With deliveries starting this November in the UK, the Audi A5 gets its first four-cylinder engine with a newly revised 1.8 liter turbo engine found in the Audi A3, A4, A6 and TT. This engine gets upgraded to Bosch's new DI-Motronic (direct injection) system which injects high pressurized petrol as a fine spray directly into the combustion chamber, whereas, the preceding 1.8T used a standard multi-port system which sprays fuel into the air intake system. As a result, power output and fuel efficiency improves.

The Audi A5 1.8 TFSI produces 170hp at 4,800-6,200rpm which is an increase of 7hp over its predecessor. Torque increases from 210Nm to 250Nm at 1,500-4,800rpm, fuel economy improves from 33.6mpg to 39.8mpg according to the combined cycle test and CO2 emissions drop from 202g/km to 169g/km. The A5 accelerates from 0-62mph in 8.4 seconds and has a top speed of 140mph.

The standard equipment found in the base V6 models gets handed down to the A5 1.8 TFSI essentially unchanged. One key option sure to be popular for the four cylinder model is the Xenon head lamps with LED daytime running lights which cost £775. The Audi A5 1.8 TFSI is available for order now with an OTR price of £26,190.

ALL-NEW TURBO FSI ENGINE FOR AUDI A5

Replacement for highly successful 1.8-litre Turbo engine brings yet more FSI efficiency to A5 coupe

New four-cylinder FSI engine for A5 combines turbo charging with direct petrol injection for excellent all-round performance
A5 1.8 TFSI available to order now with six-speed manual transmission for GBP 26,190 OTR or GBP 27,140 with Sport specification - first UK deliveries in late November
170PS @ 4,800-6,200rpm, 250Nm @1,500-4,800rpm, 0-62mph in 8.4 seconds, 140mph, 39.8mpg, CO2 169g/km

The first four-cylinder engine to power the all-new Audi A5 coupe joins the UK range this week, and fittingly it too is also a completely new design. The advanced, directly injected successor to the familiar 1.8-litre Turbo petrol unit that has powered A3, A4, A6 and TT models in the past creates the A5 1.8 TFSI, which is available to order now for an OTR price of £26,190. First UK deliveries are expected in late November.

Performance-enhancing turbo charging and fuel-rationing FSI direct petrol injection combine in the new unit to deliver 170PS at 4,800rpm and a healthy 250Nm torque peak that remains available from 1,500rpm through to 4,800rpm. As a result, the front-wheel-driven A5 1.8 TFSI with six-speed manual transmission passes the 62mph yardstick 8.4 seconds after take off, and can continue to a top speed of 140mph, all the while demonstrating a healthy dislike for petrol, with up to 39.8mpg possible according to the combined cycle test.

The extensive equipment list from which the first phase of V6-powered A5 models benefits is carried over largely unchanged to the four-cylinder version. It includes luxuries such as Milano leather-upholstery, advanced three-zone climate control and rear acoustic parking sensors, as well as sophisticated features like a space-liberating electromechanical parking brake which are more commonly to be found only in larger luxury cars.

Key optional features for this new lead-in model include Xenon head lamps with LED daytime running lights (£775), a Sport upgrade bringing larger 18-inch wheels, sports seats and further lowered sports suspension (£950), a 505-watt, 14-speaker Bang & Olufsen audio system (£525), the Audi Parking System Advanced with rear-mounted camera (£650) and Adaptive Light swivelling headlights (£325).
