Take your LEGO® Technic™ experience to a new level of realism: • Get unique experiences designed especially for each LEGO Technic AR model. • Enjoy realistic sound effects and lifelike features and functions. • Learn about robotics, engineering, rock sampling and more when you combine the AR app with the LEGO Technic NASA Mars Rover Perseverance (42158) model. • Explore LEGO Technic racing cars using the AR app to see the racetrack appear in front of you as you test your racing skills, play mini-games and beat your own record, and see trackside features like pitstops or grandstands appear (dependent on the model you are playing with). • Take the Yamaha MT-10 SP for a test drive in AR with throttle, brakes, gear shifting and driver dashboard, all based on the real Yamaha controls. See how the real vehicle or the LEGO model would look, life-size in your room, or use the x-ray view to see inside the motorcycle. Here are some models you can explore with the AR app… • LEGO Technic Formula E® Porsche 99X Electric (42137) • LEGO Technic Ford Mustang Shelby® GT500® (42138) • LEGO Technic NASA Mars Rover Perseverance (42158) • LEGO Technic Yamaha MT-10 SP (42159) … and the list keeps growing! (Remember that each of these sets is sold separately.) Each of these models comes with its own unique AR experience. Whether it’s the Yamaha MT-10 SP, the Formula E Porsche race car, the Ford Mustang Shelby GT500 or the NASA Mars Rover Perseverance, you’ll be able to put your skills to the test with augmented realism.
