Twenty-two-year-old Paul Stewart, who was driving a powerful two litre sports Renault Clio, overtook on a blind bend on the Prestwick to Strathaven road near to Auchincruive Agricultural College on February 11, last year.
Stewart, of Mossblown, Ayr, managed to get the car back in to avoid a collision with a bus, but his car then spun out of control and hit a works van driven by 52-year-old Robert McPike which was travelling behind the bus.
The force of the impact forced Mr McPike's van into a field. He was unconscious at the scene and later died from his injuries.
At the High Court in Glasgow judge Norman Ritchie QC told Stewart, who at only been driving for two years when the fatal crash occurred: "You were driving a ludicrously powerful motor car.
"Your driving was bad, it was dangerous and you persisted in that bad driving. Your age, the type of car and manner of driving made something of the stereotype of the boy racer."
Judge Ritchie also banned Stewart from driving for 10 years.
Mr McPike, a self-employed joiner who was married with four children, was on his way to price a job for a customer when his works van was smashed into by Stewart.
The court heard that Stewart, who was trapped in his car, was screaming "I'm dying, I'm dying.
Eyewitness Lisanne Graham, a company director, who was driving in front of Stewart's car said she was intimidated by the way he was driving so close to her.
She added: "He shouldn't have taken the corner like that."
Advocate depute Bill McVicar, prosecuting, in his closing speech to the jury, said: "It was folly to take the blind corner on the wrong side and it amounts to dangerous driving."
Stewart denied causing death by dangerous driving, but was found guilty after trial.
He did not give evidence, but his defence counsel Gavin Anderson, told the jury that the sporty Clio, which his client had bought four days earlier had had faulty brakes and a shock absorber and this may have contributed to the accident.
The court heard that Stewart, who worked at a recycling plant, was badly injured in the crash and had to undergo an operation on his leg.
Mr Anderson said that Stewart lost his job at the recycling plant which involved manual labour, as a result of the injuries he received in the crash.
Mr Anderson said: "Mr Stewart is devastated by the fact he is responsible for the death of another person. He is struggling to cope with events and has been having counselling."
