Mega-G+ McLaren F1 MCL38 #81 AU2024 HO Slot Car

Meet the McLaren F1 MCL38 #81 Austin Chrome Edition—pure F1 attitude.

Part of McLaren Racing’s Chrome Shines Again campaign, it blends heritage-inspired chrome with the edge of a modern F1 contender. Finished in McLaren’s signature orange and black this special Austin edition pairs head-turning style with proven performance from the championship-winning 2024 MCL38 platform.

Built around a 1.6-liter V6 turbo hybrid and Mercedes-AMG F1 M15 E Performance power unit, the MCL38 delivers elite speed, precision, and efficiency.

Compared with the 2023 car, the MCL38 pushed forward with improved front suspension geometry, revised sidepod and engine cover shaping, underfloor development, and stronger aerodynamic efficiency—changes aimed at boosting mechanical grip, tire life, and low-speed performance.

Driven by Oscar Piastri in the 2024 Austin Grand Prix, car #81 brings real event pedigree to this chrome special.

The result: a sharper, faster, more refined evolution of McLaren’s 2023 car—wrapped in one of the most memorable liveries of the 2024 season.

The specialized, targeted chrome detail is one of the newest editions to the ever-evolving design capabilities of AFX. Looks and personality? This McLaren MCL38 is truly a double threat, it also happens to be a massive thrill to race.

Chassis Type: LONG (1.7”) Mega G+ Wheelbase

Mega G+ CHASSIS

This new Mega G+ chassis doesn’t just go faster or handle better than the competition. And it doesn’t just have the ultra-low, narrow dimensions of the original Mega G to continue the reign of the most realistic HO cars on earth. It’s smoother, more consistent, and more intuitive than any car we’ve ever built.

We wanted wheel to wheel racing, lap after lap, the feel of driving a real car. But we couldn’t do it by just changing the chassis. We had to create a whole new system…
