2021 Hummer EV to get 'crab mode' four-wheel steering

The 2021 Hummer EV will be capable of driving diagonally thanks to a 'crab mode' four-wheel steering system, GMC has revealed. In a promotional video posted to YouTube, the General Motors truck division demonstrated the technology alongside a less-than-cryptic slogan “Sometimes the biggest leaps forward are actually diagonal”. However, the clip indicates the feature will be an optionional extra, rather than fitted as standard.
