People may ask, which is better, M135i or M140i? Currently the quickest and most powerful 1 Series car available for purchase, the BMW M140i occupies the top spot in the small car hierarchy. The BMW M140i has the well-known 3.0L BMW B58 engine. With 335 horsepower, it isn’t nearly as powerful as the BMW M2, the 1M Coupe from the previous generation.

Although BMW renamed the vehicle from M135i to M140i in 2016, it was virtually the same car with additional power, stronger suspension, and increased efficiency

The M140i’s appeal lies in its ability to provide all the functionality of the base 1 Series along with the extra power of a 3.0-liter straight-six turbocharger. Rear-wheel drive is standard on all variants, which contributes to its excellent handling relative to other hatchbacks.
Sat-nav, DAB, Bluetooth, 18-inch alloy wheels, and an M Sport body kit are now standard on all versions. Although keyless entry, adjustable dampers, and a reversing camera are additional costs, leather sports seats, climate control, and rear parking sensors are standard features.

BMW M140i: Engine, Performance, and Drive

The M140i is an absolute pleasure to drive, and its superb engine is at the core of its allure. The six-cylinder’s nicely tuned exhaust tone and seamless operation extend to 7,000 rpm. It’s fast as well, reaching 62 mph in just 4.9 seconds, but what really stands out is the in-gear quickness. This is particularly impressive given the eight-speed automatic’s closely spaced ratios and 500 Nm of torque at just 1,300 rpm.

Although selecting the automatic increases the cost by about £1,500, it is almost as good as the A45 AMG with its double clutch, fast shifts, steering wheel-mounted paddles, and strong manual control. It also accelerates ever so slightly, cutting the manual’s 0-62 mph time by 0.2 seconds.
If you choose a manual, though, you won’t be sorry. It provides an ideal driving position for those seeking a lively ride. It has a hefty yet pleasurable shift action.

The M140i’s exquisitely balanced rear-wheel drive chassis is another major selling point. Plenty of grip and nimble handling go hand in hand with quick and accurate steering. While the Mercedes-AMG A45 has better body control, the BMW’s performance and handling don’t compromise comfort or refinement, thanks to a respectable ride.

BMW M140i: MPG and Running Cost

Good residuals and fixed-price servicing are major benefits in terms of running costs. Additionally, because the BMW is less expensive than the Mercedes, company car users will still pay comparable monthly taxes despite the greater emissions. The manual M140i is 30% BiK, while the auto is in the 28% BiK range. The BMW M140i can be categorized as a fast car.

The vehicle’s stated fuel efficiency is 39.8 mpg, but in mixed driving, don’t expect it to average much more than 26 mpg.

Interior, Design, and Technology

After receiving a facelift in 2015, the 1 Series received new exhausts, front and back lights, and bumper adjustments. The M135i was redesigned as the M140i in 2016.

The M140i’s modest body modification enhances the sporty design of the base car, giving it a wider stance on the road and flared wheel arches. The 3.0-liter straight-six’s exclusive grey alloy wheels may easily be confused for a less expensive standard 1 Series in M Sport trim at first glance.
But if you look closer, you can see the distinctive twin-exit exhausts, blue brake calipers, and gray mirrors of the M140i. The sporty BMW feels exceptional inside because of its well-designed cockpit, superb driving position, and premium materials. It also comes equipped with standard features like climate control, Bluetooth, sat-nav, and leather seats.

Cargo and Comfort

Though it prioritizes handling and performance, the M140i is as useful as any other 1 Series. Despite having a 30mm longer wheelbase than the first generation of BMW’s popular hatchback, the 1 Series is still somewhat smaller in the back than a VW Golf.

The 360-liter boot now holds 19 more liters than the Mercedes A-Class, despite the fact that the 1,200-liter foldable seat capacity is 43 liters less than the high-roofed Merc.

Nevertheless, the layout of the 1 Series boot is highly practical, and the cabin is well-stocked with compartments. Thanks to the addition of BMW’s Extended Storage option, which is now standard on all models.


The BMW 1 Series has received the maximum five-star Euro NCAP rating of 91 percent for adult occupant safety. Six airbags, seatbelt reminders, and electronic stability control are standard equipment on all models. However, lane departure warnings and a radar-assisted braking system, which slows the vehicle down to prevent collisions, are noteworthy additions to the extensive list of safety features.

Its maximum speed is also expected to be 155 mph. It’s interesting to note that the speedometer near the end of the movie shows a top speed of 160 mph, which is a little faster than the factory specs.
