 Which of these is the odd car out?
Answer: Each of these cars was sold in one market only with an altered engine capacity. The Audi is the odd one out, as its capacity was 22cc larger, the other three had displacements reduced to suit local rules.
Audi 100LS: For the Swiss market, the 100 LS was equipped with a version of the M118 OHV engine bored out by 0.5 mm to increase its capacity from 1760cc to 1782cc. This placed the engine above the 9 fiscal horsepower tax threshold in the nineteen cantons where this system was applied. I have not been able to find an explanation as to why this was considered desirable – the Swiss do not seem any keener to pay tax than the rest of us.
Daihatsu Charade: From the 1980 model year, Charades exported to Chile were supplied with an 843cc version of the C-series triple in order to fit into a lower taxation category for imported cars. The capacity reduction was achieved by a smaller cylinder bore, reduced to 70mm from the 76mm 993cc engines.
VW Polo Typ 86: For the Swedish market only, VW offered a smaller capacity EA111 engine from 1976-77, with a 771cc displacement, achieved by a 4.5mm reduction in cylinder bore relative to the next-smallest 895cc engine. The reason for the reduction was to bring the engine under the 0.8 litre threshold for Sweden’s 1976 emissions regulations.
Fiat 850: At the time of their introduction into the United States the 850 Sedan, Coupé and Spider were marketed with a reduced capacity 817 cc (50 cu in) engine in order to slip below the US emissions regulations threshold, by which engines equal to or smaller than 50 cubic inches were exempted from the need to comply.
 BMW is said to have considered giving the original E12 generation 5 Series a name as a suffix to its model number designation but dropped the idea. What was the name and why was it dropped?
Answer: The suffix was to be ‘Olympic’ in commemoration of the 1972 Munich Olympic Games. The plan was dropped after the attack on the Israeli team by the Black September terrorist group that resulted in twelve deaths.
 Why did the Russian state limousine manufacturer change its name from ZIS to ZIL in 1956?
Answer: The ‘S’ in ZIS stood for Stalin and President Khrushchev had denounced the cult of personality surrounding the former Soviet leader. The new name ‘Zavod imeni Likhachyova’, was a tribute to the factory’s former director Ivan Alekseevich Likhachov (1896-1956).
 When BMC appeared uncommitted to continuing production of the Vanden Plas Princess 4 Litre R, Rolls-Royce offered its FB60 engine to which other British car manufacturer?
Answer: Rootes Group. This appears to have happened at the time of the announcement of the merger of BMC and the Jaguar group of companies in July 1965. Rolls-Royce, on their own initiative, bought a Humber Super Snipe and fitted it with an FB60 engine for demonstration to Rootes. The venture was doomed to failure as Rootes had already tried Ford and Chrysler V8 engines in the big Humbers, and were to cease production of the range in mid-1967 as Chrysler took full control of the business.
According to the memoirs of Peter Hill, a Rolls-Royce engineer involved in the project, the re-engined Humber was a far nicer car than the Princess 4 Litre R, superior in ride, refinement, and handling.

 Why was the frontal appearance of the Wartburg 353 changed from the prototype design below at a late stage of the car’s development?
Answer: When the round headlamped 353 prototype was presented to Walter Ulbricht, the DDR’s Chairman of the State Council (effectively head of state), he declared that “Our cars should not look like Jeeps”.
To placate the squeaky-voiced, Lenin-bearded former carpenter, Automobilwerk Eisenach’s in-house stylist Hans Fleischer duly revised the frontal treatment, dusting off an arrangement of rectangular lamps and a horizontally barred grille proposed for the previously abandoned P100 ‘Paloma’ saloon and reworking it into a more production-friendly form.
 What caused GM’s first electric car, the EV1, to become a public relations disaster for the company?
