The Riley One-Point-Five and similar Wolseley 1500 are cars produced by Riley and Wolseley respectively from 1957 until 1965. They utilised the Morris Minor floorpan, suspension and steering but were fitted with the larger 1,489 cc (90.9 cu in) B-Series engine and MG Magnette gearbox.
The two models were differentiated by nearly 20 hp (15 kW), the Riley having twin SU carburettors giving it the more power at 68 hp (50 kW). The Wolseley was released in April 1957 and the Riley was launched in November, directly after the 1957 London Motor Show.[5][6]
The Series II was released in May 1960. The most notable external difference was the hidden boot and bonnet hinges. Interior storage was improved with the fitting of a full width parcel shelf directly beneath the fascia.[6]
The Series III was introduced in October 1961, featuring revisions to the grille and front and rear lights.
In October 1962 the cars received the more robust crank, bearing and other details of the larger 1,622 cc unit now being fitted in the Austin Cambridge and its "Farina" styled clones. Unlike the Farina models, however, the Wolseley 1500 and Riley One-Point-Five retained the 1,489cc engine size with which they had been launched back in 1957.[6]
Production ended in 1965 with 19,568 Rileys and 103,394 Wolseleys made.[7]
The One-Point-Five and its 1500 sibling had a number of differences, with the Wolseley generally being the less well-equipped model:
A Wolseley 1500 was tested by the British magazine The Motor in 1957. It was found to have a top speed of 76.7 mph (123.4 km/h) and could accelerate from 0-60 mph (97 km/h) in 24.8 seconds. A fuel consumption of 36.6 miles per imperial gallon (7.7 L/100 km; 30.5 mpg‑US) was recorded. The test car cost £758 including taxes of £253.[4]
A Riley One-Point-Five was tested by the British magazine The Motor in 1961. It was found to have a top speed of 82.4 mph (132.6 km/h) and could accelerate from 0-60 mph (97 km/h) in 18.9 seconds. A fuel consumption of 29.8 miles per imperial gallon (9.5 L/100 km; 24.8 mpg‑US) was recorded. The test car cost £815 including taxes of £240.[8]
In its day, the Riley was successfully raced and rallied and can still be seen today in historical sporting events.
BMC Australia produced the Wolseley 1500 in Australia from 1958.[9] It was built alongside BMC Australia's own versions of this design, the Morris Major and Austin Lancer.[9] The Major and Lancer were less luxurious and had many notable differences from the Wolseley.[9] The 1500 was discontinued in 1959 and substantially revised "Series 2" models of the Major and Lancer were released in the same year.[9] In 1962 the Lancer and Major were replaced by the Morris Major Elite which was powered by a 1,622 cc (99.0 cu in) engine.[9]
1959 Series I Riley One-Point-Fives were exported to North America by BMC in an attempt to capitalize on the growing imported car market. While not a sales success, a number of the cars remain on the road in the hands of collectors. As was a common practice in many jurisdictions, some cars were titled as 1960 model year cars because that was the year of their initial registration.
The badging for the One-Point-Five was changed early on in Series I production, after car number 4861 and before 6353. The earlier cars have smaller badges on the front wings and the boot lid. The later cars use simpler, larger badges with a different design and typeface.
