LATEST AUDI A5 RANGES SET THE EFFICIENCY STANDARD
Subtle re-sculpting and significant re-engineering will enable new generation Audi A5 and S5 Sportback, Coupe and Cabriolet models to slip even more elegantly, more nimbly and more cleanly through the air. Beyond their measured exterior and interior styling updates, infotainment technology advances and chassis modifications, the three ranges are also characterised by CO2 emission reductions of up to 22 per cent thanks to new and heavily revised engines and additional efficiency measures.
The key objective in updating the three ranges was to deliver major gains in efficiency without compromising on performance that fulfils the promise in the taut and muscular lines of the A5. This has been achieved primarily by introducing two new engines and completely redesigning others, but also by extending engine start-stop technology right across the range and replacing the hydraulic power steering system with a new electromechanical unit that demands no engine input when the wheel is in the straight-ahead position.
In realigning the engine range, Audi has remained true to its philosophy of using forced induction to compensate for cubic capacity in the interest of economy. The existing naturally aspirated 3.2-litre V6 petrol engine has been replaced by a new 272PS version of the supercharged 3.0-litre V6 unit in A5 Coupe and Cabriolet variants. The existing 333PS version of this engine, which already powers the S5 Sportback and S5 Cabriolet, will also now replace the 4.2-litre, naturally aspirated V8 in the S5 Coupe.
Equipped with its new and 20 per cent more efficient engine, and with standard S tronic twin clutch transmission in common with its Sportback and Cabriolet counterparts, the S5 Coupe can power to 62mph from rest in 4.9 seconds – a 0.2-second improvement over its V8-powered predecessor – on the way to a governed 155mph top speed. Combined fuel economy stands at 34.9mpg, a significant improvement over the tiptronic V8 Coupe’s 26.4mpg.
