2020 BMW Z4 M40i Review: Sporty, Good Handling & Comfy
The 2020 BMW Z4 M40i Roadster tested on the road and on the track. The third generation of the BMW Z4 has been in dealerships for a few days.

Although the Z of the name stands for Zukunft, meaning “future” in German, the BMW Z4 M40 draws from the past some decidedly important characteristics.
For starters, the BMW has never abandoned its beautiful engine 6-cylinder, available in several versions and fractionation perfect and without vibration. And the “six in line”, 3 liters of direct petrol injection with BMW TwinPowerTurbo supercharging with 340 hp, is what we find under the long bonnet of the 2020 BMW Z4 M40i. A car that has returned to the classic canvas roof, instead of the heavy electric rigid roof of the middle generation, and which has a stylistic dynamism which goes hand in hand with performance.
Speaking of performance, the 0-100 km / h acceleration takes place in 4 ”5/10 while the maximum self-limited speed reaches the standard 250 km / h. Electrically lowered the hood in a few seconds, we immediately appreciated the unmistakable sound of the 6-cylinder BMW, not at all disturbed by the now essential boost. A way to guarantee both low emissions and high performance.
The 3-liter of the Z4 pushes hard right from the speed just beyond the minimum and shows further aggressiveness from 4,500 rpm up to over maximum power. All well supported by the 8-speed Steptronic automatic transmission with torque converter. What you end up using most often in the fully automatic mode is the timeliness and smoothness of the passages.
Okay, there is the manual function that can be implemented via the central lever or the paddles on the steering wheel. However, this setup requires automatic switching to the higher gear if you insist on the accelerator beyond the maximum power speed. And this is not the best. Because it prevents you for example from holding the second in a tight curve until the intervention of the limiter. Even the weight, albeit less than in the past, partly influences the perception of those looking for an extreme car.
Aspects like the rear-wheel drive, the 50:50 weight distribution on the two axles and the refined 5-link multilink rear axle predict a cornering behavior of 10 and praise. I am confident that by testing the BMW Z4 M40i it is confirmed because the entries in the curve take place “at the speed of thought”. Trajectory maintenance is also remarkable and attitude neutrality is both reassuring and fun. The 5-link multilink rear suspension helps a lot to encourage this behavior. Recovering much better camber than for example the McPherson of a Porsche Boxster and positively influencing the work of the front end with double-jointed arms.
The steering is the right one to face curves and counter-bends, driving as it should, without becoming anxious in long highway bends. Even the DSC does not penalize sports driving in the wet at all, as its interventions are rare and slight. Of course, we excluded him completely on the track. And at that point, we realized how the 2020 BMW Z4 M40i is a fantastic car, with a widely manageable power oversteer and an innate ability to self-realign. Here, in fact, electronics is complementary, because the attitude technique, “iron” as they say in jargon, is simply exemplary.
