2026 Subaru WRX Summary

The Subaru WRX – do we even need to introduce this iconic beastie at all? With its rally winning roots to being a legend in its own suburb, the ‘Rex’ is a sports car that’s affordable and fun – although the one we’re testing here is one of the pricier versions: the WRX tS Spec B.  

So what is a tS Spec B? Well, the old king of the WRX world – the STI – was retired at the end of the previous generation. Now this new grade – the tS Spec B – is the new WRX monarch. 

So does this mean the tS Spec B has more superpower than the rest of the line-up? Does it have a bigger engine? How much more does it cost? Does it have a manual gearbox? So many questions – the answers are 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.
