Audi launches fuel-efficient “ultra” versions of A4 & A5

The latest ultra models, which follow hard on the heels of the A6 version, offer CO2 outputs starting from 109g/km, undercutting the low emissions figures achieved by the familiar TDIe versions in each range.

The ultra models uses a new 161bhp engine with a highly efficient Selective Catalytic Reduction (SCR) system that removes nitrogen oxides from the exhaust and ensures that the new models are Euro 6-compliant.

Married to a six-speed manual, the engine offers maximum torque increased from 280lb.ft to 295lb.ft and available over a wider spread from 1,750rpm to 2,750rpm.

The result is a 0 to 62mph time of 8.3 seconds and top speed of 140mph for the A4 and A5 TDI ultra models along with economy and emissions figures of 56.5mpg on the official combined cycle test and CO2 emissions of 109g/km. The A4 Avant delivers a 0-62mph time of 8.6 seconds, a top speed of 134mph, with 55.4mpg official combined and a CO2 output of 114g/km.

As a result of their lower emissions, the A4 Saloon and A5 Coupe are in band B for Vehicle Excise Duty (A5 Coupe TDIe previously band C), while the A4 Avant is band C.

BiK liabilities are 16%, 17% and 16% for the A4, A4 Avant and A5 Coupe respectively. Comparing the new A5 Coupé 2.0 TDI ultra SE with the outgoing A5 Coupe 2.0 TDIe 163PS SE, the annual liability for a 40% tax payer falls from £2,236 to £1,988.

Like the A6 ultra, the new models are only differentiated from normal SE models with discreet “ultra” badging at the rear. A5 ultra Coupe models are available exclusively in SE form, while A4 and A4 Avant versions can also be upgraded to SE Technik specification.

All A4 and A5 ultra models are equipped as standard with lowered sports suspension to reduce drag and maximise economy, and for the same reason the 18-inch alloy wheels normally included as part of the SE Technik upgrade for A4 models are omitted.

The new ultra models are available to order now priced from £28,320 OTR and will reach their first UK customers in late April.

The brand added that it will continue its expansion of the ultra line-up, starting with the five-door A5 Sportback.
