The most potent version of the Brit brand’s V8 is now a general issue item optimally delivered in a new hero hue.

BLACK news is making headlines for Range Rover - and for brand fans it’s positive story making.

Having made the previously limited edition Range Rover Sport SV a permanent fixture in the line-up, Jaguar Land Rover has also now announced that type’s epic tuned-up 4.4-litre (BMW-shared) V8 powertrain will also avail in the full-sized Range Rover.

Output in the bigger lugger is 458kW, a whopping amount for this vehicle though down a tad on the Sport, which runs with 477kW across two variants.

The more expensive of the Sports and the Range Rover SV configure in a Black theme than is entirely literal … the cars with trim type go full Spinal Tap 'None More Black'.

The national distributor having rushed to share news about the models suggests it will be seeking to bring in all three.

Pricing and availability here has yet to be clarified, but in the United Kingdom the SV Sport costs around $318,000,. The more focussed Black edition loading on a further $34k. There’s no price, yet, for the Range Rover SV Black (pictured).

JLR created SV as the pinnacle of the Range Rover Sport lineup; while the two body shapes have different power outputs, torque is set to a common 750Nm. SV models have a top speed of almost 300kmh. And the SV Range Rover Sports will crack 0-100kmh in 3.3 seconds.

The Black treatment is, the brand says, to “celebrate the timeless appeal of an all-black aesthetic.”

It means a Narvik Black body and a full Narvik Gloss Black Exterior Pack. There's also a black-painted carbon-fibre bonnet and gloss-black forged alloy wheels with gloss-black brake calipers and gloss-black quad exhausts. Even the ceramic SV badge on the boot has been blacked out.

Inside, the Sport there's Windsor Leather for the seats finished in, inevitably, Ebony while there are 'Gloss Grand Black' finishers for all of the interior trim.

The full-sized Range Rover, meantime, goes for leather seats in a 'near Analine' finish and for the first time it gets single-panel seat covers which feature fewer stitches and seams. There are black birch wood veneers and black ceramic finishers for the likes of the gear shifter.

The big boy car also something of a breakthrough in in-car entertainment tech - Land Rover has developed what it calls a 'world first' Immersive Sensory Floor technology for the stereo system.

Basically, it's a series of under-floor transducers, which create a haptic sensation through the floor mats, which Land Rover says: “creates an expansive and immersive listening experience, allowing occupants to physically feel the music.”

The biggest SV also comes with another world-first - recycled tyres. The SV gets Pirelli P Zero tyres with 'more sustainable material content', which includes more than 70 percent bio-based and recycled materials such as silica from rice husks, recycled steel and plant-based oils and resins. Pirelli also says that the new P-Zero tyres use certified natural rubber, as overseen by the Forest Stewardship Council, a charity that seeks to prevent deforestation and protect the Earth's trees.
