2023 BMW 3 Series Summary

Back in the day, the 3 Series sedan was often the entry to the brand for first time BMW owners, and for good reason. They offered practical interior space without compromising on engine performance.

And they simply looked good, no boring nanny design elements. Then the 1 Series came along and price points bumped up, so how does the ‘entry’ BMW 320i M Sport live up to its long-standing reputation?

With an updated dashboard that brings the interior and tech up to market and a sharper exterior design, it more than holds its own at the table of luxury sedans, despite hard competition from the likes of the Audi A4, Mercedes-Benz C200 and Jaguar XE.

However, if the Merc is a placid and well-behaved mare… the BMW is the barely-broken-in bronco and it takes a certain kind of ‘rider’ to enjoy what the 320i has to offer.

I’ve been discovering just that this week with my family of three. What did we find out? Read below!

2026 Mercedes-Benz CLA-Class Summary

Mercedes-Benz has shifted its CLA compact coupe-style sedan from support player to headline act with the introduction of this all-new, third-generation version.

It exemplifies the German giant’s multi-powertrain approach with an expansion of the local line-up from two pure-combustion variants to a five-model range comprising three hybrid and two pure-electric options.

CarsGuide was invited to sample the hybrid version of the newcomer (the EVs arrive in July), so stay with us to see if this sleek four-door is your kind of premium European compact sedan.

Verdict

I thoroughly enjoyed my time in the BMW 320i M Sport. It’s fun to drive and I felt connected to what the car was doing on the road. The harder ride may not appeal to some but I didn’t mind it. The cosy back seat and boot mean it will probably suit a smaller family best and one which doesn’t have to worry about carrying a lot of gear around regularly, but it suited my needs just fine.

I reckon this is a car for those drivers who don’t want to compromise on performance but still have a kid or two. If you’re after the cushioned comfort of a Merc, this won’t appeal but I didn't want to give this one back and happily give it a firm 8/10.

My son liked the sports car looks and enjoyed the amenities in his row. He gives it a 10/10.

Verdict

The broadening of the CLA’s scope in this third-gen version puts it a step ahead of key rivals and raises the compact sedan’s prominence in the three-pointed star’s local line-up. Its combination of quality design, performance and efficiency is compelling. And we’ll drive the battery-electric version as soon as it lands.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
