INEOS says the interior of the Grenadier is “designed on purpose, to deliver the space, practicality and versatility owners need from a hard-working 4X4. Starting from a clean sheet, the design incorporates the modern technology and comfort expected of a vehicle for the 2020s and beyond”.

“When we started thinking about the Grenadier’s interior, we looked carefully at modern aircraft, boats and even tractors for inspiration, where switches are sited for optimal function, regular controls are close to hand, auxiliary ones are further away,” said Toby Ecuyer, Head of Design. “You can see the same approach in the Grenadier: the layout is functional and logical, designed with ease of use in mind. It has everything you need and nothing you don’t.”

Toggle switches and dials on the centre and overhead consoles are widely spaced and clearly labelled. Auxiliary switches have been built in, pre-wired to support the addition of winches, work lights and other accessories.

INEOS says that advanced technology is included only where it benefits functionality and usability. The infotainment system is accessed via a 12.3-inch touchscreen, or by using a rotary dial. The Apple CarPlay and Android Auto integration means users can rely on smartphone navigation. And the off-road pathfinder navigation system allows drivers to programme, follow and record their route via waypoints, when roads and tracks are left behind.

Hard-wearing surface materials are used throughout. Drain plugs in the rubber flooring and wipe-down upholstery mean the interior can be hosed out. Water-resistant anti-stain Recaro seats provide ergonomic support and comfort on or off the road. Carpets and leather upholstery will be available for those aiming to leave the mud and sand outside.

There is a dry storage box under the rear seat, a lockable central console cubby box, and secure side-mounted storage in the rear load area. There is also scope for individualisation, with a wide range of interior options and accessories to help each owner customise the Grenadier.

Dirk Heilmann, INEOS Automotive’s CEO, said: “Inside and out, the Grenadier has been designed to do a job – to get people and their kit where they want to go in comfort, in control and with no fuss. It just works.”

130 second-phase Grenadier prototypes are currently half-way through their target of 1.8 million kilometres (1.1 million miles) of gruelling testing around the world. Next stage: the dunes of Morocco.

Reservations will open from October 2021 and deliveries will start from July 2022.
