The AC 289 is a sports car produced by the British manufacturer AC Cars between 1963 and 1965. It is known for being the first car to use a Ford 4.7-liter V8 engine, which gave it impressive performance for its time.

The AC 289 was based on the AC Ace, a lightweight British sports car. The Ace had previously used a Bristol straight-six engine, but with the arrival of the Ford V8, AC Cars saw an opportunity to increase the performance of the car.

The 4.7-liter V8 produced 271 horsepower and 312 lb-ft of torque, which was a significant improvement over the Bristol engine. With this engine, the AC 289 could reach a top speed of 152 mph and accelerate from 0 to 60 mph in just 5.8 seconds.

The AC 289 was available as both a roadster and a coupe, with a total of around 200 units produced. The car was popular with racing drivers and enthusiasts, and was used in a number of competitions, including the 24 Hours of Le Mans.

Today, the AC 289 is a sought-after collector’s car, with prices ranging from hundreds of thousands to millions of dollars depending on condition and rarity. It remains a testament to the successful partnership between AC Cars and Ford, and the innovative use of American V8 engines in European sports cars.
