The Audi A3 Sedan, which was announced in New York, has made its public debut in Shanghai, so we finally get to see it in the metal. The booted form of the third-gen A3, shaped as a four-door coupe rather than a classic three-box form, was on display at Auto China 2013 in 40 TFSI quattro model guise.

Audi’s numerical designations for its cars in China is quirky, with 35, 40 and 45 suffixes on them, for example. The A4 and Q5 40 versions for the market wear a 2.0 litre mill, so the 40 for the red show car means that it should be one too and the low-powered quattro form of the equation, the more powerful one being the S3 variant.

In Europe, three engines are available at point of introduction for the A3 Sedan, these being two petrol units, a 140 hp/250 Nm 1.4 TFSI with cylinder on demand and a 180 hp/250 Nm 1.8 litre TFSI, and a 150 hp/320 Nm 2.0 TDI oil burner.

Lots to like about the compact premium offering, which is 150 mm longer, 11 mm wider and nine millimetres lower than its Sportback sibling. It’s certainly a very clean-looking shape.
