Expert review

The 2020 BMW 3 Series is a very well-rounded premium sedan, especially in M340i guise.

Does BMW still use “The Ultimate Driving Machine” as its advertising tagline? Yes, it does. And with the arrival of the 2020 BMW M340i, which slots between the existing 330i and the forthcoming BMW M3, the company proves there is substance behind the slogan.

Look & feel

8/10

As a younger man, I worked as a deckhand on a whale-watching boat out of Provincetown, Massachusetts. That summer on the Atlantic introduced me to all manner of marine life, and on several occasions, I got up close and personal with the majestic humpbacks that sidled up to the boat as though they were on a people-watching tour.

Something about the styling of the 2020 BMW 3 Series four-door sedan reminds me of those awe-inspiring creatures. Collectively, the lidded headlights, bulging curved hood, wide lower air intakes, and oversize grille give the car an aquatic appearance. And that pretty much wraps up my criticism of the 2020 BMW 3 Series.

Any remaining faults are forgivable because the 3 Series—particularly the new M340i trim—is just so damn glorious to drive.

Pricing is high, starting at $49,350 Canadian including destination charges for a base 330i—in Canada this includes BMW’s xDrive all-wheel-drive system but not even so much as extra-cost metallic paint otherwise—and rising to $62,100 for the M340i. My test car was the latter and had more than $11,000 in additional options (Canadian, estimated), bringing the total MSRP plus fees to a cool $73,250 (Canadian, estimated).

Having driven a 2019 BMW 330i with the M Sport Package, I’d say most driving enthusiasts would be quite happy with it while saving themselves a few grand. But if you can afford the added freight, good God the M340i is worth it.

Either way, BMW offers a variety of interior colours and materials to help personalize a 3 Series to your preferences. My test car’s off-white Ivory leather contrasted sharply with the otherwise black cabin and the Tanzanite Blue exterior paint, a $1,450 upgrade.

As purposeful in appearance as always, the interior also looks and feels like BMW is taking quality more seriously, which helps take the sting out of its sticker prices.

Performance

10/10

Some people say the previous-generation BMW 3 Series sedan wasn’t up to snuff in the driving dynamics department. That’s only partially accurate.

True, when BMW redesigned the car for the 2012 model year, swapping out the former version’s nearly telepathic hydraulic steering for electrically assisted hardware, the change left something to be desired.

However, BMW resolved that for 2016, redesigning the electric steering and making other modifications designed to make it feel more like BMWs of yore. When I sampled a 340i equipped with the changes, I was back in love with the 3 Series.

And the latest version is even better.

Significant structural and suspension changes, from greater component rigidity and reduced unsprung mass to new lift-related dampers and available M Adaptive underpinnings, contribute to the car’s definitive return to the sporty handling podium. The M340i’s upgrade from speed-sensing power assist steering to variable sport steering also amplifies the car's effortlessly tossable nature.

Combined with the robust 3.0-litre turbo inline six-cylinder engine making 382 horsepower and 369 pound-feet of torque, BMW’s rear-biased xDrive AWD drivetrain, a rear M Sport differential, and massive M Sport brakes clamped by signature blue calipers, the M340i trim’s engineering package puts a big sloppy grin on any driving enthusiast’s face.

Well, almost any driving enthusiast’s face. There is an elephant in the M340i’s cabin: the standard 8-speed automatic transmission.

So much for saving the manuals, eh?

As a driving enthusiast who has continually owned a manual transmission car since 1986, I accept this. Say what, now?

First, a launch-controlled M340i xDrive's powertrain rockets it to 100 km/h in 4.3 seconds, according to BMW. Second, in large cities, traffic is a nightmare. Third, when you’re really hustling in this car, the last thing you need to break your concentration is a botched downshift or missed upshift.

Maybe on a racetrack, I’d feel differently. But in the real world—even on a road you know as intimately as the wrinkles on your face—if you’re coming anywhere close to this car’s limits, you’ll be so focused on the task at hand that the delightful paddle shifters and the expertly calibrated eight-speed automatic transmission will prove a gift.

Of course, I missed shifting my own gears, especially since BMWs have silky-smooth gearboxes. But in a daily-driven car that encourages taking the long way home from work, the 3 Series M340i’s excellent sport transmission and various driving modes should be enough to ease this potential affront to BMW’s most loyal customers.

Form & function

7/10

Simple and supportive, the front seats in the 3 Series easily hold you in place while you explore the car’s handling capabilities. At the same time, they prove both accommodating and comfortable for longer periods of time. That’s important, given that the car begs to be driven even when you’ve got nowhere in particular to go.

Equipped with high-quality leather, front-seat heaters, and a heated steering wheel, our M340i xDrive test car was ready for winter. However, I tested it during an end-of-summer heatwave, and I wished BMW offered a ventilated seat option.

Rear-seat entry and exit proved awkward for me, but once inside, the 3 Series proved exceptionally comfortable. BMW positions the seat cushion and seatback in a way that provides terrific support, and substantial side bolsters snug you in closer to the centre of the car. My middle-aged abdominals, however, made a mockery of me as I tried to exit with anything approaching grace.

As is BMW tradition, some controls are hard to find or cryptic in terms of function. The climate controls are somewhat clumsily integrated with the vents, there is a proper stereo volume knob but a button for station tuning, and the digital instrumentation looks more like a video game than a proper BMW’s classic round gauges.

At the same time, however, the widescreen infotainment system screen is deftly integrated into the dashboard design, the latest 3 Series has the best version of iDrive in history, and BMW equips the car with one of the best natural voice recognition systems I’ve ever used.

Storage space is remarkably generous for a BMW, and today’s car buyers will definitely appreciate the covered bin forward of the shifter that contains an optional wireless smartphone charger. Officially, trunk space measures 479 litres, and while the trunk is deep, it is also narrow. Put a full-size suitcase into it, and it’s hard to see how the M340i holds more cargo than a typical family sedan. It certainly looks like it carries less.

Technology

9/10

Once upon a time—when it debuted nearly 20 years ago—BMW’s iDrive infotainment system was regarded as technology run amok.

Today, the latest version has little in common with the original. It features a touchscreen display, natural voice recognition, and gesture control in addition to the now-familiar knob and buttons on the centre console. With four main ways to interact with the system, it’s easy to pick a favourite or mix-and-match for more intuitive operation.

Topographically, the controls on the centre console aren’t as clearly defined as they were before, sitting on a nearly flat pad that looks clean and minimalistic but makes it harder to use them by touch.

Working similarly to a smartphone display, the touchscreen is terrific. Menu pathways are instinctive, and BMW has done a good job making a complex vehicle seem simple and easy to understand.

Gesture control is optional. Somewhat gimmicky, it turns a twirl of your finger into volume adjustment, and a hook or your thumb will change the radio station.

The “Hey, BMW” voice recognition system is excellent. It works similarly to a smartphone or home speaker assistant, responding to natural commands related to navigation, climate control, the stereo, and more. It can even find local, non-chain restaurants.

My test car also had the latest BMW head-up display, which is miraculously visible while you’re wearing polarized sunglasses. It’s faint, but you can see it. Baby steps, BMW, baby steps.

Safety

9/10

To equip a BMW 3 Series sports sedan with all the company’s latest and greatest advanced driving assistance systems (ADAS), you need to option the car with the Advanced Driver Assistance package.

Frankly, I think you can save yourself some money by skipping it. In my experience, while the safety features proved accurate during the few times I used them, smoothness was sometimes hard to come by. Besides, this car is so much fun to drive, I can’t imagine why anyone would want to turn everything over to cameras, sensors, and lines of code.

I will, however, admit that the rather rude and abrupt lane-keeping assist system is appropriate. It’s almost as though BMW is admonishing you to pay closer attention, reminding you that you’re behind the wheel of an ultimate driving machine, and you’re expected to be an active participant in the proceedings.

Should the ADAS fail to prevent a collision, rest assured that the BMW 3 Series is ready to take one for the team. The Insurance Institute for Highway Safety (IIHS) gives the 3 Series a Top Safety Pick+ rating when the car is equipped with the adaptive full LED headlights.

Cost-effectiveness

6/10

Though it includes free scheduled maintenance and warranty for the first four years or 80,000 km of ownership, a new BMW is rarely a cost-effective choice in a car. Starting prices are high, everything you really want costs extra, and before you know it, you’re blowing more than 70 grand on a 3 Series.

But, just like Disneyland, a BMW M340i delivers an immersive and legendary experience you simply can’t find anywhere else. And for that, you must pay.

True driving enthusiasts will find real value in the M340i. And for this performance-tuned version of the latest 3 Series, that might be all that matters.

It’s Just Right! Luxury, comfort, sport, while delivering good value.

April 10, 2025

Purchased the 2020 M340 , so far so good . I actually had an S4 previously. They are really similar but M340 takes the performance to the next level .

October 2, 2023

I have test driven only the M 340. It is excellent. I am currently driving an M240 convertible and if I was not a lover of the open sky would definitely trade this in. The power delivery is excellent and the interior is well appointed. I love the tactile feel. The steering wheel is a nice touch. The only criticism is that getting into the back can be a bit of a chore if you are over 6 feet.
