It appears that LR is reducing the HP in the V8 . They originally stated power of 525 and 518 HP, now i see that both models are reduced to 518 and 493 respectively. Acceleration has remained the same.

Does anyone know what is going on? I just ordered a P525 and wonder if it will now be a P518???

 

Did the Defender V8's come with the Ford V8? I wonder if JLR is switching the Defender V8 to the BMW V8.

 

The V8 has 525 metric horsepower which translates into 518 US/English horsepower. Nothing has changed.

Also the V8 is a Jaguar engine not a Ford.

 

I thought it was a Ford design as well - turns out it is an old GM design from the 1950's:

No. This is the Rover V8 that was in Range Rovers and Defenders until the 1990s. The AJV8 was a new in house design that was done during Ford ownership.

Better question is why we don't have the 592hp version in the Defender V8.

 

The AJV8 design is based off the Rover V8, JLR made it in house like you said, but it's still based off an old GM design. They were under Ford ownership when they made the AJV8 but Ford had nothing to do with the actual design.

 

No it's not. Read up.

 

It’s based on the Buick 3500 aluminum V8 in the sense that it has 8 cylinders in a V-formation. Beyond that, nope.

 

It has nothing to do with the GM engine. Jaguar literally did a single cylinder study for use in 4,6,8 and 12 cylinder configurations. As I said do a little reading below.

"During the BL days there had been some discussion of using the Buick-derived Rover V8, which had substantial advantages in terms of weight (in fact it weighed half as much as the V12), cost and size. Unfortunately, most of the advantage came from the fact that it was relatively thin walled and so suffered in refinement a little. But in reality this could have been developed out, as was the case in the final fling of the Rover V8 inside the P38a Range Rovers.

However, that venerable V8 was itself a relic of the 1960s and ultimately suffered from the same issues as the old Jaguar engines, in terms of efficiency and emissions. It also struggled to meet the power demands of modern cars, the 4.6-litre version only putting out 220bhp."
