The new A4 practically shares its handsome lines with the current model, but Audi has transformed this machine under the skin and introduced more efficient engines, including a turbocharged 2.0-litre petrol that emits just 116g/km of CO2 in automatic form, making it a viable fleet alternative to diesel models.

Available with seven engines – varying from 150hp petrol and diesel models to rapid 252hp petrol and 272hp diesel options – the updated A4 gains extra power while emissions have fallen by up to 22%.

The A4 has also grown in size to offer a more spacious interior – with room for four tall adults to sit in comfort, although space for a fifth is limited – and looks slick and feels upmarket in entry-level SE trim, while pricier Sport and S-line trims feature extras such as satnav, upgraded audio systems and supportive sports seats.
