Jensen FF (1966-71)

The Jensen FF and Jensen Interceptor are iconic classic cars, but like any vintage vehicle, they have their share of common issues. Let’s explore some of the typical faults associated with these models:
1. Engine and Exhaust:
o Worn V8 Engine: Rumbling on start-up can indicate a worn V8 engine. Pay attention to an oily engine and a smoky exhaust once warm. If the exhaust is smoky and uneven, it could be a burnt valve.
o Exhaust Manifold/Head Joint Leaks: Leaking exhaust manifold or head joints can be cured with copper gaskets.
o Overheating: Overheating is a common cause of engine problems. Check for signs of boiling or leaks. Issues may stem from a silted-up radiator or failing electric fans.
2. Body Panels and Build Quality:
o Handbuilt Body Panels: The Jensen cars were handbuilt, and repairing body panels can be time-consuming and expensive. Even simple changes, such as replacing bonnets, can cost around £1000.
o Originality vs. Usability: Decide whether you want an original example or one that has been upgraded. While the Interceptor is receptive to engine, suspension, and brake upgrades, an original example is a safer investment.
o Patchy Factory Build Quality: Factory build quality was inconsistent, so finding an original example can be challenging. Most surviving cars have likely undergone rebuilding.
3. Electrical and Accessories:
o Electrical Devices: Check that all lights are working and have equal power. Test electrical devices in the cabin.
o Air Conditioning: Air conditioning rarely works in these classics. Consider a modern upgrade if needed.
4. Special Versions:
o Consider special versions like the four-wheel-drive FF or the convertible for a unique ownership experience.
Remember, when buying a Jensen Interceptor or FF, prioritize the body condition and choose wisely between originality and usability.

Generations
The **Jensen FF** had a **single generation**, produced by British car manufacturer Jensen Motors between **1966 and 1971**. It was a groundbreaking vehicle, being the **first non all-terrain production car equipped with four-wheel drive** and an **anti-lock braking system**. The powertrain was sourced from Chrysler, featuring a second-generation **6.3-liter V8 engine** and a **3-speed TorqueFlite A727 automatic transmission**. The FF's name stands for **Ferguson Formula**, named after Ferguson Research Ltd., the company that invented its four-wheel drive system. Although highly innovative, the FF faced commercial challenges due to its high price and design issues related to left-hand drive. Approximately **320 to 330 examples** of the Jensen FF V8 model were made by Jensen Motors Limited in the UK. Notably, the FF's four-wheel drive system predated the successful AMC Eagle by thirteen years, the Audi Quattro by fourteen years, and the Subaru Leone by five years. Despite its technical achievements, the FF could not be sold in the United States due to its right-hand drive setup. The FF is related to the similar-looking, rear-wheel-drive **Jensen Interceptor**, but it is longer and mechanically distinct.
*****
The **Jensen FF** shared its engine and gearbox with the more famous **Jensen Interceptor**. Specifically, it utilized a **325 bhp 6.3-liter Chrysler V8 engine** paired with a **three-speed TorqueFlite A727 automatic transmission**. These components provided the FF with ample power and smooth performance, making it a grand tourer that combined luxury with innovative four-wheel drive technology.

2. **MK II (1969-1971)**: This version saw 110 units produced. It featured an interior designed by William Towns, which many consider the best of the series. Most MK II models were equipped with air conditioning².

3. **MK III (1971)**: The rarest of the FFs, with only 15 units produced. These models included many last-of-the-line changes, such as a revamped interior, new alloy wheels, and ventilated discs².

Racing
The Jensen FF, despite its advanced technology for the time, was not designed or widely used for racing. Its primary focus was on being a high-performance grand tourer with innovative features like four-wheel drive and anti-lock brakes. The car's weight and luxury-oriented design made it less suitable for competitive racing environments.

However, the Ferguson Formula four-wheel-drive system used in the Jensen FF was tested and proven in various racing applications, including Formula One. This technology demonstrated its potential in motorsport, even if the Jensen FF itself did not directly compete.
