RAM-RAIDERS were once spoilt for choice in the fast-Audi lineup. Like an automotive footy shoulder charge, Mr Crim could simply turn aggressively towards a bank shopfront at speed and that stolen original-gen Audi S4 would reliably plough-understeer into it.
Taking the all-wheel drive system’s 60-to-75 per cent rear-bias, the optional mechanical differential can then send torque to an outside rear wheel to “nip understeer in the bud” according to the brand. It works, permitting the S5 Sportback to pivot on its axles while – in excellent ESC Sport – even allowing throttle-steer. No lairy oversteer, mind, but there’s sweet adjustability, sharp yet progressive steering and balanced (three-mode) damping.
This mostly applies to the $106K S5 Sportback as much as it does the S4 sedan and Avant, and S5 coupe and (soon) cabriolet. Audi buyers are these days the ones spoilt for choice.
It mirrors that sedan’s 480-litre boot but adds glass-up loading versatility, and while that volume is unchanged compared with the old model, there’s now 24mm extra rear legroom.
Headroom above the three-across back bench remains tighter than the sedan, though, and practically-speaking an S4 Avant offers the airiest rear surrounds and greatest (505L) luggage-swallowing – or, erm, ATM-carting – ability of all.
The Sportback is a halfway house, longer (+41mm) and taller (+18mm) than the coupe, with 59mm added to the now-Avant-equalling wheelbase, while being shorter (-12mm) and lower (-25mm) than that wagon.
The S5 Sportback can match the coupe and sedan’s 4.7-second 0-100km/h, and allied with a quick and adept eight-speed automatic, along with deep and silky acoustics, it feels realistic.
Inside, unique-to-S5 pillarless door frames greet the driver into a lovely leather sports seat, with full-colour driver and centre displays ahead and a long active safety list underneath.
Bodystyle overload it may be, but the S5 Sportback adds to a complete and alluring range that positions these Audis at the top of the circa-$100K sports-luxe medium class. And that is certainly a nicer place to be than wedged in a shopfront window.
