Introduction

INEOS Automotive, the British carmaker known for its rugged off-road vehicles, is moving towards electrification. Founded in 2017 by Sir Jim Ratcliffe, INEOS initially focused on petrol and diesel-powered 4x4s, with its first model, the Grenadier, positioned as a successor to the classic Land Rover Defender. Now, the company is preparing to introduce electric and hydrogen-powered off-road vehicles as part of its low-emission strategy. This shift comes as the industry faces increasing pressure to reduce emissions and meet stricter environmental regulations while maintaining off-road capability.

The INEOS Grenadier

The INEOS Grenadier is a purpose-built, off-road 4×4 developed to fill the gap left by the classic Land Rover Defender. It is designed for adventure seekers, workers, and overlanders who require a highly capable vehicle. 

  • Traditional 4×4 Design – A boxy, utilitarian structure engineered for durability. 
  • Powertrain Options – Initially available with petrol and diesel engines, with plans for hydrogen fuel-cell and fully electric versions. 
  • Chassis and Suspension – Built on a ladder-frame chassis with solid axles for strength in extreme conditions. 
  • Interior – Function-first design with physical switches and a straightforward layout for ease of use. 

Electrifying a rugged off-roader presents challenges, including weight, range, and off-road performance. INEOS aims to overcome these through partnerships and engineering advancements.

INEOS and Electrification

INEOS has approached electrification cautiously, ensuring its vehicles retain serious off-road capability. Unlike manufacturers that have rapidly transitioned to battery-electric vehicles (BEVs), INEOS is balancing performance and durability, particularly in challenging environments. 

In 2021, the company partnered with Hyundai Motor Group to develop a hydrogen fuel-cell-powered Grenadier. A fully electric Grenadier was initially planned for production in 2026, but with the introduction of a range-extender option, production has been pushed back to early 2027 at the earliest. The INEOS Fusilier is now expected to launch in 2028.

Upcoming Electric and Hybrid INEOS Models 

INEOS Fusilier – First Electric INEOS (2028) 

The Fusilier will be INEOS’s first electric 4×4, available in two configurations: 

  • Battery-Electric (BEV) – A fully electric 4×4 with a projected range of 250-300 miles. 
  • Range-Extender (REx) – A hybrid system with a small gasoline engine acting as a generator to maintain battery charge when external charging isn’t available. This configuration caters to drivers who venture far from charging stations. 

The Fusilier will be slightly smaller and lower than the Grenadier, featuring a modern design. It will be built on a custom platform with a steel underbody and aluminium closures.

Hydrogen Fuel-Cell Grenadier 

INEOS is working with Hyundai to introduce a hydrogen-powered Grenadier, using technology similar to the Hyundai Nexo. The prototype leverages INEOS’s existing powertrain relationship with BMW to source the 115kW fuel cell and two 2kg hydrogen storage tanks. In its current form, it has a range of 200km (124 miles), which is expected to be trebled for production. 

Why Hydrogen? 

  • Faster Refuelling – Hydrogen vehicles can refuel in minutes. 
  • Lower Weight – Fuel cells weigh less than large battery packs, improving off-road agility. 
  • Zero Emissions – Only water vapour is emitted, making it a green alternative. 

INEOS unveiled a Grenadier Hydrogen Fuel Cell Technology Demonstrator at the Goodwood Festival of Speed in July 2023. This proves that hydrogen-powered 4×4 technology is ready for production, though commercial viability depends on refuelling infrastructure expansion. 

Fully Electric Grenadier – Challenges and Development 

Developing an electric Grenadier comes with key challenges: 

  • Weight Management – Large battery packs impact off-road balance and agility. 
  • Range Concerns – Off-road driving requires extended range, but charging infrastructure in remote areas is limited. 
  • Durability – EV components must withstand water crossings, mud, and extreme terrain. 

Potential solutions include lightweight battery materials, improved energy density, and rugged EV drivetrains tailored for off-road use.

What to Expect from INEOS’s EV Expansion 

  • More Electric Models – The Fusilier is the first step; additional EVs could follow after 2028. 
  • Hydrogen Growth – The partnership with Hyundai may establish INEOS as a leader in hydrogen off-roaders. 
  • Sustainability Focus – A shift towards EVs and hydrogen could reduce INEOS’s environmental impact. 
  • Charging and Refuelling Infrastructure – Investment in off-road charging and hydrogen stations will be crucial for adoption. 

INEOS Automotive is taking a strategic approach to electrification, offering battery-electric, range-extender, and hydrogen-powered options. This positions the company as a strong player in the growing zero-emission off-road vehicle market.
