The old adventurer has a fancy new tool in its off-road kit – but whether it’ll chart a course here comes down to price.

EVEREST-rated sleeping bag and tent, multi-tool, freeze-dried food but perhaps no need for a jerry can of fuel as you’ll be heading into the rough with a three-cylinder petrol engine with electric motor that’ll give a Toyota Prius a run for ultra-efficiency.

The announcement of plug-in hybrid versions of the Range Rover Evoque and Land Rover Discovery Sport remind this famous off-road brand is packing for new kinds of adventures these days.

This greater involvement with electric drivetrains won’t just touch into the small, more city-favoured cars. It is highly probable Land Rover is set to introduce new mild-hybrid six-cylinder diesel engines to the Range Rover and Range Rover Sport within a few months effectively spelling an end to the V8 diesel.

However, the big push starts with the smaller cars, just-revealed in the United Kingdom.

And set to show in New Zealand when exactly? Jaguar Land Rover New Zealand says it certainly has interest in the product – but not the price the maker is setting for it.

Says product manager Paul Ricketts: “We are currently in pricing negotiations with the central team on these models.

“The pricing we have at the moment does not allow for the models to be competitive in New Zealand.”

Exactly what premium those P300e variants hold is anyone’s guess, as UK pricing has yet to be made public.

These editions are the first to use Land Rover's new Premium Transverse Architecture, which allows them to use plug-in technology for the first time and despite perception about this drivetrain approach being a touch ‘lite’, the maker categorically assures it’ll survive exploration outings of the Ureweras and Central Otago.

The hybrid system combines a 149kW turbocharged three-cylinder 1.5-litre petrol engine with a 81kW electric motor fed from a 15kWh battery stack, tucked under the rear seats.

The combined power output of both cars is 230kW, with 540Nm of torque. That's good enough for the Evoque to achieve 0-100kmh in 6.1 seconds and the Land Rover in 6.6s.

Claimed fuel economy and emissions are an eye-opener. Just 1.4 litres per 100km with emissions of just 32g/km, while the slightly larger, heavier, Discovery Sport scores 1.6 litres per 100km and 36g/km of CO2. Both cars can travel for more than 60km on a fully-charged battery - 66km for the Evoque and 62km for the Discovery, both capable of speeds of up to 135kmh on battery power alone.

It’s a technology leap that has been tackled with typical Land Rover ingenuity. The engine is effectively an Ingenium four-cylinder with a pot lopped off the end, which makes it 37kg lighter than the donor.

The PHEV technology marks a major change in Land Rover's four-wheel drive technology. For the first time on a four-wheel drive Land Rover model, there's no transfer box, and no propshaft going to the rear wheels. Instead, the rear of the car uses Electric Rear Axle Drive (ERAD) tech. The electric motor drives the rear wheels at speeds of up to 135kmh, after which it's decoupled to reduce transmission drag and save even more fuel.

There's also a new brake-by-wire system which maximises brake energy recuperation, and an on-board 7kW charging system for topping up the battery. Both cars can rapid-charge from 0-80 percent in 30 minutes. From a domestic socket, charging takes six hours and 42 minutes, while from a 7kW home charger box, it takes one hour and 24 minutes to reach 80 percent.

When running in hybrid mode, the vehicle's electronics use Predictive Energy Optimisation (PEO) tech, which combines inputs from the steering, throttle, and brake as well as localised GPS data and the sat-nav destination to best juggle the mixture of petrol and battery power.

The engine drives the front wheels through an updated eight-speed automatic transmission.

Nick Rogers, Jaguar Land Rover Executive Director of Product Engineering assures the models still meet traditional requirements.

The drivetrain lends “fantastic all-wheel drive capability and the perfect blend of performance, depending on your driving style” while the cars maintain “the same awesome capability and composure with all-electric driving and stunning efficiency, both on- and off-road.”
