Currently in the early stages of development, the second-generation A45 is scheduled to go on sale in early 2019. It will be the flagship model for an extended range of A-Class models that will include a new plug-in petrol-electric hybrid.
Changes to the A45’s body structure mean that it will be marginally longer than today’s version and adopt a higher percentage of aluminium in a bid to retain a similar kerb weight. It will also feature an updated version of AMG’s M133-designated turbocharged 2.0-litre petrol engine and the multi-plate four-wheel drive system used in today’s model.
The reworked 2.0-litre four-pot engine will be given a series of changes that include revised fuel injectors, an altered turbocharger and subtle revisions to the combustion process. These tweaks are said to enable the engine to kick out up to 200bhp per litre — a figure that hints at more than a 20bhp increase in reserves at over 400bhp.
