Chrysler has launched a new 2.4-litre petrol engine to replace the 2.0-litre petrol engine in the PT Cruiser, and added a cabriolet and a sportier GT special edition to the PT Cruiser line-up for 2005.

Chrysler UK will bring up to 100 2.4-litre PT Cruiser Cabrios into the UK during the year, but only in left-hand drive form.

The special edition GT is based on the 2.4-litre Touring and adds a body coloured rear roof mounted spoiler, sports suspension and 17 inch GT alloy wheels.

The new 2.4-litre petrol engine is a normally aspirated engine and EU4 emissions compliant. It produces 143 bhp and 158 lb ft of torque compared to the 134 bhp and 139 lb ft of torque of the outgoing 2.0-litre engine and takes the PT Cruiser to a top speed of 121 mph and 0-62 mph in 10.6 seconds.

The PT Cruiser Cabrio Limited features an all-new body structure that combines extra-large doors and a fully lined, electrically-folding cabrio roof. The full-leather, customised two-tone interior has a tip-and-slide front passenger seat for easy access to the individually styled twin rear seats. These seats can be split 50/50, or folded and tumbled to greatly extend boot space.

Available from December 2004, prices start at £12,995 for the Chrysler PT Cruiser Classic, £14,520 for the Touring and £16,020 for the top-of-the-range Limited. The special edition 2.4-litre petrol GT model, which comes with a manual gearbox only, costs £14,995.

The left-hand drive cabriolet, with five-speed manual or four-speed automatic transmission, will be available from March 2005 priced at £17,495 for the manual and £18,295 for the automatic gearbox.
