The Jaguar XJ-S (later the XJS) was introduced in 1975 at the Frankfurt Motor Show, ushering in a new generation of GT motoring for the company, successfully combining performance, luxury, and elegant styling. A testament to both the inherent quality of the design and its popularity, the XJ-S remained in production for the better part of two decades. Power came from the 60-degree all-alloy V-12 engine first used in the 'Series 3' E-Type and made use of the Jaguar XJ6/JX12 saloon platform and running gear. Its wheelbase was shorter than its saloon siblings which complemented the lively V12 engine. The XJ-S's engine used a single overhead camshaft per bank, fuel injection, and produced 285 horsepower from 5.3-liters. At the time, it was one of the first production cars capable of achieving the magical 150 mph.
