Holden is using the name ‘Alloytec’ for its two new versions of the double overhead camshaft, four valves per cylinder engine, which develop 175kW and 190kW. They replace a pushrod, Buick-designed V6 dubbed ‘Ecotec’ in recent years and come with revised four- and new five-speed automatic transmissions.
Holden has also upgraded the US-built 5.7-litre V8 offered as an option in the Commodore and in the long wheelbase luxury WL-series Statesman and Caprice spin-off models.
Apart from minor interior and exterior styling changes, the new range features electronic stability program (ESP) on some V6-powered models for the first time on Australian-manufactured sedans. The system also includes corner brake control and electronic brake assist.
The Caprice and Statesman are the first Australian-made vehicles with LED rear lamps. The Caprice has also gained a tyre pressure monitoring system.
