Bentley's first electric car has been tested from minus 38 to above 40 degrees C, with a 625 kg battery put through fire and impact trials.
Bentley says development prototypes and pre-series versions of the Torcal, its first electric car, have covered more than 1,000,000 kilometres in climates from minus 38 to above 40 degrees Celsius. The company also detailed battery safety tests, including a two-hour fire-resistance requirement, and a software cycle that delivers a new build every six weeks.
Before Bentley's first electric car reaches customers, its development fleet has already clocked more than 1,000,000 kilometres. Bentley says prototypes and pre-series Torcals racked up that distance worldwide, and it has now set out how the car was engineered before the camouflage comes off.
The test programme ran from minus 38 degrees C in Swedish winter conditions to more than 40 degrees C in desert heat. On altitude, the cars went from sea level to more than 14,000 ft at Pikes Peak in Colorado. Bentley says the demands of different global markets shaped the work too.
Virtual cars first
Engineers leaned on Extended Reality more than on any previous Bentley. In the company's XR Hub, the Concept Validation team built a complete digital Torcal, with adjustable seating positions, working controls and a cabin environment, so people could judge ergonomics before any physical parts existed. Bentley says this shortened development and cut waste.
Physical checks followed. At the Physical Design Confirmation stage, more than ninety per cent of the Torcal's parts were available to assess fit, clearance, serviceability and build quality. Laser scanning compared real components with CAD data, and slow-build exercises mimicked production conditions to test assembly and flow.
Electrical and software work
Bentley calls the Torcal's electrical programme one of the most ambitious in its history. Three specialist teams covering electrical architecture, software integration and validation worked together continuously. A new software integration level arrives every six weeks, and each is checked in laboratories and in real vehicles before the next begins.
Battery safety
The battery has an energy density above 180 Wh/kg and weighs approximately 625 kg. Beneath it sits a composite impact shield that protects the cells and associated components from strikes to the underside. Bentley says it meets global safety standards through a programme of validation and regulatory tests, including:
- a two-hour fire-resistance requirement, with no fire propagation or explosion in a thermal incident
- underside impact testing, in which a 30 mm steel projectile of about 111 grams hits the enclosure at more than 100 mph
- salt-spray corrosion exposure and wider environmental and durability checks
Should the battery suffer serious damage, Bentley says the car is engineered to protect occupants for as long as possible.
Disguise strategy
Prototypes spend years hidden. Some wear graphic wraps designed to confuse the eye and defeat cameras, others carry temporary panels that hide key design features, and the approach changes with each test phase. Bentley says the camouflage is now being removed from the development fleet as the Torcal moves towards customer deliveries.
