For 1959, the Facel Vega HK500 was introduced. Essentially, it was just a renamed, upgraded FVS. Equipped at first with the 335 hp 5.8-litre V8 from the FVS, the HK500 soon received a 360 bhp 6.3 litre Chrysler V8 making for a top speed of 147 mph (237 km/h). 60 miles per hour came up in 8.5 seconds. Initially disc brakes were optional, becoming standard in April 1960.
