Which BMW 3 Series variant suits you?
BMW 3 Series cars have always appealed to buyers who appreciate the appeal of a business-class sedan that aims to satisfy driving enthusiasts. But which derivative of the G20-generation BMW 3 Series offers the best balance?
For decades, the BMW 3 Series has been the benchmark in the compact-luxury segment with its balance of performance, sporty handling, refinement, and prestige. Locally built for 35 years until 2018, the 3 Series has been the dream driver’s car for South Africans shopping in the business-class sedan class.
Most of the BMW (G20) 3 Series variants sold in South Africa are powered by 2.0-litre 4-cylinder turbopetrol and turbodiesel engines, with the single- and twin-turbo BMW inline-6 reserved for the range’s high-performance derivatives. Prices start at just over R900 000, going up to over R1 million for the top-of-the-range 330i (in October 2025).

BMW 320i, 320d kick off the 3 Series range
BMW’s 320i petrol is rated at 135 kW and 300 Nm, while the 320d turbodiesel model offers 140 kW and 400 Nm. As with all non-M BMW 3 Series cars, engine power is delivered to the rear wheels, and in the case of the 320i and 320d, that’s via an 8-speed automatic transmission.
The 320i badge was once associated with lethargic performance, but in the contemporary turbopetrol era, the BMW (G20) 320i offers more than sufficient performance to propel the Bavarian business-class sedan spiritedly, whereas the turbodiesel 320d, with its claimed average fuel consumption figure of 4.9 L/100 km, promises excellent efficiency for those who clock up many kilometres every year.
Like all 3 Series variants, a 5-year/100 000 km maintenance plan (which covers all motoring costs apart from car-loan repayments, insurance, fuel and tyres) is standard. Services are required when indicated.

Many choices for the driving enthusiast
Drivers seeking a more dynamic experience can choose the 330i M Sport. Though it no longer boasts a 3.0-litre inline-6 engine that its nomenclature historically denoted, it features a high-performance version of the (B48) 2.0-litre turbopetrol powertrain. The 330i M Sport pumps out 190 kW and 400 Nm of torque.

Also priced north of R1 million, the 330i M Sport is the last step before reaching the brawnier M340i xDrive, which, apart from having sportier exterior styling, is powered by a 3.0-litre inline-6 turbopetrol.

Watch Ciro De Siena’s video review of the 2023 BMW M340i xDrive:
The M340i xDrive delivers 285 kW/500 Nm to all 4 wheels, with the “xDrive” in the nameplate denoting an all-wheel drivetrain. At close to R1.4 million, it offers substantial value for the performance on tap!

M3 remains the class standard
For around R2.2 million, you can acquire the highly sought-after M3 performance flagship versions, available in station wagon format as the M3 Competition M xDrive and its sedan sibling, the M3 Competition M xDrive, for slightly less than the Touring.
Watch Ciro De Siena’s video review of the 2020 BMW M3 Competition M xDrive:
These M3s are powered by a 3.0-litre, inline-6 twin-turbopetrol engine engineered for liberal power delivery and immediate throttle response. With peak engine outputs of 390 kW and 650 Nm of torque, performance is staggering. BMW claims its M3s are good for 0-to-100 kph time of just 3.5 seconds.

Locally, the BMW 3 Series competes primarily against the following premium executive sedans:
- Audi A4: The traditional front-wheel drive alternative to the 3 Series, which was recently superseded by the A5 Sedan. Audi’s quattro all-wheel drive was only available on the M3-rivalling RS4 Avant, and the South African Audi A4 line-up didn’t feature any turbodiesel engines either.
- Mercedes-Benz C-Class: Often cited as the closest rival, the C-Class offers both petrol and diesel versions, as well as high-performance AMG variants. The AMG C63 S E Performance has a 2.0-litre 4-cylinder turbopetrol engine with hybrid assistance that produces 500 kW and 1 020 Nm, but the high-tech plug-in powertrain simply doesn’t have the evocative exhaust note of the M3’s inline-6.
- Lexus IS: Since the late 1990s, this has been Japan’s closest rear-wheel drive rival to the 3 Series. Less common than the 3 Series, it delivers an outstanding long-term ownership experience with the world-class build quality and durability that Lexus vehicles are renowned for. The 2-variant line-up relies on a 4-cylinder petrol-hybrid powertrain with less focus on performance than its rivals.
- Alfa Romeo Giulia: Offers distinct Italian styling, engaging dynamics, and competitive engines — including a 2.0-litre 4-cylinder- and a 3.0-litre 6-cylinder turbopetrol unit. The Giulia Quadrifoglio Super Sport provides M3-level performance and all-wheel drive. Like the Lexus IS, the Giulia’s not mainstream, but it serves as a strong alternative in the performance arena.
- Subaru WRX: For buyers prioritising a unique engine configuration, all-wheel drive grip and performance over prestige, design and cabin comfort, the WRX may be the value leader. The 2.4-litre flat-4 engine produces a solid 202 kW and 350 Nm, paired with the brand’s renowned all-wheel drive system. Subaru’s dealership network is very limited throughout South Africa, however.
BMW 3 Series summary
BMW created the compact executive sedan market with the 3 Series. It has always overinvested in the 3 Series engine and chassis development, creating compact sedans with excellent driving dynamics, especially the M3 range, which is one of the world’s great high-performance nameplates.
To many, the driver-centric cockpit ergonomics and overall dynamic balance of the G20-gen BMW 3 Series still make it the most desirable compact executive sedan. In the South African market, the 3 Series offers turbodiesel engines, which Audi’s A4/A5 doesn’t. And the M3’s powertrain has a lot more driver appeal than the AMG C63’s wildly powerful, but less characterful, 2.0-litre plug-in hybrid drivetrain.
