The passenger compartment of the G70 remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Genesis showed that a similar level of protection would be provided to the upper legs of occupants of different sizes and to those sitting in different positions. Analysis of the deceleration of the impact trolley during the test, and of the deformation of the barrier afterwards, revealed that the G70 would be a benign crash partner to other vehicles. In the full width rigid barrier test, protection all critical body areas was rated as good or adequate, with the exception of the pelvis of the rear dummy.  The pelvis of the dummy slipped under the lap section of the seatbelt during the test, a phenomenon known as ‘submarining’ and the score was penalised for this and protection of this part of the body rated as poor. In the side barrier test, representing an impact by another car, protection of all critical body areas was good and the G70 scored maximum points. In the more severe side pole test, protection of the chest was marginal and that of other body areas was good. Limitation of occupant excursion - the extent to which the occupant is flung to the other side of the vehicle in a side impact - was rated as adequate. The G70 is equipped with a centre airbag to protect against occupant to occupant injuries in side impacts. The airbag performed well in Euro NCAP's tests, with good protection of the dummies' heads. Tests on the front seats and head restraints demonstrated good protection against whiplash injures in the event of a rear-end collision. A geometric assessment of the rear seats indicated marginal whiplash protection. The G70 has an advanced eCall system which automatically alerts the emergency services in the event of a collision, and multi-collision braking to prevent secondary impacts.

The contour of the rear seat of the G70 meant that it was not possible assess dynamic child protection in the full-scale crash tests.  Accordingly, the child dummies were not used in the frontal offset and side barrier impacts and additional tests were performed to establish the dynamic performance in these impacts.  These tests showed that, in both the frontal offset test and the side barrier impact, protection of all critical body areas was good for both the 6 and 10 year dummies and the G70 scored maximum points in this part of the assessment. The front passenger airbag can be switched off to allow a rearward facing child restraint to be used in that seating position. All of the child restraint types for which the G70 is designed could be properly installed and accommodated.

The G70 has an 'active' bonnet: sensors in the bumper detect when a pedestrian has been hit and actuators lift the bonnet, creating more clearance to hard components in the engine compartment. Genesis showed that the system worked robustly for different pedestrian statures and across a wide range of speeds and, accordingly, the bonnet was tested in the raised, deployed, position. Protection was good over almost all of the bonnet surface. The bumper provided good protection to pedestrian's legs at most test positions. However, protection of the pelvis was mixed, with good protection at some test points and weak protection at others. The G70's autonomous emergency braking (AEB) system detects vulnerable road users like pedestrians and cyclists, as well as other vehicles. In tests of the system's response to pedestrians, performance was rated as adequate. The system's response to cyclists was good, with collisions being avoided or mitigated in most test scenarios.

The G70's autonomous emergency braking (AEB) system performed well in tests of its reaction to other vehicles, with impacts avoided in almost all cases. A seatbelt reminder system is standard for all seats and the G70 is also equipped with 'Driver Attention Warning', which monitors steering inputs for patterns which are characteristic of a fatigued or inattentive driver. Lane assistance is provided by 'Lane Keep Assist' which corrects the car's path if it is drifting out of lane and which also intervenes in some more critical situations. A speed limit information system uses a camera and digital mapping to identify local limits, allowing the driver to set the limiter appropriately.
