Green Ncap tests 4 cars for families - Sustainable Mobility. Volkswagen's battery-powered proposal, the ID.7, combines generous external and internal dimensions with the efficiency of a compact car.
Three stars and a score of 51% for the Opel Astra 1.5 CDTi, a wagon equipped with the 8-speed automatic transmission. Green Ncap indicates how mileage increases on the motorway, and also considers the performance of the exhaust gas post-treatment system to be improved on shorter journeys with cold engine starts.
