2020 BMW 3 Series Reviews Summary

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.

2021 Mercedes-Benz E-Class Reviews Summary

When money is but a mild concern, a brand-new Mercedes-Benz is a reasonable purchase. The Mercedes-Benz E-Class is the company's most practical and versatile car, as high-quality and necessary in a nice garage as a Kitchen-Aid mixer is in a baker's kitchen. It offers four body styles, four engines, and dozens of colour schemes. Fast or efficient? Loud or library quiet? Modest or rich as hell? The E-Class, the brand's midsize car, is all of those things, depending on which of the 13 models you order and how deep into the options list you dive. For 2021, the E-Class receives a mid-cycle update for the infotainment system, engines, and exterior styling. We tested the Mercedes-AMG E53 that features a mild-hybrid inline-6 powertrain.

2020 BMW 3 Series

8/10

2021 Mercedes-Benz E-Class

9/10

The 2020 BMW 3 Series evoked a sense of aquatic elegance, reminiscent of majestic marine life. Its design featured lidded headlights, a curved hood, wide lower air intakes, and an oversized grille, creating an appearance that was both dynamic and graceful. Despite its high pricing, the 3 Series, especially the M340i trim, was celebrated for its exhilarating driving experience. The interior offered a variety of customization options, with high-quality materials and a focus on improved quality, making the premium price more palatable.

In contrast, the 2021 Mercedes-Benz E-Class embraced a design philosophy of "sensual purity," with fluid, curvier forms that were slightly edgier than its predecessors. The E-Class was available in various body styles, each exuding elegance and sophistication. The interior was a showcase of luxury, with rich materials, intricate details, and advanced technology. Despite the absence of the classic standing hood ornament, the E-Class maintained its reserved and conservative exterior, while the interior was a lavish and inviting space.

The 2020 BMW 3 Series was praised for its return to sporty handling, thanks to significant structural and suspension changes. The M340i trim featured a 3.0-litre turbo inline six-cylinder engine producing 382 horsepower and 369 pound-feet of torque. It was equipped with BMW’s rear-biased xDrive AWD drivetrain, a rear M Sport differential, and M Sport brakes. The 8-speed automatic transmission, while not manual, was expertly calibrated, offering a launch-controlled acceleration to 100 km/h in 4.3 seconds. The car's various driving modes and paddle shifters enhanced the driving experience, making it a joy for enthusiasts.

The 2021 Mercedes-Benz E-Class introduced electrified inline-six powertrains, with the E450 model featuring a hybrid system that provided extra power and torque. The E450's 3.0-litre engine produced 362 horsepower and 369 pound-feet of torque, with additional overboost from the battery. The AMG E53 model added a second turbo, delivering 429 horsepower and 384 pound-feet of torque. The AMG E63 S, with its 4.0-litre V8 engine, produced 603 horsepower and 627 pound-feet of torque.

8/10

The 2020 BMW 3 Series offered supportive front seats that were both comfortable and accommodating for long drives. The interior featured high-quality leather, front-seat heaters, and a heated steering wheel. Rear-seat entry and exit were somewhat awkward, but once inside, the seats provided excellent support. The infotainment system was well-integrated, with a widescreen display and the best version of iDrive to date. Storage space was generous, with a trunk capacity of 479 litres, although its narrow design limited its practicality.

The 2021 Mercedes-Benz E-Class boasted a spacious cabin with ample headroom and legroom for four adults. The interior featured redesigned infotainment controls and a user-friendly layout. The E-Class offered various body styles, each with different cargo capacities, such as the sedan's 540 litres and the wagon's 640 litres. The E-Class Coupe and Convertible provided comfortable rear seats, while the wagon included a stowable rear-facing jump seat. The E-Class All-Terrain model added versatility with increased ground clearance and body cladding.

The 2020 BMW 3 Series featured an advanced iDrive infotainment system with a touchscreen display, natural voice recognition, and gesture control. The system was intuitive, with multiple ways to interact, including a knob and buttons on the centre console.

The 2020 BMW 3 Series offered an Advanced Driver Assistance package with various safety features. While the systems were accurate, they sometimes lacked smoothness.

The 2021 Mercedes-Benz E-Class was one of the safest cars available, with a five-star overall rating from the NHTSA and a Top Safety Pick+ rating from the IIHS. The E-Class featured innovative safety technologies, such as Pre-Safe Sound and side collision protection. Standard safety features included forward automatic emergency braking, a driver-attention monitor, and blind-spot monitoring, with additional driver-assist features available as options.
