More power for light vans, more payload for VC trucks
• Changes to the Chrysler United Kingdom vehicle range which will be seen at the Commercial Motor Show include a high-compression, higher-power petrol engine for the Commer PB light vehicles; automatic-transmission options for the Commer Walk-Thru van range; weight uprating for the Commer VC 4 and VC 5 truck types; and the introduction of standard factory-finish-paint options for most Commer, Kanier and Dodge models.
The high-compression-engine option in the PB range will benefit light bus and caravan-conversion applications but will also be popular with operators of vans where the• extra performance from the higher power output promises to impreve productivity without loss of fuel economy.
