StarLight Garage presents the Jensen Interceptor III Convertible from 1975. We had already a Jensen car in GT5 but it deserves to come back don't you agree?
And I like this convertible version so bring it in PD!

The Jensen Interceptor is a great example of what happens when you get the Italians, Brits and Americans in a room in the late-60s to collaborate on a multi-national muscle car. Design was tasked to the Italians by way of Carrozzeria Touring, construction took place at the Jensen factory in Birmingham and the engine/transmission were supplied by the Americans.

Originally introduced in 1966, the Interceptor was a hand-built sports GT car with a price tag approximately 60% higher than that of the Jaguar E-Type. The relatively high cost and limitations of the handmade coach work meant that the Jensen Interceptor was never a huge seller – over the course of its 10 year production run just over 6,400 were produced, almost all of which were the classic hatchback, with 267 convertibles and just 60 coupes rounding out the numbers.

Perhaps the most famous feature of the Interceptor is the obscenely large V8 that sits under the hood, the smallest variant was a 383 cubic inch (6.3 litre) Chrysler V8, and the larger was the 440 cubic inch (7.2 litre) Chrysler unit.

However this car on the picture seems to have be a 4-barrel and produces only 280 horsepower.

Of course, the great benefit of fitting fire-breathing American V8s to your sports car is that maintenance costs drop through the floor, reliability is excellent and your car sounds like Barry White’s pet Cthulu on a meth binge.

The Interceptor was originally produced in three distinct generations, the third generation benefited from lessons learnt from the first two, and it was also the only generation to be offered as a convertible. Jensen had decided to produce the droptop to further their appeal in the American market, but it also sold them with some success in Europe.

The most powerful engine ever used in a Jensen was the 440 cubic inch OHC V8 with the triple two-barrel carburettor option capable of 385hp at the rear wheels.

The 440 Six Pack was long gone by the time Jensen got around to making convertibles. It would have probably been fine to sell in Europe with their much looser emissions restrictions, but Chrysler simply stopped making the engine entirely. Pretty sure the one in the OP is a 4 barrel.

Hi @StarLight I voted like because the Interceptor Convertible is a great car and as far as I'm concerned you can't have too many high performance convertibles in the game.

However, I was pretty sure that the triple carb engine was not fitted in the convertible so I checked via richardcalver.com (Richard is the expert on Jensens) he states that Jensen used up their supply of Six Pack engines in 1973. The convertible didn't go on sale until 1974.

http://www.richardcalver.com/article_convertible.htm

The Six Pack bonnet had louvres cut in the full length of the bonnet (presumably as this engine generated more heat) - the car in your photos doesn't have a Six Pack bonnet. A louvered bonnet was an option on the MK3, but the louvres only cover half the length.

The air filter on the Jensen Six Pack was elongated and held on by two bolts and was open around the periphery exposing the edge of the filter medium. The engine in the photo as @Tornado says above appears to be a four barrel.

It would probably be best to change the OP to give details of the engine available in the Convertible which gave 280bhp with a four barrel carb.

Some people may have retro-fitted Six Pack engines into Jensens, but SP's were often returned to Jensen or the dealer to be fitted with four barrel carbs. When fitted in the congested engine bay of the Interceptor they had a tendency to overheat and be unreliable as well as being difficult to drive - the central carb which was connected to the throttle was a 300cfm unit, but the other two carbs were 500cfm and operated when the vacuum rose above a certain level - this could result in them cutting in when the throttle was released or when going uphill.

Hi Sick Cylinder I understand your comment but the information is retrieved from an auction site, Bonhams not just a site. So I just took over the specifications which I thought would match with the story about the car.
The specifications are there mentioned as is .... your do you believe the buyer has got the wrong engine?
So you are saying the engine on the picture is a 4-barrel carburetor.
Anyway I will correct the engine specifications to avoid confusion.

Many thanks for your comment and have a nice day.
:cheers:

Thanks Starlight. It is unusual for an auction site to make mistakes, especially Bonhams, but they also say that 265 convertibles were sold, Wikipedia states 267, but the actual figure is 509 according to Richard Calver.

The bhp figures were measured at the flywheel not at the rear wheels.

The 280 figure was also a net rating of a four barrel 440, whereas the 385 was a gross one of the Six Pack (actual was 330 net, as installed in equivalent 1971 Chryslers).

Due to creative writing liberties; you Sir may be in the running to surplant Neil Gaiman as my favorite author.

No, this one is not written by me ... although I have threads which are written by myself. :embarrassed:
I'm not the level of the Sandman writer. :D

Have a nice day.

I like both cars ... so doesn't matter which one will return ... prefer both but the old one (in GT5) is also fine for me.
:cheers:
I like all three body styles (Hatchback-coupe, Coupe and convertible) but I do prefer the Hatchback for some reason, but this convertible is not bad at all, much nice:D
