The range of Audi Ultra models which launched with the A6 last month is expanding to include A4 Saloon and Avant and A5 Coupe variants.
With CO2 outputs of as little as 109g/km the three new A4 and A5 TDI Ultra models undercut the low emissions figures achieved by the familiar TDIe versions in each range. They are available to order now priced from £28,320 OTR and will reach their first UK customers in late April.
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.
The outstanding emissions performance delivered by the three new models has a bearing on their CO2-related Vehicle Excise Duty categorisation, which in each case is band B (A5 Coupé 2.0 TDIe was previously band C).
The Ultra technology also facilitates exceptionally 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. If the A5 Coupé 2.0 TDI ultra SE is compared with the outgoing A5 Coupe 2.0 TDIe 163PS SE, the annual liability for a 40 per cent tax payer falls from £2,236 to £1,988.
