About Audi A4
The facelift model Audi A4 came in 2011. It features redesigned LED headlamps and taillights, front air dam with fog lamps, and closely set twin exhausts. Interior changes include Bluetooth connectivity for audio streaming (nav equipped models only) and a redesigned ignition key. Controls for air-conditioning, infotainment, and power windows gain chrome clasps. Other detail interior changes include larger steering column stalk switches first seen in the D4-series Audi A8 and a simplified layout for the HVAC control panel – for example the temperature setting for the heated seats is now directly set by a single button and is no longer controlled using the MMI dial. The A4 includes a radio with eight speakers as standard, while the MMI navigation system with voice dialogue is optional. A new “Drive Select System” allows drivers to choose comfort, dynamic, individual, or efficiency modes for fuel-efficiency. The power output of the 1.8 TFSI engine is 170 BHP and 320 Nm of torque – up 10 BHP and 70 Nm from the previous versions. Electromechanical power steering is standard.
In Europe, the wide range of Audi A4 saloon and Avant estate are available with the 1.8 TFSI, 2.0 TFSI gasoline engine, as well as 2.0 TDI, 2.0 TDIe, and 3.0 TDI diesel motor. Trim levels are Attraction, Ambition, and Ambiente. In the UK, the A4 range is offered in SE, SE Technik, Technik, S line, and Black Edition model grades. All-wheel-drive Quattro is offered in most engine and grade combinations.
For North America, the facelift model Audi A4 sedan is only offered with a 2.0 TFSI gasoline engine. Model grades are Premium, Premium Plus, and Prestige. The Avant was discontinued, leaving the Allroad Quattro as the only station wagon body style. For the 2016 model year, the A4 and S4 continued in B8 production. The B9 A4 would not reach the North American market until the 2017 model year, while the S4 variant would not be available until the 2018 model year.
The fifth-generation of the A4 was revealed in June 2015 when pre-production versions were released to the motoring press, with the official launch occurring at the Frankfurt Motor Show in September 2015. This generation of the A4 is the fifth to carry the A4 badge and is commonly referred to as the B9, representing the ninth generation of the Audi 80/A4 series, which were originally (but no longer) based on the B platform.
The B9 is slightly larger than the outgoing B8, but Audi claims the new A4 is around 120 kg (265 lb) lighter than its predecessor. For 2021, Audi’s Quattro all-wheel-drive powertrain is now standard equipment, as are lane departure warning and wireless Apple CarPlay. (Source Wiki)
