It is four cylinders to six.

Although the BMW M135i looks the same, the two platforms underneath are quite different. BMW has changed the car’s foundations. It now uses a front-wheel-drive layout, but all-wheel drive is also available. The new 1 Series also saw a reduction in the number of cylinders, with the model moving from a six-cylinder turbocharged inline-si motor to a four-cylinder turbocharged unit. How do these changes affect the track? The Leaseloco YouTube channel has released a new video that pits them against each other to determine who is the best performer.

The 2020 M135ixDrive features a turbocharged, 2.0-liter four-cylinder engine with 306 horsepower (228 Kilowatts) as well as 332 pound-feet (405 Newton-meters). Compare this to the 2019 M140i with its 3.0-liter straight six engine, which produces 335 horsepower (250 kW) as well as 369 lbft (500 Nm), of torque. All-wheel drive is one advantage of the M135i. This gives the BMW M135i a slight advantage over the M140i, an older rear-wheel-drive model. The 2019 model is lighter than the 2020.

In the first race, the AWD M135i took an early lead. However, the M140i, which is more powerful, quickly closed the gap and pulled ahead. The M140i crossed the finish line in 13.6 seconds. The M135i was only a fraction behind with a time of 13.61 seconds. Next, a rolling race will be held at 50 mph (80 kph) starting. The M140i, which is older, pulls away. It’s too strong for the M135i. The last competition between them was a brake test at 70 mph (113 km/h) to zero. The lighter M140i won this with ease.

The M135i is the successor of the M140i but they do have some real differences. The automaker was able to make the best car for this segment with the changes to the 2020 BMW 1 Series, even though it meant changing the powertrain layout.
