I worked for a company in the early 80's snd they bought 2 identical VW vans. 1 was run in gently and driven with compassion whilst my one had abuse from day 1, I didn't know what mechanical sympathy was. These vans were kept for 7 years snd my one was always quicker,  could go uphill better and was generally a gruntier vehicle. 
IMHO as long as an engne has been warmed up before hand a good and proper caning is a good thing.
