Like its Opel, Vauxhall and Holden siblings, the Regal mainly differs from the Insignia Grand Sport / Commodore aesthetically with the now trademark waterfall grille and tri-shield logo replacing the blitz and lion logos as well as the honeycomb grille.
To be built alongside the Opel derivative in Germany and no longer in Canada, the Sportback designation also sees the Regal adopting a fastback profile for the first time compared to its sedan only predecessor, while the Tour X heralds the return of a station wagon Buick since the Roadmaster Estate ended production in 1996.
As previously reported, the Regal will only be available with a 2.0-litre turbo engine making 184 kW and 353 Nm of torque, although this increases to 400 Nm when specifying it with the optional all-wheel drive system. A brand new nine-speed automatic gearbox is standard with the former engine and an eight-speed self shifter with active twin-clutch diff on the all-wheel drive.
Pricing has yet to announced although buyers will be able to choose from four trim levels; base, Preferred, Preferred II and Essence.
