Latest version of new Audi premium subcompact delivers highest output to date thanks to combined turbocharging and supercharging.
Turbocharging and supercharging share top billing in the new Audi A1 1.4 TFSI S line 185PS, which is available to order in the UK from this week priced from £20,705 OTR. The new top-performing A1 derives its performance from a combination of the two forced induction methods working sequentially 47.9mpg economy potential giving CO2 output of just 139g/km.
The compact and lightweight four-valve-per-cylinder ‘dual-charged' engine powers the A1 1.4 TFSI 185PS from rest to 62mph in 6.9 seconds, and on to a 141mph top speed. Under power, the supercharger is the first to exert its influence, intervening at around 1,500rpm to increase thrust.
As the supercharger takes care of low-range boost, it has been possible to use a larger turbocharger designed with optimum efficiency in mind, and this is reflected in the combined cycle fuel economy and low emissions.
