Like the hatchback, it rides on an all-new, lighter underbody – being less heavy allows for compact, more efficient engines as well as a size reduction for other components, like smaller brakes.This reduces the Astra Sports Tourer’s thirst for fuel, aided by improved aerodynamics which match the hatchback’s wind-cheating performance.Despite being lighter, the latest Sports Tourer’s structure is also more rigid, allowing engineers to fine-tune the handling to an impressive degree. It’s set to sate more enthusiastic drivers with its wieldiness just as the hatchback does.No surprise that the interior is as accommodating for passengers as the Astra hatchback: four six-foot tall adults will easily sit comfortably while the back seat accommodates three child seats – a rarity in a car that’s not a traditional MPV.Efficient engine rangeSave for the entry-level 1.4-litre petrol with 100hp, all of the other engines in the Vauxhall Astra Sports Tourer line-up are turbocharged.Well-equipped, simplified rangeAlmost mirroring its hatchback counterpart, the Vauxhall Astra Sports Tourer line-up consists of four trim levels – there’s no Energy grade for the estate range – but many of the features offered are more commonly associated with more expensive cars.TEST DRIVE TODAY
