BMW 3 Series

Powering the 330i is a 2.0-litre petrol that makes 258PS and 400Nm while the 320d features a 2.0-litre diesel that makes the same 190PS and 400Nm as before. Both models send power just to the rear wheels via an 8-speed automatic transmission.

The 3 Series will feaures just the 330i and the 320d. The 330i will be available in just the M Sport trim while the 320d will be available in Sport and Luxury Line trims.

The new 'G20' 3 Series is 76mm longer 16mm wider and sits on a 41mm longer wheelbase than before. It's also 55kgs lighter than the outgoing model and features a perfect 50:50 weight distribution. There's LED lighting all around and new headlamp and taillight designs in addition to subtle changes to the front and rear bumpers and the addition of the active kidney grill. All these changes contribute to a low 0.23 drag coefficient.

The new 3 Series now brings the entry level BMW sedan up to the level of it's current sedan line up - the 5 Series and 7 Series. So it also features similar 10.25-inch touch screen and a 12.3-inch TFT drivers info display. Gesture control has also made it's way to the 3 Series but it actually debuts BMW's new Virtual Assistance intelligent voice assistant that responds to 'Hey BMW' and controls entertainment, navigation and vehicle settings.

Mercedes Benz C-Class: Subtle changes to the interior and exterior of the new C-Class make a big difference to the overall package. It's more fun to drive now and while it's still not the enthusiast pleaser it's a better balance between comfort and fun and make the new C-Class a serios contender in the segment. Enthusiast's can now opt for the C 300d that makes an impressive 245PS and 500Nm.

Audi A4: The A4 was last updated in 2016 making it the oldest in this bunch. It's interiors are still quite impressive and though it isn't packed with as much tech as it's rivals it does features Audi's impressive Virtual Cockpit drivers information display. It's also a very relaxed and comfortable driving experience with great ride over bad roads. It's not going to appeal to any enthusiasts though with the lack lustre 1.4-litre petrol and 2.0-diesel engines the only available options.
