In 1967 Aston Martin debuted the DBS with its wider and longer body designed by William Towns. The DBS was designed to use the new four-cam V-8 the company was developing. However, the new engine was not ready as production was ready to start so the proven 6-cylinder engine from the DB6 was used.
In standard tune with a 8.9:1 compression ratio the 6-cylinder engine was rated at 282bhp. With the Vantage tune (no extra cost) with a 9.4:1 compression ratio and a faster cam the rating increased to 325bhp.
The most noticable design change from the DB6 was a new front with four quartz iodine headlights located in the grille.
In Januray 1970, concurrent with the introduction of the DBSV8, a few cosmetic changes in the DBS were made resulting in a series II DBS. The earlier DBS has louvers in the "C" post behind the read side window and the panel beneath the main rear window had no louvers. This was reversed on the series II cars which has smooth "C" posts and louvers in the panel beneath the rear window.
The DBS was in production from 1967 through April 1972. A total of 787 (some say 860) cars were built.
The new Aston Martin V-8 engine was finally ready and production began on the DB6V8 near the end of 1969. The new twin-cam engine produced 375 bhp in its standard-tune form. The new DBSV8, which weighed nearly two tons, could acheive top a top speed of 160 mph which was unbelievable for a 4-passenger vehicle of that era.
The car was made in only the saloon body style and can distinguished from the DBS 6-cylinder car by the cast aluminum wheels on the V-8 as opposed to the wire wheels on the DBS 6. Most of the cars made had an automatic transmission.
The DBSV8 was in production from 1969 through 1972. A total of 405 cars were built.
