It's the same in power terms, the entry level 911 offering 350hp against the R8 V8's 430hp and the 4 S's 400hp falling way short of the 'basic' V10's 525hp.
Fundamental similarities remain though. Both are junior supercars with respectable prestige badges that won't scare the neighbours in the way something saucier like an Aston Martin, Ferrari, Lambo or McLaren might. An affirmative nod rather than a raised eyebrow and the whiff of trying too hard, if you will. Both are built from aluminium and are four-wheel drive, all-weather capable, happy to be used every day for 'normal' driving and both, now, can be had with seven-speed dual-clutch gearboxes that pretty much tick all the boxes of ease of use, residual protection and a nod towards real world fuel consumption and CO2. Crucially both are now acceptable choices in two-pedal form for the more purist end of their respective markets too. Quietly both have become, for the sake of a few options, six-figure purchases too.
And in the middle of the ranges - Carrera 4 S and R8 V8 - the overlap is pretty close. Price, performance, weight - all are to within a smidge of each other meaning anyone with £90K-plus to spend and the desire to own a prestige, four-wheel drive German sports car should be bending the ear of both Audi and Porsche sales execs.
