Some corrections to an otherwise well researched video:
DAF is pronouced as a single word, not an abbreviation.
Renault and Volvo were in talks of a merger at the time and Volvo desperately needed front wheel drive technology, which is why the 400-series is basically a Renault 9 underneath. Volvo wasn't happy with the Renault's road holding so they had the rear axle redesigned by Lotus engineering.
Underpowered engines were due to Volvo Sweden's refusal to market fast cars at the time which would hamper their safety image. Volvo Netherlands sent the F3N engine to Porsche for developing a new cilinder head and turbocharged version. Porsche's engineers managed to churn out 170 bhp reliably with turbocharging, but Volvo Sweden wanted to protect their image and required the engine to be detuned to 120 bhp (we want a sporty car, not a sportscar). There are people who have reverse-engineered the ECU and tuned the engine back to 160-170 bhp.
Market introduction in the USA never materialised because American Volvodealers didn't want an expensive stylish small car that goes around corners, they wanted bricks or something that could compete with the Japanese in a straight line (the 480 was more expensive than a Datsun 280ZX). Volvo Sweden didn't want it because the 480's initial build quality was abysmal and they feared for their quality image. Fortunately for Volvo's marketing department, a currency crisis made the US Dollar very unfavourable in exchange rate, so the plan was quietly axed in 1988.
