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.

2021 Mercedes-Benz S-Class Summary

It's only in the running for the title of world's best luxury car. No biggie here, then.

Like Rolex and Concorde, S-Class has become a byword for ultimate, and deserved or not, the Mercedes-Benz defines its segment despite the best efforts of the BMW 7 Series, Audi A8, Lexus LS and (sadly now-defunct) Jaguar XJ, as well as pointing the way forward with new technologies that eventually trickle down to more proletarian models.

Replacing the half-million selling W222 unveiled in 2013, the W223 is the latest in a long line since the first W187 Ponton debuted in 1951, and includes the famous ‘Finnies' and Stroke-8 models that followed immediately afterwards, but it is the 1972 W116 that really set the template.

Now, seven generations in, the 2021 S-Class is all-new again, with progressive safety and interior features that should help keep it Australia's bestselling full-sized upper-luxury sedan.
