The main change was the engine; the 4/44 used a pre BMC Morris XPA unit and after the MG TF stopped production it was the only car still fitted with it. To rationalise production the 15/50 was launched with the BMC B-series engine fitted. Much of the design was shared with the MG Magnette, although some of the panels of the MG Magnette ZA/ZB (e.g. the boot and rear wings) are not interchangeable with those of the Wolseley 15/50, as stated in Practical Classics. Unlike the MG, the 15/50 engine had only a single SU carburettor so the power output was slightly less at {{convert|55|bhp|abbr=on}} at 4400 rpm.[2] Unlike the 4/44, the 15/50 had a floor gear change. From 1956 a "Manumatic" two pedal (centrifugal clutch) transmission was an option. This was controlled by a micro switch hidden in the gear lever operating a vacuum servo. Having no synchromesh on bottom gear could make changes into the lowest ratio, which would normally require double declutching, difficult.[2] The construction was monocoque with independent suspension at the front by coil springs and a live rear axle with semi elliptic leaf springs. The steering was rack and pinion and Lockheed brakes were fitted with {{convert|9|in|mm|abbr=on}} drums all round[2] In keeping with the up-market positioning of the Wolseley brand the car had upmarket trim with polished walnut dashboard and door cappings and leather seats and a traditional Wolseley radiator grille with illuminated badge. The individual front seats were placed very closely together to allow the car to be used as a six seater albeit marginal but it was usually sold as a four seater. The handbrake lever was under the dash. A heater was fitted as standard. PerformanceAn example with Manumatic transmission tested by the British The Motor magazine in 1957 had a top speed of {{convert|77.9|mph|km/h|abbr=on}} and could accelerate from 0-{{convert|60|mph|km/h|abbr=on}} in 26.7 seconds. A fuel consumption of {{convert|28.7|mpgimp|L/100 km mpgus}} was recorded. The test car cost £1011 including taxes of £338.[2] It was replaced in 1958 by the Farina styled Wolseley 15/60.
