As the car industry progressively reduces CO2 and NOx emissions of their petrol and diesel engines required by European legislation, so the UK Government progressively raises the VED road and Benefit-in-Kind taxes even for the lowest emission and even hybrid models.
As an example in the recent Budget even the very lowest CO2 models emitting up to 50g/m of CO2 are currently rated at 5% for BIK tax, next year that goes up to 7%, then a year later 9%, then 13% and in 2019/20 16% and VED road tax are not exempt to increases either.
Fortunately, manufacturers are busy introducing lower emission Euro6 CO2 engines to their range and Audi for has introduced Ultra versions of their 2.0-litre TDI turbo-diesel engines for, A4, A5, A6 and A7 diesel models with more to come.
Ultra in my dictionary means ‘beyond’ or ‘extreme’ so my latest test drive in the mid-life refreshed Audi A6 Avant estate 2.0-litre TDI Ultra S-line. The latest A6 Saloon also gains the Ultra engine for the new model year.
The new potent 2.0-litre turbo-diesel engine sees power increased from 175bhp to 187bhp (190PS). There is 20Nm more torque as well, up to 400Nm from 1,750rpm. Fuel economy for the Avant model in the Combined Cycle soars from 55.4mpg up to 62.8mpg with CO2 emissions falling to 118g/km from 135g/km with the optional 19-inch wheels.
Under the new VED and BIK tax levies introduced from April this means the Avant test car is £0 for the VED First Year tax rate and then £30 for Year Two onwards and 21% for BIK company car tax. With the old non-Ultra technology engine it would be £130 every year for VED and 25% BIK. While we are talking about costs, the Audi A6 Avant 2.0 TDI Ultra with the most popular S-Line specification and the S tronic auto gearbox is priced at £37,935 on-the-road but with the usual addition of must-have options the test car carried a hefty price tag of £43,775. This included £1,050 for the 19-inch alloy wheels, not an option I would take as the S-Line with its 18-inch wheels has a more than firm enough ride anyway.
We know the A6 Avant well as a large, roomy, premium quality executive estate with ample room for five passengers and 565-litres of luggage space which increases to a substantially 1,680-litres with the rear seats folded.
For the mid-life refresh there have been minor tweaks to the styling and specification which adds further to the Avant’s refinement. Like most other Audis the interior design and quality is a masterclass for competitor BMW and Mercedes models. It is neither bland nor garish – you know real quality when you see it.
Core to this road test is the new Ultra specification engine. Some VW Group TDI turbodiesel engines can sound a bit rattley depending on which of the four main brands they are used in. With the Audi A6 Avant the four cylinder unit is very muted. It is well insulated with a cover over the unit to reduce noise outside and sound deadening materials behind the engine bay isolate noise from inside the cabin.
Even under load it doesn’t sound coarse and there was virtually no vibrations transmitted though the pedals or steering wheel.
The increase in mid-range torque is most noticeable and even in an estate car nearly five-metres long and with a gross vehicle weight of 2,355kg the performance is not dulled and the fuel economy is still good.
For the short journey drivers the good news is that the engine has a stop-start system which promptly activates with the new silky smooth gear changing auto transmission.
There are CO2 and NOx catalytic converters and a maintenance free diesel particulate filter fitted within the exhaust system so again continuous short trip motoring shouldn’t be a clogging issue for the system.
With the S-Line specification the A6 Avant has sportier exterior styling, a slightly firmer ride and with the optional 19-inch wheels it was firmer still.
But the handling and road holding was surprisingly good for such a large front wheel drive car and only impacts from the worst of the potholes resonated into the cabin.
The steering is well-weighted and can be adjusted along with throttle response and ride by using the Audi DriveSelect function. It is easy to adjust the latest A6 Avant and Saloon to focus more on economy, comfort or performance. In its 2.0-litre turbo-diesel sector it is now the clear class leader and lives up to its new Ultra classification and beyond the reach of many rivals.
