Quoting Autocar:-
When the Mercedes GLC arrives in the UK later this year, we’ll be graced with a diesel-only engine line-up – initially comprising two four-cylinder oil burners with either 168bhp or 201bhp.
We’ve already driven the higher-powered diesel but, if you want a petrol – or indeed a hybrid – you’ll need to wait a little longer. While parts of Europe, China and the US will get a 2.0-litre petrol GLC 250, such an engine isn’t even earmarked for the UK. Bosses have confirmed this GLE 350e plug-in hybrid will join the range though, albeit not for at least 18 months.
Other sources would indicate that the USA will get a turbocharged petrol version GLC 300 and GLC 300 4MATIC featuring a turbocharged 2.0-liter four-cylinder engine that develops 241 bhp (179 kW) and 273 lb-ft (369 Nm) of torque.
MB seems determined that UK buyers all remain driving diesels? If impending legislation dictates diesel engines are eventually going to be banned from inner city areas this policy might push potential buyers towards other manufacturers?
