Navara-based rescue vehicle on show in São Paulo, with exterior finish inspired by native bird species.

The Nissan Frontier Sentinel concept has been revealed at the São Paulo motor show, designed by the company's Brazilian design studio as a rugged rescue vehicle that can handle any terrain.

Finished in eye-catching Thunder Blue, the Frontier Sentinel is based on the standard Frontier dual-cab ute – known locally as the Navara.

Key features include two battery packs from the Leaf EV as auxiliary power sources, a modified tray to accommodate the batteries and a storage system, a take-off and landing platform for drones, and a strengthened rollbar spanning the sides of the cargo bed.

There's also a snorkel, bespoke light system, Electric Yellow accents throughout the exterior and cabin, along with special wheels wrapped in off-road tyres.

Nissan says the Thunder Blue exterior finish is inspired by the Brazilian hyacinth macaw, a native parrot of the central and eastern regions of South America, while the Electric Yellow highlights are inspired by electric circuits.

The Nissan Frontier Sentinel is the latest in a line of Navara-based concepts in recent months, following the Dark Sky concept revealed for the Hannover motor show in September.
