BMW 1 Series Review

If you want a premium family car that’s more enjoyable to drive than a Mercedes-Benz A-Class or Audi A3, the BMW 1 Series is a strong choice. There’s a wide variety of petrol and diesel engines - including a hot M135i model for those seeking sports car performance. 

There are some caveats. While its interior is better (and more practical) than ever, it still makes a fairly cramped family car. If you’re looking for something with a big boot, you’d be better putting your badge snobbery to one side and looking at a Skoda Octavia.

It’s also expensive compared to mainstream alternatives. Sure, a Kia Ceed or Ford Focus might not be on your radar, but a Volkswagen Golf is very nearly as good as the 1 Series and significantly cheaper.

Most BMW 1 Series models on the used market are powered by the 1.5-litre petrol engine, badged the 118i. That’s a good thing as we reckon it’s the best choice for the majority of buyers. It’s a characterful three-cylinder engine which combines peppy performance with wallet-friendly efficiency.

If you cover high miles, consider one of the diesels - a 1.5-litre badged as the 116d will appeal to the most frugal of buyers, while the 2.0-litre 118d is also a sensible option. There’s also a 120d which is available with BMW’s xDrive four-wheel-drive system, if that appeals.

Anyone seeking hot hatch performance should look for the M135i, which uses a twin-turbo four-cylinder 2.0-litre petrol engine - unfortunately, not the silky six-cylinder of the previous 1 Series.

Before parting with your cash for a 1 Series, you should also look at the Audi A3 and Mercedes-Benz A-Class. All three are competing for class honours - there’s little to differentiate between them, really. We reckon the A-Class’s interior perhaps pips the BMW’s for feel good factor and you get slightly more standard equipment on the A3, but there’s not a great deal in it objectively.

If getting more for your money appeals, you should also consider the Volkswagen Golf. It’s not got a premium badge but it’s certainly a step up from cars like the Ford Focus and Vauxhall Astra.

You won’t have any qualms with the quality of interior of the BMW 1 Series. It feels super premium, with soft-touch materials and shiny metal trims aplenty. All the knobs and buttons have a satisfying solid feel to them while even the indicator stalk feels like it’ll last forever. Insert a joke about BMW drivers here.

Sure, it might not have the instant wow factor of the Mercedes-Benz A-Class (there’s no ambient lighting here), but it actually feels more solid than the Audi A3. And that’s no mean feat.

We’ve mentioned the drab cloth seats of the entry-level SE model, but Sport models feature a number of extra features to make the cabin feel a smidgen more special. These include extra contrast stitching, Sensatec (fake leather) seats and the illuminated ‘Berlin’ interior trim. We’d recommend looking for a Sport model for these alone, otherwise you might as well be driving a Ford Focus.

Most 1 Series models come with BMW’s latest Live Cockpit Plus, which uses an 8.8-inch display which can be controlled via touchscreen or a rotary controller on the centre console. It’s a brilliant system - easy to navigate and fast to respond with sharp, bright graphics. The navigation works well, providing clear and logical directions and, well, performing exactly as you’d expect for a nav system in a premium car.

There’s also a larger 10.25-inch display (called the Live Cockpit Professional) which is standard on the M135i and offered as a desirable option on lesser models. This would have cost £1000 when new or would have been part of the £1500 Tech Pack 2, which also brought with it a fancy Harmon/Kardon sound system. Both of these features are worth looking out for on used models.

The bigger screen also brings with it BMW’s Intelligent Personal Assistant. This is a Siri or Alexa-like system - you activate it by saying ‘Hey BMW’, and it learns your preferences over time.

When the third-generation BMW 1 Series was first launched in 2019, BMW had the daft idea that it would charge owners an annual subscription fee for Apple CarPlay. Fortunately, after a lot of criticism (it’s free on a Kia Picanto…), it changed its mind. So, long story short, all BMW 1 Series models will have Apple CarPlay and you’ll be able to use it for free. Forever.

However there’s no Android Auto. Not even as an option. That’s one of our biggest gripes with the infotainment system in the 1 Series... and not just because we use an Android phone.

While the old BMW 1 Series was never a particularly practical choice, the latest model is significantly roomier inside - despite having much the same footprint as its predecessor.

That’s because the old car stuck with a rear-wheel-drive platform and longitudinal engines (hence the long bonnet) - great for wannabe Lewis Hamiltons - not so great for families doing their weekly shop. The new model is more conventional in its approach, and you’ll notice how spacious it is as soon as you take a seat.

There’s loads of head, leg and elbow room in the front of the 1 Series, along with plenty of stowage including large door bins and a usefully large cubby box under the central armrest.

Rear space is on a par with the Audi A3 and Mercedes-Benz A-Class, although that’s not saying much as none of these small premium cars feel particularly luxurious in the back. If you plan to regularly carry adults (or lanky teenagers) in the rear seats, you’d be better looking at a bigger BMW like the 3 Series or X3 SUV. Otherwise, anyone approaching six foot will touch the roof with their head and stick their knees into the front seats. It’ll be fine for short journeys when necessary, but it’s not comfortable for longer trips.

Of course, kids will be happier in the back, and there are Isofix child seat mounting points fitted to the outer rear seats. Access to these is pretty easy - especially as all 1 Series models now have five doors. You might want to consider a crossover SUV like the X1 or X3 as an alternative, though - your back will appreciate not having to lean over to fit child seats.

The boot is about as big as you’d expect from a car of this size, capable of carrying 380 litres of luggage with the rear seats in use (drop them for up to 1200 litres). 

That’s identical to the latest Audi A3 Sportback and Volkswagen Golf, and marginally bigger than the Mercedes-Benz A-Class’s 341-litre boot. Access is easy, with only a small lip, while an electric tailgate is available as a £500 option when ordering new. This is nice to have but wouldn’t be a deal-breaker, in our opinion - it’s not like the conventional boot lid is particularly difficult to open or close.

The most affordable engine in the BMW 1 Series is the 1.5-litre three-cylinder turbocharged petrol, badged the 118i. It’s the same engine that’s used in numerous BMW and MINI models, and it’s brilliant - punching well above its weight in terms of performance while also returning decent fuel economy.

This is available with either a six-speed manual or seven-speed dual-clutch automatic gearbox. We rate the auto - it changes gears quickly and makes day-to-day driving easier, but it will cost you more on the used market.

If you cover lots of miles, you’d be better with one of the multiple diesel offerings. With 116PS from its ultra-efficient 1.5 three-cylinder diesel, the 116d is intended to appeal to company car drivers more than anyone. You won’t see many on the used market and for good reason.

The big seller is the 118d, which uses a more conventional four-cylinder 2.0-litre diesel. With 150PS, this provides a considerable increase in performance over the 116d, and it’s no less efficient in the real world. Again, the 118d (and the 116d) is available with a choice of manual or automatic transmissions.

If you’re after a diesel with a bit of poke, the 120d provides 190PS and comes as standard with an automatic gearbox. Combined with xDrive, it can accelerate to 60mph in a fairly warm seven seconds.

Topping the range is the M135i hot hatch. This uses a 2.0-litre petrol engine producing 306PS, combined as standard with xDrive four-wheel-drive and an eight-speed automatic gearbox. This is a different beast to lesser 1 Series models, covering 0-62mph in 4.8 seconds - although it’s not quite as characterful as the old six-cylinder engine used in the previous hot 1 Series model. Let’s not get into the rear-wheel-drive thing again.

While the Audi A3 has the edge if you want an ultra-refined family hatchback, you’re unlikely to have any concerns with the refinement levels of the BMW 1 Series. There’s a little bit of wind noise thanks to its slightly blobby dimensions and you’ll notice road noise on the bigger alloy wheels, but it’s a more refined choice than mainstream alternatives like the Ford Focus.

There’s no perceptible vibration through the pedals, steering wheel or gear stick and all the engines are generally very muted. The 1.5-litre petrol used in the 118i is characterfully vocal when you build the revs, but it’s not as thrummy as a lot of turbocharged three-cylinder engines.

All of the diesels have a bit of a rumble on start-up, but that’s true for competitors too. They all settle down to a hushed idle when warm, with the stop-start system turning the engine off when you come to a halt at traffic lights.

As a relatively recent model, the 1 Series has all of the latest safety systems designed to prevent a crash or keep you safe in a worst-case scenario.

A collision and pedestrian warning system is standard across the range, including a city braking function which can automatically apply the brakes if it detects an impending collision at low speeds. It can also alert the driver to the presence of cyclists.

The lane departure system will alert you through an impulse in the steering wheel if it detects you straying from your lane.

At £1000, the Driving Assistant feature is quite an expensive option on new models, but worth hunting out if you cover a lot of motorway miles. This adds a blind spot detection system to the blind spot warning - it can even nudge your steering if you start changing lanes when a car’s in your blindspot. Other highlights of this pack include a rear crossing-traffic warning which will alert you to approaching vehicles when you’re reversing out of a parking space.

Euro NCAP crash tested the BMW 1 Series in 2019, giving it a maximum five out of five safety rating. It scored well across the board - achieving an 83% score for adult occupants, 87% for children, 76% for vulnerable road users and 72% for its safety assist systems. In reality, we’d expect no less for a modern car in this category, but the 1 Series is a very safe car to travel in.

The cheapest 1 Series to insure is the 116d, which falls into insurance group 16. There are no big surprises in the rest of the range - although it’s worth noting that the 120d ranks a number of insurance groups higher than the 118d. Of course, the costliest BMW 1 Series to insure is the BMW M135i.

These groups are all broadly in-line with competitor models like the Audi A3 and Mercedes-Benz A-Class. Of course, you’ll probably pay a little bit more to insure a BMW 1 Series than something like a Vauxhall Astra, but it shouldn’t cost a fortune unless you’re a young driver.

The third-generation BMW 1 Series is taxed under the latest VED bands. That means, from the second payment onwards, you’ll pay a flat £150 a year. The first owner will have covered the first CO2-based payment.

It’s worth watching out for the so-called premium car tax, which applies to any cars with a list price of more than £40,000. It’s difficult to spend this much on a 1 Series but it is possible - particularly if you find an M135i that’s loaded with options. As desirable as this is, it’ll cost an extra £325 a year in tax for its first five years. Even as the second owner, you’ll be responsible for this.

The entry-level 1 Series wears an SE badge, with standard kit including 16-inch alloy wheels, automatic air con, Bluetooth, the 8.8-inch Live Cockpit Plus infotainment system, cruise control, LED headlights, front and rear park distance control, rain sensor with automatic headlights and a sport three-spoke leather-covered steering wheel.

Most buyers will want to hunt out the Sport model for its 17-inch wheels, two-zone air conditioning, various nice interior touches (such as contrast stitching the instrument panel and door sill finishers), front sport seats and sport exterior highlights.

The popular M Sport model adds 18-inch alloy wheels, automatic headlights, Dakota leather seats, M aerodynamic body styling, firmer M Sport suspension and heated front sport seats.

The range-topping M13i xDrive builds on M Sport models with bespoke 18-inch alloy wheels, the bigger 10.25-inch Live Cockpit Professional Infotainment system and various M aerodynamic bodystyling upgrades.
