While today's SUVs chase futuristic styling and ever-more-complex technology, Ronnie Fieg and Kith chose a very different path. Working with BMW, the fashion label transformed a 2000 E53-generation X5 into a mechanical masterpiece by replacing its original engine with a naturally aspirated 5.0-liter S85 V10.

The SUV measures 183.7 inches / 4.67 meters long and weighs an estimated 4,740 lbs / 2,150 kg. With forged pistons and custom tuning, the V10 produces around 500 hp / 507 PS. Even more remarkable, the engine is paired with a genuine three-pedal manual transmission while retaining the factory all-wheel-drive system.

Inspired by the legendary V12-powered X5 Le Mans prototype, the build also features a wider stance, understated front aero and an M5-derived 9,000-rpm tachometer integrated into the dashboard.

Could a V10-powered classic SUV become a future collectible? Would you take this naturally aspirated monster over a modern turbocharged V8? And is this exactly the kind of mechanical character today's SUVs are missing?
