The range of exclusive Audi ultra models is expanding with the addition of the A4 Saloon and Avant as well as the A5 Coupe. These cars offer significant CO2 output by delivering only 109g/km.

Two TDI engines are powering the vehicles. They both share a power output of 163 hp (120 kW) and works with a highly efficient Selective Catalytic Reduction (SCR) system that removes nitrogen oxides from the exhaust.

The peak torque here is rated at 400Nm (295 lb-ft), while the acceleration from rest to 100 km/h for the six-speed manual-equipped A5 TDI ultra is 8.3 seconds. The Vmax stands at 140mph. The same performance data also applies to the new A4 2.0 TDI ultra. However, the A4 Avant is covers the acceleration sprint for only 8.6 seconds, and has a top speed of 134mph.

Furthermore, the A5 ultra Coupe models are exclusively offered in the SE form, while the A4 and A4 Avant versions can be upgraded to SE specification. The latter adds to the standard equipment the following: 17-inch alloy wheels, an Audi Concert CD audio system incorporating DAB digital radio and linked to a 6.5-inch colour monitor, light and rain sensors, rear parking sensors and electronic climate control.

Inside, the A5 SE and A4 SE also feature Milano leather upholstery, while the A4 models also get additional features such as hard disk-based MMI Navigation plus, Audi Music Interface (AMI) iPod connection and the Audi Parking System Plus with front and rear sensors.

It is also important to mention that the cars are equipped as standard with lowered sports suspension, which reduces drag and maximizes fuel efficiency. Later this year, the ultra specification will become available also for the five-door A5 Sportback.
