Peugeot’s 407 will have some tweaks, a new engine and a new trim level from next month.

The 2009 model includes a variety of interior and exterior enhancements and a new sat-ellite navigation system.

An HDi 140bhp diesel engine with CO2 emissions of 150g/km is also new, along with a new SR model.

The 407’s grille has been changed and the car’s rubbing strips are now body-coloured.

Inside, SE and GT models feature a piano black finish to the trim.

The 140bhp HDi engine will return 49.5mpg and complies with Euro V emissions standards.

A 2.0-litre Bioflex engine capable of running on E85 bioethanol will be available from November. 

The SR comes with either the HDi 110 diesel engine or the new 140 HDi unit.

The SR trim level fits below the SE trim and includes 16-inch alloy weels, Smartnav satellite navigation and Bluetooth.

Also now available are five new exterior colours – Moondust, Thorium Grey, Abyss Blue, Moroccan Red and Hurricane Grey.

It costs from £18,295.

The French company is set to unveil a new hybrid concept car at October’s Paris Motor Show.

The GT coupé is going under the working name of the RC and promises to be the missing link between the RC concept cars of 2002 and the 908RC revealed at the Paris Show in 2006.

The car will have four doors, four seats and potential power of 313bhp with CO2 emissions of just 109g/km.
