What is it?
A little bit of temptation for your company car list. The Audi A5 TDI Ultra sits alongside the A4 and A6 Ultras as the desirable two-door inclusion in Audi’s new range of fleet-targetted, low-emissions economy diesels.
It’s offered in front-drive form only, with one gearbox, one set of wheels and in one trim level – all of which is uncharacteristically straightforward for a German premium car maker. It also means you can’t inadvertently add £100 to your annual benefit-in-kind tax bill by ticking the wrong box on your order form – which is nice.
Mercifully, every A5 Ultra that Audi sells will be rated at 109g/km of CO2, and save a 40-per cent income tax paying fleet driver £370-a-year in BIK relative to an identically priced BMW 420d.
Replacing Audi’s range of ‘TDIe’-branded low-CO2 specials, the Audi A4, A5 and A6 Ultras use longer ratios for the higher intermediate gears than regular TDIs.
More crucially, their engines benefit from new high-pressure fuel injection and exhaust gas recirculation systems that make a peak 161bhp available over a wider band of revs than before, as well as making more torque – 295lb ft versus 280 – all from as low as 1750rpm.
Audi charges an identical list price for the A5 Ultra as a standard 2.0 TDI SE. Economy and emissions are improved from a combined cycle 61.4mpg in the regular 174bhp car to 67.3-, and from 120g/km to 109-. Meantime, the 0-62mph acceleration claim suffers to the tune of one solitary tenth of a second.
