In a major breakthrough, Hyundai has introduced the Uni Wheel technology, a transformative approach to electric vehicle (EV) motor design. This innovation is poised to significantly reduce the size of electric motors, creating more spacious interiors for passengers and cargo.

Uni Wheel Technology Overview

The Uni Wheel, building on in-hub motor concepts, repositions specific drive components required by electric cars inside the wheel. While the power unit remains external to the wheel, the reduction gear is ingeniously relocated into the wheel hub, resulting in a notably smaller motor size. This pioneering design allows Hyundai to adopt a configuration featuring one small motor per wheel, departing from the conventional approach of a larger drive unit for the entire axle.

Key Features and Advantages:

• Independent Wheel Power: The use of a small motor per wheel enables independent power distribution, enhancing both performance and safety by allowing each wheel to respond autonomously to diverse road conditions.
• Gear Arrangement: Internal relocation of gears facilitates efficient power transmission without the necessity of a CV joint. This unique gear arrangement allows unrestricted movement within the hub, eliminating efficiency losses associated with operating at angles and boosting power delivery and driving range.
• Versatile Ride Height Control: Uni Wheel technology provides engineers with unprecedented flexibility in controlling the vehicle’s ride height. The absence of a fixed CV joint allows dynamic adjustments, enabling the vehicle to lower for aerodynamic highway driving or raise for increased ground clearance without compromising performance.
• Scalability: Uni Wheel technology is adaptable, accommodating wheel sizes ranging from four inches for personal mobility devices to 25 inches for larger vehicles such as cars and SUVs.

Future Applications and Production Timeline

Hyundai envisions the Uni Wheel technology being applicable to a diverse range of vehicles, from compact personal mobility devices to larger cars and SUVs. The company has conducted durability tests, indicating positive performance results. While the production timeline remains undisclosed, Hyundai has filed patents for the Uni Wheel in key markets, including Korea, Europe, and the United States.

Toyota revealed a newly-designed NASCAR Cup Series (NCS) Toyota Camry XSE race car that will debut in the 2024 NCS season. The Camry XSE Next Gen follows the Toyota Camry TRD Next Gen, which produced 18 victories and 25 poles during the last two seasons of competition.

Toyota, TRD (Toyota Racing Development, U.S.A.) and Calty Design worked together to ensure body styling characteristics replicated the recently unveiled 2025 Toyota Camry XSE as closely as possible. New features of the Toyota Camry race car include a distinctive hammerhead styling on the front facia with an upper grille slot that is tied into the updated slim and wide headlights.

The outside of the larger lower grille area also features C-shaped corner vents, while the hood features new character lines and new hood duct exits. The back facia of the car includes revised quarter panel styling and chamfered bumper corners on the back of the corner panels that blend into the rear bumper. These features, along with updated thinner taillights, give the new Camry race car a more sculpted appearance.

Toyota continues to be the only manufacturer in NASCAR to showcase three nameplates across the three national series – the Camry in the NCS, the GR Supra in the NASCAR Xfinity Series (NXS) and the Tundra TRD Pro in the NASCAR CRAFTSMAN Truck Series (NCTS). Since joining the NCS and NXS in 2007, Toyota has earned 180 NCS wins and three NCS championships along with 201 NXS victories and four NXS titles. And since its entry into the NCTS in 2004, Toyota has claimed 228 wins and nine Truck Series championships.
