The Jensen 541R is a closed four-seater GT-class car built in the United Kingdom by Jensen between 1957 and 1960. The original aluminium prototype appeared in 1953 as the 541 at the London Motor Show, although this changed to glassfibre for all production cars. Within a year, the new 541 had already earned rave reviews from magazines, notably Autocar, whose testers drove the grand tourer to a top speed of over 125 mph (201 km/h). It was the fastest four-seater the magazine had ever tested at the time.
