INEOS has revealed the production ready interior of its Grenadier 4x4 for the first time - and says it can be hosed out if it gets too mucky from off-roading.

The spiritual successor to the now defunct classic Land Rover Defender, the Grenadier also has drain plugs in the floor, rubber flooring and wipe down upholstery - although plusher carpets and leather covered seating will be available.

"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.

He added: "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.

Advanced technology is included only where it benefits functionality and usability, says Ineos.

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 which will always be up to date. 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.

Stowage space has been maximised, with 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 to best perform its role.

No fewer than 130 second-phase Grenadier prototypes are currently half-way through their target of 1.8 million kilometres 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.
