Ahmed Yousef, 29, was left with life-changing injuries after Haider Mirza, 21, sent him flying 65ft into the air during the collision in Derby in November 2017.
Mr Yousef still needed intensive physiotherapy more than a year after the smash.
Mirza was sentenced to 40 months youth custody at Derby Crown Court on Friday and is banned from driving for 44 months, DerbyshireLive reports.
In horrifying CCTV footage Mirza smashes into the victim, flips him over the bonnet and high into the air.
Ahmed spins horribly as he flies over the racing car before he crashes on to the road and slides on to the pavement.
Panicked witnesses sprint to the unconscious young man as he lies seriously injured, and Mirza speeds off.
Mr Yousef suffered fractures to his shoulder, injuries to his side and he broke his right knee.
In December 2018 Mirza pleaded guilty to causing serious injury by dangerous driving, driving without a licence, failing to stop after a collision and using a vehicle with no insurance.
Prosecutor Lynn Bickley said at the earlier hearing: "It is a serious offence. Mr Yousef was crossing the road when he was hit by an Audi A3 at speed.
At the same hearing, Mirza's defence Asif Munir said: "Mr Mirza has taken a decision which will impact on the next few years of his life.
