The 2003 Lexus HPX Concept was designed by a studio in Newport Beach, California, with the aim of defining the future philosophy of Lexus vehicles. This concept was intended to represent the evolution of luxury crossovers, showcasing the core values of speed, style, and prestige that Lexus aims to embody in its cars. The HPX stands for High Performance Crossover, and it was envisioned to fill the gap between the compact RX330 and the larger GX470.
Built on the platform of the GS430 sedan, the HPX features a 4.3-liter V8 engine producing 300 horsepower and is equipped with permanent all-wheel drive, paired with a five-speed automatic transmission. Designed primarily for the North American market, the interior accommodates seven passengers. The first two rows have individual seating, while the third row is a flat seat suitable for small children. The rear seats can fold flat to create more cargo space.
While the HPX's interior was more about showcasing design ideas than practicality for production, it featured some intriguing elements. The steering wheel had a unique design and functioned differently than traditional steering wheels, signaling electric motors instead of directly connecting to the wheels. The center console boasted a large color display that provided customizable information from the car's sensors and systems, akin to a computer interface. Rear passengers enjoyed a DVD system with LCD screens, ensuring entertainment for everyone.
In terms of design, the HPX appeared light and dynamic, highlighted by its impressive wheel size—21-inch wheels with 265/50 tires in front and 295/45 in the back. The concept also featured advanced lighting solutions, including matrix-style headlights that added a high-tech look, though their functionality was uncertain. The car replaced traditional side mirrors with small cameras, offering a modern touch. Additionally, the rear doors opened in a unique way, a nod to luxury design trends seen in brands like Rolls-Royce.
As of now, there are no confirmed plans for the HPX to go into production, but its design hints at Lexus's intent to remain competitive in the luxury crossover market. If Lexus were to move forward with the HPX, they would likely need to address practical features like a conventional steering wheel and functional bi-xenon headlights to meet consumer expectations.
