Outside, the six year old car remains unchanged, including the classic Alfa grille and asymmetric registration plate.
However, inside the compact saloon and estate versions now offers a more upmarket ‘sports’ cloth upholstery for entry-level models and a choice of two colours of sports leather for higher specification models.
Chrome highlights to the dashboard and on the centre console complete the interior upgrade, while new equipment for the three standard trim levels will be available with all 2011 Alfa Romeo 159 models.
The three trim levels, Turismo, Lusso and TI, come with automatic climate control, cruise control, front fog lights, alloy wheels and a sound system as standard.
Lusso adds the leather upholstery, illuminated sports dials, rear parking sensors and larger 17" alloy wheels (Turismo comes with 16" alloy wheels).
At the top of the range, TI versions come with sports suspension, red brake callipers and an aluminium sports pedal. A redesigned leather-trimmed steering wheel and TI logos complete the sporty feel of the range-topping model.
Designed to provide an attractive, sporty alternative to traditional executive cars, Alfa Romeo has revamped the engine options to lower costs for business users for the 2011 model year.
The 2.0-litre, 136bhp diesel engine has been tweaked to comply with European emissions regulations and as a result, offers as little as 134g/km – one of the best performing saloons on the market in terms of emissions.
The engine is the least powerful in the Alfa 159 range, joining the 2.0-litre 170bhp and a petrol alternative, the 1.75-litre turbo petrol engine developing 200bhp.
The updated Alfa Romeo 159 saloon is available now from £22,500 for saloon versions. This applies to entry-level Turismo trim with the new 136bhp diesel engine.
Estate – or Sportwagon – variants start from £23,750 on-the-road and is available from Alfa Romeo dealerships in the UK.
