Land Rover’s most luxe vehicle is about to get a lot more exclusive.

The British 4×4 specialist has just unveiled the Range Rover SV Ultra, a new top-of-the-line version of is most beloved models. The special edition features more exquisite details than ever before and a boundary-pushing audio system—but it will available by invitation only.

There are few vehicles more synonymous with luxury over the last half century than the Range Rover. The SV Ultra, which, as the name may have given away, will sit above the SV and SV Black in the model lineup, aims to take things to another level with a host of upgrades, including unique finishes and premium materials, that combine to make it the cushiest Landy yet.

The upgrades, at least from the outside, are surprisingly subtle. The range-topping variant is available in an exclusive finish dubbed Titan Silver, which resembles liquid metal thanks to a combination of fine aluminum flake and advanced pigment technology. The magnificent hue is complemented by Satin Platinum Atlas and Silver Chrome accents on the trim and badging. Rounding things out is a set of 23-inch alloy wheels finished in Platinum Silver and secured by the automaker’s new center caps.

The difference between Range Rovers becomes a little clearer inside the SV Ultra. The cabin is covered in duo-tone Orchid White and Cinder Grey Ultrafabric upholstery. The luxe, leather-free material features laser-crafted patterns and combines with rattan palm veneer and an open-poor finish to give the space a more cohesive look and feel. But the headline feature of the interior what Land Rover is calling the world-first SV Electrostatic Sound system. The setup uses 21 lightweight electrostatic speakers integrated into each “Body and Soul” seat and other areas of the cabin, like the headliner and floor, to turn the vehicle into a concert hall on wheels.

The Range Rover SV Ultra will be available with two powertrains, a hybrid-assisted 3.0 flat-six that makes 454 hp and a 4.4-liter V-8 that makes 519 hp, at launch, and an all-electric setup later down the road. No pricing has been announced, but something well north of the SV’s $219,500 starting price seems likely. Regardless of the price, you’ll have to wait for an invite from Land Rover itself if you want to buy the SUV.
