The VP series was released in September 1991 with mainly cosmetic and feature changes to the outgoing VN Series Commodore. The 3.8 litre V6 and 5.0 litre V8 engines from the VN were carried over, but the V6 engine received various revisions that improved its refinement and noise. Semi-trailing arm IRS became standard on Calais and Commodore SS models and became an optional extra on lower-end models. This new suspension drastically improving ride and handling over that offered by the live rear axle. ABS brakes were also introduced in the VP range as an option on Series 1 Calais and Commodore SS models, and on most models with IRS for Series II versions. Additional security features were introduced across the range, including an ignition-disabling device and a driver's door deadlock. Power mirrors were also a standard feature across the model range. The VP Calais was also sold in Thailand, with 3.8 V6 version, later it used an Opel 2.6-litre C26NE inline-six Dual Ram engine.1991 model VP Holden commodore sedanLion and Stone badge on bonnet , Holden badge left hand side boot , Lion and Stone badge on boot centre, Commodore executive on boot right hand sidevp holden, vehicle, car
