome!

Are BMW not doing a 120i anymore?

The new range is slightly confusing. You can't get the 120d in M-Sport 3dr form either.

Ancient it may be, but it's still more solid and better put-together than many of these newer models.

Also better looking.

And the roads aren't littered with E34s either, compared to these 1 Series, A3s, Golfs, etc...

It does look a lot better in M Sport form than in standard trim. Same as the old one, hated the standard trim but could tolerate the M Sport. I bought one because of it being a decent car rather than the looks

Peak torque from 1350-4800rpm with peak HP coming in@5000rpm rofl It may as well be a diesel!

what do you mean more solid than many of the newer models? i'd bet all of them. the 535i was one very well screwed together package.

this new 1 series doesn't do it for me, but it has grown on me a bit; maybe it's the colour. when it was first unveiled i thought jesus wept that's hideous....now it's more "meh" which is a step forward i suppose.

sounds like it's a good drive though so should ensure the M135i will be a hoot.

turbo petrol gives similar curve shape to turbo diesel shock. the petrol will obviously rev higher but you seem to be comparing NA petrol to turbo diesel. the new turbo petrols give a huge band of torque; why i never understand why people say low down torque of diesel; in reality they mean the low down grunt of a turbocharged engine.

also - the peak torque band on the petrol is far wider than with a diesel, find a diesel car producing peak torque all the way up to 4800rpm!!

It's a shame really as the best thing about my 130i was the engine. When I bought it, there was no way I'd entertain a 4 cylinder model. And I feel the same today.

Only problem is that a M135i is only £1500 more (and 100+ hp more and 2 cylinders more) if you spec the M125i with leather, xenons and M-SPORT brakes(factory 4-pot calipers), which are all standard on the M135i and makes it a performance bargain IMO. It almost looks decent in 3-door too.

Thats a mapped 123d wink 430nm@2000rpm, it still has 430nm@4400 with peak HP holding on until 4600 where he seemingly backs off. This is with a car@272hp, if the car was tuned for economy and running ~220hp it would be much easier to prolong the torque all the way untill 5000rpm.

So yes, it might as well be a diesel!

Wasn't this done to death on the previous thread - "135i v Golf GTi"? More interesting was/is comparison between 125i and 125d ... And don't mention my mate's Dad's chipped 335d again, Shirley!

so you're comparing a mapped diesel vs standard petrol? have you got the torque curve for the standard 123d? oh wait, peak torque stops at 2000 or 2250rpm iirc?

i bet you could map the 125i to make peak torque higher if you liked.
