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.
The idea this time round with the Corsa is to strike a better balance between sportiness and comfort, thanks to a re-designed body shell and new aluminium engines. There are lighter underpinnings too, based on the new Common Modular Platform (CMP) platform this car shares with the latest Peugeot 208. Despite this, this fifth generation model is slightly larger than its predecessor, with its bigger body and longer wheelbase delivering more interior and boot space from this five-door-only model. The smarter body panels are still fashioned from the usual range of high-strength steels, but it's all been stitched together in a more weight-conscious manner, saving 40kg over the outgoing Corsa.
Visually, the standard Corsa is virtually identical to the electric version, with the exception of different alloy wheel designs. An exterior highlight that Vauxhall is particularly proud of it's the fact that this is the first car in the class to feature adaptive glare-free full-LED headlights - the brand's 'IntelliLux LED Matrix' package, the kind of thing previously restricted to much larger cars. Inside, all Corsas have identical cabins, which centre around a new touchscreen infotainment system on the dash. Two set-ups are available to buyers: a seven-inch Multimedia Navi system or top-spec 10-inch Multimedia Navi Pro.
If you'd got used to Corsa pricing for base models being in the £11,000 to £13,500 bracket (which is where it's been in recent times), you might need a cup of hot sweet tea after perusal of the figures being asked for this fifth generation French-inspired version, which start from around £15,500 for the feeblest 1.2-litre base-spec petrol variant. And even if you avoid the all-electric Corsa-e, it's still possible to pay as much as £25,000 for the ritziest-trimmed petrol model. Five doors are now standard (which partly explains the price rise), the three-door body style of previous models being deemed no longer necessary. For the Corsa-e, you're looking at needing to find around £26,000, though from that, you can deduct a £3,000 government plug-in car grant.
There are four core trim level options for the Corsa this time round - 'SE', 'Sri', 'Elite Nav' and 'Ultimate'. Go for the 'SE' or 'Sri' variants and there are interim 'Nav' and 'Premium' options. You can have the 'Elite Nav' model in an upgraded 'Elite Nav Premium' state of spec too. It's all quite complex. Simpler to comprehend is the need to pay a premium for auto transmission - an extra £1,730 on petrol models only. Even the most basic 'SE' derivatives are quite well equipped, fitted with 16-inch double spoke alloy wheels, a 7-inch touch-screen radio, a leather flat bottom steering wheel and LED Headlights with LED daytime running lights.
Huge efforts have gone in here to improve running cost efficiency by saving weight. As a result, expect the 1.2-litre PureTech petrol variants that many will want to be very acceptably clean and frugal. With the 100hp model, you can expect to manage around 45mpg on the WLTP combined cycle and return a CO2 reading not much over 100g/km, which is pretty good going for a car in this segment. The 1.5-litre diesel version of course does much better. Over 60mpg on the combined cycle should be eminently achievable, along with a sub-100g/km of CO2 reading.
But of course if you're really interested in ecological efficiency, there'll be just one variant of this car that'll interest you, the all-electric Corsa-e. For this derivative, Vauxhall claims a WLTP-rated driving range between charges of 211 miles. And fast charging at the rate of 100kW is available via a CCS socket hidden behind the fuel cap, with an 0-80% charge achievable in around 30 minutes. If you install a wallbox at home, you can recharge the battery from empty in around five hours if you have an 11kW electricity supply - or in around eight hours with a 7.4kW supply. Bear in mind that the Corsa-e is around 350kgs heavier than the ordinary version.
Ultimately, what we're looking at here is a Corsa that can. It can be fun to drive. It can deliver a big car feel. And it can stack up well on the balance sheet. It's a small Vauxhall for which no apologies need to be made. All that will worry obvious supermini rivals. After all, this model's predecessor lacked a little in all of these areas, yet still racked up very respectable sales against them. This MK5 version's still very competitively priced, but has become a contender in this segment that sells on more than just sheer value.
It's not perfect of course. It doesn't lead its class in terms of either space, efficiency or driving dynamics. And more work is still needed under the bonnet to deliver an engine range in which all the options are as good as the mid-range three cylinder turbo petrol unit. The key though, is that this Vauxhall is now there, or thereabouts, in the three key areas I've just mentioned. Add to that the wide model line-up and the likely deals on offer and you've a supermini that more than ever, needs to remain high on any family's shopping list.
