I have just been sent the new A3 Saloon brochure by my dealer. It seems at the moment Audi UK are only offering it in Sport or S-line. As far as I can see from a quick look most of the options available on the 3-door and Sportback are available and at the same prices. The basic prices are:
1.4 TFSI 140PS 7-speed S tronic £24,305.00
1.8 TFSI 180PS 7-speed S tronic £25,955.00
2.0 TDI 150PS 6-speed manual £24,275.00
1.4 TFSI 140PS 7-speed S tronic £26,455.00
1.8 TFSI 180PS 7-speed S tronic £28,105.00
2.0 TDI 150PS 6-speed manual £26,425.00
Personally I will be more interested when they release the 2.0 TDI 150PS with s-tronic.
