First drive in the plug-in-hybrid VW Passat GTE.
Powered by Volkswagen’s turbocharged 1.4-litre four-cylinder petrol engine developing 164bhp and a 9.9kWh lithium ion battery giving pure electric range of around 30 miles - 50 kilometers.
Due to the ingenious packaging in the range of VW's the interior in the petrol. diesel and plug in hybrid variants is identical, all rather clever stuff.
As for fuel economy, it depends who you ask. Anywhere between the claimed economy of 148.7mpg and 44g/km CO2 emissions, to a probably more realistic 100mpg-ish would be feasible from my short experience.
