BMW resists the urge to build a rival to the Mercedes-AMG A45 S and Audi RS3, so its 1 Series flagship – the M135 xDrive – rivals those models’ A35 and S3 siblings instead. David Taylor gets behind the Bimmer’s wheel to see how it stacks up against its rivals.
As is customary, David is joined by videographer Shaun Korsten for this review, of which the focus is firmly on the performance metrics of the BMW M135 xDrive and how the F70-series flagship measures up against established contenders like the Volkswagen Golf R, Audi S3, and Mercedes-AMG A35.

BMW M135 xDrive: Design Evolution & Engine Specs
Although BMW is calling its F70-generation 1 Series an all-new model, David notes that the design of the premium hatchback (especially the front end) looks more like an evolution of the preceding F40 model.
Nevertheless, the BMW M135 xDrive makes a strong visual statement with its narrow daytime running lights, subtle M badge on the grille, and sporty wheels housing blue brake callipers.
Under the bonnet, the range-topper retains a 2.0-litre 4-cylinder turbopetrol engine, although its outputs reveal interesting changes. While power is up to 233 kW, torque has dropped by 50 Nm to 400 Nm.
David explores potential reasons for this torque reduction, speculating that it could be due to tighter emissions regulations or an effort to ensure the durability of the new transmission; BMW has replaced the previous M135i’s 8-speed torque-converter auto box with a 7-speed dual-clutch transmission.
Dual-clutch units are renowned for their faster shift speeds, and David confirms the M135 xDrive’s ‘box is quick, delivering the crisp, “rifle-bolt shifts” that traditional automatics struggle to replicate.

Real-World Performance Testing
To test BMW SA’s claim that the BMW M135 xDrive will accelerate from zero to 100 kph in 4.9 seconds, David takes the BMW M135 xDrive onto an empty stretch of road to perform a launch-control sequence.
After dialling the car into Sport mode and activating launch control, the results are remarkably consistent.
Our test gear shows the M135 xDrive repeatedly completes the sprint in 4.91 seconds, which validates BMW’s claim and showcases the all-wheel-drive system’s ability to put the power down consistently.
Aural experience & Driver Engagement
BMW has equipped the M135 xDrive with “BMW Iconic Sounds” (developed in conjunction with Hans Zimmer), synthesised engine noises played through the car’s speakers to enhance the driving theatre.
While David enjoys the “theatrics” of the pops and bangs, he acknowledges the ethical debate about manufactured sound in performance cars. He points out that switching this feature off results in a “deathly quiet” cabin, highlighting its importance for the fun factor.
The BMW M135 xDrive also features an array of drive modes beyond the standard Personal, Sport, and Efficient settings. Modes like “Expressive” and the rather unusual “Digital Art” are also included, which David finds slightly confusing for a focused performance machine.

BMW M135 xDrive: Driving Dynamics & In-car tech
Meanwhile, the BMW M135 xDrive utilises an all-wheel-drive platform with a slight front-wheel-drive bias, which provides incredible grip through corners. BMW has reportedly enhanced the handling by tweaking the dampers for a sportier ride, increasing chassis rigidity, and improving steering feedback.
David finds the BMW’s steering direct, though perhaps not as precise as those of its segment rivals.
He praises the grip and predictability of the chassis, noting that the all-wheel-drive system would be particularly effective in wet conditions.
The car includes a nifty Boost feature on the wheel-mounted shift paddle. Holding this paddle provides a 10-second countdown of full power, which David calls a “really cool party trick for overtaking.”
The cabin also features useful sport graphics that provide real-time data on power output, torque, and turbo pressure.

Does BMW M135 xDrive deliver a premium cabin ambience?
Once the high-speed thrills are over, the BMW M135 xDrive must also function as a premium daily driver. David confirms that the car manages to deliver a premium, well-appointed, and pleasant experience. It features a Harman Kardon audio system and sporty seats.
However, the cabin is a fully digital experience, meaning the climate controls have been integrated into the infotainment screen.
David misses the physical control of the iconic BMW iDrive rotary controller and points out that some of the materials used in the cabin may not be up to the standard expected of a vehicle at this price point.

Summary
David’s time with the BMW M135 xDrive confirms 2 things: it’s incredibly quick and the switch to the 7-speed DCT has undeniably sharpened its performance feel. However, the reduction in torque and the reliance on synthesised sound raise questions about how much visceral engagement it truly offers.
Is this all-wheel-drive machine, with its impressive grip and technology, a more satisfying driver’s car than its fierce rivals – the Volkswagen Golf R, Audi S3, and Mercedes-AMG A35? Although that is up for debate, David also notes a compelling argument for the M135’s pricing relative to the competition.
