The BMW 1 Series and Mercedes-Benz A-Class are two of the most popular premium hatchbacks on the market, offering buyers a blend of upscale features and compact practicality. Both cars have been updated within their current generations, with the latest 1 Series arriving in 2024 and the A-Class receiving a facelift in 2023. While they share a similar premium positioning, each model brings its own strengths to the table.
The 1 Series remains BMW's smallest and most affordable offering, aimed at giving buyers an accessible entry point into the brand's range. Meanwhile, the A-Class has evolved from its unconventional MPV-like origins into a sleek and stylish hatchback (and saloon) that delivers the full Mercedes experience in a compact package. Both models face stiff competition not just from each other, but also from rivals like the Audi A3 and Volkswagen Golf.
BMW 1 Series vs Mercedes-Benz A-Class
Practicality
Both the BMW 1 Series and Mercedes-Benz A-Class offer decent practicality for the premium hatchback segment, though neither is class-leading in this area. The 1 Series provides 380 litres of boot space, on par with the Audi A3, though mild hybrid models lose some of this capacity to battery storage. Access is a bit narrow, and there's a load lip, but the space itself is a useful square shape. Space in the back seats is very similar to what you'll find in the A-Class. If you need more room, try a Skoda Octavia instead.
The A-Class hatchback's 355-litre boot is a bit smaller than its rivals, though the saloon body style increases capacity to 405 litres. As with the BMW, there's adequate space for two adults in the back seats, but it's a squeeze for three, and headroom is slightly tighter in the saloon. Interior build quality is to the same high level across both cars, so it's really a matter of personal preference as to which suits your taste.
Driving Impressions
The BMW 1 Series prioritises driving enjoyment, with sharp handling and strong body control that delivers an agile, pointy feel. The steering is direct, while the M Sport suspension is firm but copes well with all but the worst surfaces. All-wheel-drive xDrive variants have a neutral, surefooted balance.
Engine choices currently comprise three turbocharged petrols - the punchy 120, potent 123 xDrive, and rapid M135 xDrive hot hatch. All use a smooth-shifting seven-speed dual-clutch auto. Even the base 120 has enough performance for most, while the M135 offers thrilling acceleration without being unruly.
The A-Class trades some of the BMW's dynamism for a more comfort-oriented approach. Handling is composed and the steering precise, but it's not quite as engaging as the 1 Series. However, it rides comfortably and makes an excellent motorway cruiser, especially with smaller wheels.
Engine options span frugal diesels and petrols, plus a plug-in hybrid (which you can't have on the BMW). Most buyers will find the A200 petrol's performance ample, though the entry A180 struggles. The hot AMG A35 and ballistic A45 S provide serious thrills for those wanting more power.
While the Mercedes offers a more relaxed demeanour, the BMW's superior driving dynamics and slightly broader performance range give it an edge for enthusiasts. But both cars strike an appealing balance for daily driving.
Technology and Equipment
Both the 1 Series and A-Class feature upscale, modern interiors with impressive levels of technology. However, there are some key differences in their approaches.
The BMW's iDrive infotainment system was once class-leading for usability, but the lack of a rotary controller in this latest generation of 1 Series is a backward step for ergonomics. Physical air-con controls have also been sacrificed. That said, the large screens look sharp, menus are logically arranged, and functionality like navigation and smartphone mirroring is all present.
Mercedes' tablet-style MBUX system in the A-Class is visually striking, with detailed graphics across its dual screens. While taking some familiarisation, it's very responsive, with great voice controls. Higher specs get augmented reality nav too. While the interface is beginning to feel dated next to newer Mercedes models, it stands up well against BMW's latest system.
Both cars come well-equipped from the base level, with the BMW including luxuries like heated seats and LED lights as standard. However, some key features like wireless charging or adaptive cruise require pricey option packs.
It's a close-run thing between these two strong contenders but the Mercedes shades it for our testers. Both impress, though, so which one you prefer might simply come down to which brand you like the most.
Running Costs
On purchase prices, the BMW 1 Series and Mercedes A-Class are very close model-for-model, though neither is inexpensive. The 1 Series range starts from around £31,000, while A-Class pricing kicks off just below £30,000. Opt for a hot hatch AMG A35 or M135 xDrive and costs rise substantially.
When it comes to fuel efficiency, the A-Class has the slight edge - especially if you choose a diesel, with even the range-topping A220d returning up to 55.4mpg in official tests. The A250e plug-in hybrid can achieve excellent economy with its electric range, provided you can plug it in on a regular basis. The BMW's mild hybrids score up to 53.2mpg for the 120 petrol, though the M135 is predictably thirstier.
Both brands offer fixed-price service plans to help budget for maintenance. And in both cars you'll need to watch out to see if the list price when new tips over £40,000, because in that instance you'll need to pay hundreds of pounds extra in luxury car tax each year.
Overall, there's little to split them on running costs if you stick with an internal combustion engine. However, anybody wanting plug-in hybrid power (which might well be you if you're a company car driver) will need to go with the Mercedes.
Verdict
The BMW 1 Series and Mercedes-Benz A-Class both make a compelling case in the premium hatchback class. The BMW prioritises driving engagement, with tidy, agile handling and a punchy range of engines led by the potent M135 xDrive. However, its updated interior has taken a step backwards for ergonomics and ease of use.
In contrast, the Mercedes trades the BMW's outright dynamism for a more relaxed driving experience and superior ride comfort. Its visually-striking MBUX system looks upmarket, while cabin quality is a real strength. It can't quite match the 1 Series for driving fun, but it's still a good steer.
With much to like on both sides, it might ultimately come down to which you prefer the look of, or what kind of a deal you can find. Or, let's be honest, which premium badge appeals most. Either way, you'll be getting a very desirable compact hatchback.
