Engine-wise, there are two petrol units and a single diesel to choose from. Ideally, you'd want to avoid the base 75PS 1.2-litre petrol unit, which can only be had with 5-speed manual transmission. And go instead for the more modern three cylinder, direct injection turbocharged 100PS 1.2-litre petrol powerplant your dealer will prefer to point you towards. Here, there's a gutsier 205Nm of torque, which will mean easier mid-range overtaking and less of a need to 'row' the car along with the 6-speed gear lever in town. Alternatively with this 100PS drivetrain, there's the option of an auto transmission - and a very sophisticated one with 8-speeds which includes steering wheel paddleshifters.
The minority-interest Corsa engine option is a 1.5-litre 100PS diesel which will be a rare sight, but might make sense if you habitually undertake longer distances in your supermini, thanks to a plump 250Nm torque output. All the engines on offer are helped in their task by a significant weight reduction this time round - Vauxhall says it can be as much as 10%, which is quite a lot in supermini terms. Base-spec variants can now weigh as little as 980kgs. As for the all-electric Corsa-e version, well just one variant of that will be available featuring a 50kWh battery mated to a 100kW electric motor, this confection developing a healthy 134hp.
