The 2027 Land Rover Defender OCTA: Power Down Of Almost 100 Hp but why.
The 2027 Defender OCTA is one of the most powerful Defenders ever built, but if you're buying one in Europe, it's going to be less powerful than the first examples by almost 100 hp. Land Rover engineers have downsized the V8 engine's power output to stay within the emissions regulations. Let's explore what's different, the reason for the update, and how it might affect your decision to buy the Defender OCTA.

What Changed
The Defender OCTA uses a twin-turbocharged 4,4-liter V8 engine from BMW, which makes 626 hp. However, the same engine produces 533 hp in Euro spec vehicles. That's right, almost 100 hp less than in US spec cars.
Although the power output dropped, some aspects of the performance remain the same:
Same 750 Nm (553 lb-ft) of torque, so the OCTA will accelerate just as strongly
0-62 mph time is slower by 0,4 seconds, now at 4,4 seconds
The exhaust system gets a new tuning to give the V8 a deeper and more intimidating
sound
Other aspects of performance remain the same, including the towing capacity, ground clearance, approach, and breakover angles. The changes only concern the powertrain's output and, accordingly, the performance
figures.
However, only the cars sold in Europe get the downgrade. If you buy the Defender OCTA elsewhere, you can expect 626 hp.
Reasons For The Downgrade
The most evident reason for the downgrade is the change in emissions regulations. Euro 6e-bis regulations apply to the EU, and the only way to make the V8 pass the new tests is to reduce the power output by altering the engine's software. Other manufacturers had to make similar updates to their engines. Recently, the BMW M5 received a similar update, which lowered its power output by 41 hp. However, the M5 is a plug-in hybrid, and the additional electric motor allowed BMW to make up for the loss.
However, the Land Rover Defender OCTA is not a hybrid. There is no additional electric motor that could make up for the lost power when the engine is put under strain. Therefore, reducing the power output by nearly 100 hp took a much more significant toll on the performance figures.
Will The V8 Disappear From The Rover
Portfolio
For now, no. The same engine powers the Range Rover and Range Rover Sport, and it is already prepared for the upcoming Euro 7 standards, so it's safe to assume that Land Rover will continue to use it for the next decade or so. BMW also plans to use the S68 engine in the X5, 7 Series, and the next X7. Therefore, it is safe to assume that the V8 will continue to be produced for the next
several years.
Land Rover is not the only company that wants to continue using large-displacement engines. Other manufacturers, such as Porsche, Mercedes, and Rolls-Royce, also plan to continue using their V8, V12, and even V16 engines for as long as possible. However, there is a limit to how long air-cooled powerplants can remain relevant, and emissions regulations are slowly pushing manufacturers to electrify their powertrains. In particular, the European Union has mandated that automakers reduce their fleet's emissions by 90% from 2021 levels by 2035. To comply with the stricter standards, manufacturers will have to fundamentally change their powertrains or offer more EVs and hybrids to balance out the sales of their large-displacement
combustion vehicles.
Your Next Defender OCTA: What To Know
If you are buying the Defender OCTA in Europe, you can expect the power output to be reduced by nearly 100 hp. Otherwise, the performance figures remain the same, so the 0-62 mph time of 4,4 seconds, and the 750 Nm of torque will remain the same. If you are outside the EU, it is possible to buy the 626 hp version of the Defender OCTA, so it's worth contacting your local dealer to confirm the powertrain specifications
before buying.
Overall, the Defender OCTA remains one of the most powerful SUVs on the market, with the power output only affecting the performance figures in theory. Unless raw power is your priority, the differences are unlikely to affect your choice. However, if you want to know exactly which engine you are buying, it's crucial to ask the dealer about it since the specifications can differ significantly depending on where you buy the vehicle.
