The all-new Lexus GS - which goes on sale in April 2012 - will be available with both hybrid and petrol engines.
The current GS is available only with a hybrid petrol/electric powertrain, after Lexus dropped the 3.0-litre V6 petrol model in 2009. A Lexus source told us: We perhaps pulled out of that market too early.
As a result, the new GS will be launched with an entry-level 2.5-litre V6 petrol model, called the GS250, which will provide a lower starting price for the range. Current GS450h prices start at 44,615, but the GS250 could drop below the 40,000 barrier.
There are currently no plans for a diesel model, despite press speculation suggesting otherwise. Lexus remains committed to hybrid technology and the new GS450h is expected to use an updated version of the current models powertrain, which combines a 3.5-litre V6 petrol engine with an electric motor, for a combined 341bhp output. The new GS450h is likely to have more power, but lower CO2 emissions and fuel consumption.
Lexuss LF-Gh concept car unveiled at the New York motor show in April 2011 gives a good idea of how the new GS will look. Only minor changes are likely, with less dramatic bumpers and conventional door mirrors and handles the main differences.
