but the Ford V4 was not far behind and was significantly easier to fit into the engine bay of the 96. The testing was done in secrecy. Per Gillbrand took a leave of absence and said he was going to run his father's paint shop. In reality he went to Desenzano in northern Italy with a 96 V4 prototype for testing. With five months to go before production only seven persons knew about the new engine. To maintain secrecy they rented a house west of Kristinehamn. To keep purchases of V4 specific parts secret they started the company Maskinverktyg AB. The ordinary purchase department at Saab was oblivious to what was going on, something that caused an incident when Rune Ahlberg cancelled the orders for cables for the two-stroke engine and the purchase department called the supplier and sharply told them to keep their deliveries. In the last week of July, just before the summer holidays, information about the new engine was released to further people and they were informed that full-scale production would start in four weeks. To keep secrecy, 40 of the ordinary staff were told to report to work to fix a problem with the disc brakes. Just prior to the official introduction, a journalist noticed a lorry loaded with 96s with V4 stickers on the front bumpers. The ordinary V4 engines produced between 1967 and 1976 had . Cars from the first year of production had engines with "Ford Motor Company" stampings. For the Swedish 1976 model year, the car - now known as the 96L - had its power reduced to 62 PS due to new Swedish emission regulations. However, the 1977-1980 models had , due to a two-stage Solex 32TDID carburetor. The V4 96 managed 0–100 km/h in 16 seconds. In August 1975 (called "1975B" in Sweden as the less powerful engine was kept for cars marketed after the beginning of the new year, when the new emissions standards took effect), the car received new impact absorbing bumpers similar to those on the 99 and an altered bottom plate which allowed the rear seat to be moved further back. In the US, the two-stroke engine was called the "Shrike" in 1967 and 1968. Its displacement was reduced slightly for 1968, to 795 cc, to avoid emission regulations which exempted engines under . The V4s used in US cars had a 1500 cc high compression
