title：2019 BMW 3 Series Review: 320d Road & M340i Track Test

content：Legacy Meets Innovation: The 7th Gen BMW 3 Series

For 40 years, the BMW 3 Series has defined the compact executive saloon segment—selling over 50 million units across six generations. The 2019 7th gen model is here, and Autocar’s hands-on test (covering the 320d road drive and M340i track performance) gives us deep insights into whether it lives up to its legacy. After analyzing the video, I believe this model balances luxury, tech, and driving fun better than most rivals.

Design & Platform: Bigger, Stiffer, and Divisive

The new 3 Series switches to BMW’s lightweight CLAR platform (used in larger saloons like the 5 Series). It’s longer, wider, and has a 25% stiffer body structure—key for handling and ride quality. Design reactions are mixed: some love its bold look, while others critique the oversized grille, fussy surfacing, or blingy wheels. It’s still a sharp saloon, but it lacks the timeless proportions of classics like the E30 or E46.

Engine Lineup: Efficiency and Performance

The 320d uses a new sequential turbo setup (small and large turbos) instead of the old twin-scroll system. It retains 187hp and 295lb-ft of torque but is more efficient and responsive. The engine sounds gruff at high revs—typical for a 4-cylinder diesel—but it revvs cleanly to 5,000 RPM.

For performance lovers, the M340i packs a 3.0L straight-six twin-turbo with 369hp and 369lb-ft—hitting 0-62mph in 4.4 seconds. Notably, it’s the first 6-cylinder petrol 3 Series with xDrive (four-wheel drive) since 1977.

Interior & Tech: Luxury and User-Friendly

The interior gets a major upgrade to compete with Mercedes C-Class and Audi A4. Highlights include digital instruments (elliptic gauges with a backward rev counter), iDrive7 infotainment (touchscreen + rotary controller), and natural language voice control (customizable name, e.g., “Charlie” or “Kit”). The cabin feels plush with aluminium trim, and rear space is adequate for adults.

Handling & Ride: Still a Driver’s Car

The 320d’s chassis features stiffer springs, anti-roll bars, and lift-related dampers (better comfort at mid-travel). The ride is firm but not harsh—trading a little smoothness for precise steering and rear-driven balance.

On track, the M340i shines: its xDrive system is rear-biased, allowing adjustable slides (with DSC off). It has no understeer, great body control, and strong brakes. Even with four-wheel drive, it feels like a classic 3 Series—engaging and fun.

The 2019 BMW 3 Series isn’t perfect—design is subjective, and the 320d’s engine lacks refinement. But it still delivers the driving joy that makes the 3 Series iconic, plus improved luxury and tech. It’s one of the best compact executive saloons on the market.

Toolbox for Prospective Buyers

Checklist:

1. Test drive the 320d for daily commute comfort.
2. Try the M340i on twisty roads or a track to feel its performance.
3. Test iDrive7’s voice control with natural commands (e.g., “Take me to the racetrack”).
4. Check rear seat space for passengers.
5. View the car in different lighting to assess its design.
