ORDERING has opened for the flagship engine version of the new Renault Laguna.

The engine is available on three trim levels: Dynamique, Dynamique S and Initiale, with on-the-road prices ranging from £19,150 to £23,900. The car which will develop a maximum of 175 horsepower and deliver combined fuel economy of 43.4 mpg in the hatchback version.

The flagship 2.0 dCi 175 is the first of several new engine variants to appear during 2008.

The new engine is available on both Hatch and Sport Tourer variants of New Laguna, from Dynamique trim level upwards. Prices for the six versions range from £19,150 to £23,900, a £750 price difference from the equivalent 2.0 dCi 150 versions. Initially available in the GT version of the former Laguna, Renault's 175 horsepower common-rail engine continues to be one of the most powerful two-litre diesels in its class.

The hatchback can accelerate from 0 to 62 mph in 8.7 seconds (8.9 seconds for Sport Tourer), before going on to a top speed of 137 mph (134 mph for Sport Tourer).

In spite of the power on offer, it emits 172 grams CO2 per kilometre (174 grams for Sport Tourer) due to its standard particulate filter. Renault says combined fuel economy is 43.4 mpg (42.8 for the Sport Tourer version).
