Audi announces 2015 A3 pricing

The last A3 we drove, an Irish-spec model with cloth seats and a 1.4 TSI engine paired with Audi's S-tronic twin-clutch gearbox, retailed for $54,495.

The Black Pack option on the Jaguar XKR is proving popular - nearly half of buyers are currently ordering it and the Speed pack - so Jag's rolling it out to the XF range as well.

The XF Black Pack brings dark grey 20-inch alloys, diamond-turned rims, gloss black grille and window surrounds. The purely cosmetic Black Pack kit will set you back £950 and is available on the XF diesel, 5.0-litre naturally aspirated petrol V8 and XFR models.
