Chrysler has expanded the PT Cruiser lineup once again for 2005. There are now eleven PT variations. The Dream Cruiser and Limited Platinum Edition have both been dropped from the lineup, but four convertibles and two Signatures models have been added. The new two-door convertible is available with the Base, Touring, and GT trim levels, and all three PT engines are available with this body style. Chrysler's 2005 Signature Series package was available on several different models, including the PT Cruiser, 300, Sebring, Pacifica and Town & Country. This package commemorates Chrysler's long history, and bundles several appearance and luxury features at no additional cost. Upgrades on the PT include a navigation system, chrome trim, a moon roof, Sirius satellite radio, and two-tone leather seats. This model is available with two engine options. The Base wagon, Base convertible, Touring wagon, Touring convertible, Limited wagon, and Signature Series wagon are all powered by the original 2.4 liter DOHC inline four, which delivers 150 horsepower and 162 pound-feet of torque. The Touring Turbo Covertible, Limited Turbo wagon, and Signature Series Turbo wagon house the mid-level engine option: a turbocharged version of the 2.4, which now makes 180 horspower and 210 pound-feet of torque. The GT and GT Convertible are the only two PT Cruisers to boast a 220 horsepower version of this engine, which sends them from 0 to 60 in just 6.7 seconds.
