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.

2018 Mercedes-Benz E400 Summary

It is hard to immediately think of a country more suited to the convertible life than Australia. Even our coldest states (you know who you are…) are blessed with more warming sun than almost anywhere else on the civilised parts of the planet, so you’d think we’d be swanning about in dropped-top bliss almost year round.

But it’s actually in the UK (despite being cold, grey and almost always underwater) that convertibles really fly out of dealerships, with sun-starved Brits buying more than anyone else in the world. Weird, right?

Still, here they remain something of an oddity, sold in small numbers to drop-top diehards. At least partly because the convertibles of old were almost always slightly worse than their hardtop equivalents. 

But Mercedes - which makes more convertibles than most - claims to have mastered the soft-top formula with the E400 4Matic, a car it says offers all the perks of open-air motoring without any of the dynamic or practical downsides.
