2003 Lexus HPX Concept

Lexus introduced its latest concept vehicle today at the New York International Auto Show. Known as the HPX, or High Performance Crossover, the vehicle combines the versatility of a luxury utility vehicle and the performance of a sports sedan in a sleek and stylish package.

The HPX concept was initiated and designed by Calty Design Research, Inc., Toyota’s California-based design center in Newport Beach.

The Lexus GS 430 luxury sport sedan platform provided technical inspiration for the HPX. The concept proposes the security of all-wheel drive with a dynamic form that yields utility and dramatic styling. The HPX is powered by a 4.3-liter 300-horsepower V8 engine and paired with a five-speed automatic transmission. It has an athletic chassis with height-adjustable suspension to match high-performance expectations. Premium levels of comfort and luxury complete the picture.

The HPX concept also serves as the first expression of a new Lexus design philosophy. This design philosophy is not a strict formula that will be used to calculate new forms and styles for Lexus. Rather, it is an idea that will be adapted in many forms to introduce more continuity to the Lexus line-up. The HPX incorporates key characteristics representative of the new approach that includes innovation, confidence, dynamic posture, intriguing elegance and the infusion of technology.

The interior is remarkably clean and uncluttered with a driver-oriented feel. The instrument panel uses advanced technology to allow drivers to customize displays and information to their needs. Readouts can be scaled, repositioned, and color-adjusted for individual preference. Small cameras situated on the side and rear of the vehicle feed their images to the front display.

A drive-by-wire steering system is employed and a single interface is used to navigate various control menus as well as the GPS navigation system.

Full volume bucket seats are provided for the front and middle rows, while a third row seat designed for children folds into the rear floor. LCD display screens deploy from the center console to provide DVD entertainment for the second and third row passengers.
