Jaguar is doing all sorts of things to promote its I-Pace and the latest marketing stunt is meant to showcase the electric crossover’s real-life driving range.

The automaker had the I-Pace cover the 229-mile (369-km) distance from London to Brussels, with part of the trip including driving through the Chunnel’s service tunnel.

With its 90-kWh battery fully charged, the I-Pace started its journey on London’s South Bank and headed for the Channel Tunnel terminal at Folkestone. However, unlike all vehicles that cross the tunnel on trains, Jaguar’s I-Pace got special permission to drive the 31-mile (50-km) distance under the sea through the service tunnel.

With Jaguar engineer Stephen Boulter behind the wheel, the I-Pace emerged safely out of the tunnel at Calais and continued the trip eastward, arriving in central Brussels with a remaining battery charge of eight percent — enough to cover an additional 32 km (20 miles).

The Jaguar I-Pace’s claimed driving range is 292 miles (470 km) according to the WLTP cycle. The remaining battery charge might not have been enough to reach that figure, but the attempt proves the electric crossover can get quite close to it. One must also take into account the fact that the I-Pace encountered rush-hour traffic in the summer heat on its way to Brussels.

To ease range anxiety, the vehicle’s navigation system takes account of route topography and driving style when calculating range. As a result, it can suggest the most energy-efficient route available. In case the destination cannot be reached, it will alert drivers and help them find charging stations within range. Jaguar claims a 100kW DC rapid charger will add up to 100 km (62 miles) of extra range in just 15 minutes.
