STRAIGHT-SIX OR V12 | WHICH ONE SHOULD YOU BUY?
The Jaguar E-Type evolved considerably during its production life, but one of the biggest differences comes down to what sits under the bonnet.
Do you want the character of Jaguar’s legendary straight-six?
Or the effortless performance of the later V12?
Both deliver a very different E-Type experience, and choosing between them is less about which is objectively “better” and more about how you want the car to feel.
The straight-six: the traditional E-Type experience
For many enthusiasts, the straight-six is the engine most closely associated with the classic E-Type formula.
Whether 3.8 or 4.2 litres, it gives the car a more mechanical, involving character.
There is a sense of connection to the engine, gearbox and road that makes a well-sorted six-cylinder E-Type especially rewarding on a flowing country road.
It suits the car’s original sporting character beautifully.
That does not mean every straight-six E-Type feels the same, of course. Early Series 1 cars are generally the most coveted, while later Series 1 and Series 2 examples can offer much of the same character with a slightly different ownership proposition.
For buyers who value involvement, traditional sports-car feel and the classic E-Type silhouette, the straight-six is difficult to ignore.
The V12: effortless performance
The Series 3 introduced Jaguar’s 5.3-litre V12 and changed the character of the E-Type considerably.
The V12 is smoother, more relaxed and more muscular in the way it delivers its performance.
Where the straight-six encourages you to engage with the car, the V12 feels happier simply covering ground.
There is less need to work the engine, and at higher speeds the car takes on more of a grand touring character.
For owners who want to use their E-Type for longer journeys, touring or regular road use, that can be a significant advantage.
The Series 3 also has a broader stance and greater sense of maturity, making it feel quite different from the earlier cars.
It is less delicate, perhaps, but arguably more effortless.
Which is more enjoyable?
That depends entirely on what you consider enjoyable.
If your ideal E-Type drive involves quiet country roads, working through the gears and enjoying the mechanical feel of the car, the straight-six probably makes more sense.
If your idea of E-Type ownership involves longer journeys, effortless overtaking and the smooth delivery of a large-capacity engine, the V12 is difficult to beat.
Neither is the compromise.
They simply appeal to different drivers.
What about value?
The market generally favours the early straight-six cars, particularly Series 1 examples with strong provenance, originality and restoration history.
But that does not necessarily mean they offer the best value for every buyer.
A Series 3 V12 can often provide a great deal of E-Type for the money, particularly for someone more interested in driving than chasing the most collectible specification.
That distinction matters.
Buying purely on perceived desirability can leave you with the wrong E-Type for the way you actually intend to use it.
Drive both before you decide
Specifications only tell part of the story.
The difference between a straight-six and V12 E-Type becomes much clearer from behind the wheel.
One feels more traditional and involving.
The other feels smoother, stronger and more relaxed.
At DM Historics, we regularly offer E-Types across both ends of that spectrum, giving buyers the opportunity to compare the cars properly rather than making the decision from photographs alone.
If you are considering an E-Type, start by asking yourself one question:
Do you want involvement, or effortless performance?
That answer may tell you whether your E-Type should have six cylinders or twelve.
