We can see that this sab easily accelerates, With several smooth and full throttle accelerations. This car is (almost) fast enough to keep up with an Porsche Panamera GTS, you may also see in this video. However, this is a station wagon car, but very fast SportCombi, which is easily achieved 240 km/h (150mph).
Also, this is perhaps the best angle to record video, we can see the road in front of car, but also the acceleration:
