The LEGO® Group has had system based powered-up hubs and motors for a while, but it appears they are now selling a technic oriented version. The hub is 89.99 USD, while then L and XL motors are 39.99 USD. Product reviewer Mike 3 notes buying a hub and two motors individually is a HORRIBLE idea, because the Top Gear Rally car includes the hub, and one L and XL motor with 460 extra parts for 40 bucks less. It’s no wonder its sold out on Shop.LEGO.com, but Amazon had them in stock last time I checked.
