What is it like to drive?
Surprisingly easy. Yes, there is a sense of huge bulk when you first get in and pull away. But that disappears quickly once the vehicle is moving. The side mirrors might look a little small, but they do a decent job. For all close quarters manoeuvring, there are enough camera angles (18) easily to monitor the extremities and wheels. Parking is simple.
What about on the open road?
The HEV handles and turns like a car about five feet shorter, thanks to the active rear steering. Even though the rear steering angle is speed related, its smooth calibration makes it feel natural. The steering is finely weighted even though there isn't a huge amount of contact patch feel.
Braking is largely handled by the regenerative system, to try and capture back some of the kWs gushing out via the four wheels. There is a good amount of pedal feel allowing you confidently to trim speed without any weird change in braking power at any point in the pedal travel. Which is just as well when trying to stop 4,000kg+ of fast-moving metal.
Is it comfy?
The driving position is quite relaxed and yes, comfortable, with all key information appearing on the large central driver screen. An essential part of that is the new second-gen SuperCruise activation icon. First-gen SuperCruise was tricky to use, but a lot of those bugs have been sorted on this latest system.
Now it not only allows full hands-free driving, it also changes lanes automatically as and when it finds a slower moving vehicle ahead and a clear lane to one side of it. It doesn't work on every road – only those which GM has mapped – but that is still a big chunk of the US. It still needs to crack city auto driving, but it’s getting there.
