Vauxhall is replacing its core engine range, with three new engines that it claims will offer industry-leading economy and emissions.
Leading the new engines will be a 1.6-litre turbocharged petrol engine, which gets stop-start technology to help cut CO2 emissions by 13% compared with its predecessor's.
The four-cylinder engine will be available in various outputs of up to 197bhp up 20bhp on the current 1.6T with maximum torque of 221lb ft from 1700rpm. Vauxhall says it will be quieter than the engines it replaces and will be available across a number of model ranges.
There'll also be a new version of the company's 2.0-litre turbo, with a 276bhp unit destined for the new Astra VXR.
More details will be released on the full range of new diesel and petrol engines as they're launched over the coming 12 months.
