“76921 Audi S1 e-tron quattro really caught my attention when the new Speed Champions sets were revealed, thanks to my appreciation for rally cars and the model's stunning livery. Having now built the set, however, I think its greatest strengths are the realistic shaping and... More the clever construction methods needed to create these shapes.”

The Brothers Brick
“76921 Audi S1 e-tron Quattro still earns a recommendation from us, particularly if you want to add something a bit different to your LEGO garage. The S1 e-tron Quattro, as it’s called, was built by Audi at the behest of the late Ken Block for his Gymkhana series. That goes... More some way to explaining why it looks so bonkers! Its madness is very well recreated in the brick.”
