Well, this was unexpected. A couple of years ago, the Porsche 911 GT2 RS made its public debut at the E3 gaming conference in Los Angeles to coincide with the announcement of Forza Motorsport 7 for Xbox One. This year, however, a life-size McLaren Senna replica built from nearly half a million Lego bricks was brought on stage to announce a surprise new Lego-themed expansion for Forza Horizon 4.

The expansion lets you live out your childhood fantasies by letting you drive Lego Speed Champions versions of cars including the McLaren Senna, Ferrari F40 Competizione, a 1967 Mini Cooper S Rally, and a vintage Ford Bronco around a colorful Lego city, complete with destructible brick structures for you to smash into and a stunt park filled with jumps. You can even race the Lego cars against real-world cars or work to become a "Lego Speed Champion hero in a grand finale race on an epic Lego Goliath route."

The Forza Horizon 4 Lego Speed Champions expansion launches worldwide on June 13 on Xbox One and Windows 10 PCs for $19.99. Players who own the Forza Horizon 4 Ultimate Edition, the Forza Horizon 4 Expansions Bundle, or the Forza Horizon 4 Ultimate Add-Ons Bundle will gain access to the expansion at no additional cost. This isn't the first time a toy car-themed expansion has been released for Forza, either. Back in 2016, a Hot Wheels expansion was released for Forza Horizon 3, and it was one of the most creative expansion packs ever released for a racing game thanks to its insane tracks and unique cars.

In other Forza news, the Rimac C_Two has joined Forza Horizon 4's ever-expanding car roster, giving players a chance to take the electric supercar for a virtual test drive before it goes on sale next year. Making its racing game debut, the Rimac C_Two is likely to be the most powerful car in the game thanks with 1,914 horsepower and 1,696 lb-ft of torque enabling the electric supercar to sprint from 0-62 mph in just 1.85 seconds.
