Audi is adding the ‘ultra’ tag to its most fuel-efficient models; the Audi A6 ultra has already been launched, and now we have the Audi A4 Saloon, A4 Avant and A5 Coupe ultra.
The three new A4 and A5 TDI ultra models have CO2 outputs as low as 109g/km and are priced from £28,320.
Although it shares its 163PS output with the more powerful of the two TDIe engines, which until now was reserved for the A5 Coupé, the unit powering the latest ultra models is a completely new development engineered for even leaner burning with no impact on performance. It works with a highly efficient Selective Catalytic Reduction (SCR) system that removes nitrogen oxides from the exhaust and ensures that the new models meet the stringent new Euro 6 emission standards.
Acceleration from 0 to 62mph in the six-speed manual-equipped A5 TDI ultra is very slightly improved at 8.3 seconds (previously 8.4), with the same top speed of 140mph.
The new A4 2.0 TDI ultra can achieve up to 67.3mpg with CO2 emissions of 109g/km. The A4 Avant comes close, with 64.2mpg and CO2 output of 114g/km.
The A4 Saloon and A5 Coupe are now in VED band B (A5 Coupe TDIe previously band C), and in the A4 Avant is band C. Ultra technology also means competitive running costs for business users, with benefit-in-kind liabilities of 16 per cent, 17 per cent and 16 per cent for the A4, A4 Avant and A5 Coupe respectively.
Ultra specification will soon become available for more models in the Audi range, starting with the five-door A5 Sportback.
