Based on the company's modular MQB architecture – which underpins an array of models from the Golf hatch to the Atlas large SUV – the stretched Tiguan features up to seven seats and a wheelbase that is 112mm longer than the short-wheelbase version already on sale in Australia.
The long-wheelbase version also gets the sporty rear bumper design of the recently-launched Tiguan 162TSI, which features a dual exhaust diffuser-style treatment, similar to those seen on the larger Atlas and recently-revealed 2017 Golf facelift.
Inside, a sliding second row allows easier access to the rearmost seats, while the Digital Cockpit driver's display and a new 'Car-Net' infotainment system – which features Apple CarPlay, Android Auto and MirrorLink compatibility – are also available.
Powering US-market versions of the long-wheelbase Tiguan will be a sole 2.0-litre TSI turbocharged petrol engine, developing 184 horsepower (137kW) and 300Nm of torque.
Drive is sent to the front wheels via an eight-speed automatic transmission as standard, with Volkswagen's 4Motion optionally available.
Other headlining features in the US-market version include a suite of active safety features including adaptive cruise control with stop and go function, forward collision warning with autonomous emergency braking (AEB) and pedestrian detection, blind spot monitoring with rear cross traffic alert and lane departure assist.
Seven seats will be standard on front-wheel-drive versions and optional on all-wheel-drive models in the US, with other extras including a panoramic sunroof and an electric tailgate.
The Tiguan Allspace has been confirmed for a local launch in the first half of 2018, though final details of the Australian-bound version are still to be revealed.
Unlike the US version, the long-wheelbase Tiguan sold here will offer a "selection of drivetrains from the current Tiguan" mated to the company's dual-clutch DSG transmission, as opposed to the American version's eight-speed torque converter.
Speaking with CarAdvice, Paul Pottinger, general manager for corporate communications at Volkswagen Australia, said the Tiguan Allspace will come with seven seats as standard with a "high level of spec promised".
Stay tuned for more Tiguan Allspace updates in the coming months.
