I believe the D250 (249HP) and D300 (300HP) use the same inline six-cylinder Ingenium diesel engine, perhaps they're tuned differently? MY2021 Defender 90 P400 SE

The 3.0L is available in 3 versions on Defender - 200BHP - 250 BHP and 300 BHP - there is also a 350BHP 3.0i6 on the RR I believe?
You get more torque compared to the 4 cylinder for the same BHP from the 6 V 4 cylinder |

I still can't really work out the difference between a 3.0L and a 2.0L if they both have the same power output.
I'm guessing torque... |

D250 - 570nm for the 3.0 and 500nm for the 2.0 (D240)
D200 - 500nm for the 3.0 and 430 for the 2.0. 24MY 90 D250 HSE, Tasman Blue Last edited by J77 on 4th Jan 2021 4:31pm. Edited 1 time in total |

One is a four-cylinder and one a six-cylinder - the latter has a bunch more torque as above. Plus in theory less stress on components for a given power output.
Not to mention the silky-smooth nature of six-pot compared to a four? |

"New Ingenium in-line six-cylinder diesel engine and Intelligent All-Wheel Drive A new in-line six-cylinder diesel option from the Ingenium engine family is now available, offering enhanced torque delivery, smooth responses and improved fuel economy thanks to its Mild-Hybrid Electric Vehicle (MHEV) technology and a new Intelligent All Wheel Drive system. Sitting at the top of the range, the D300 delivers enhanced power and torque, with 300PS and 650Nm of torque, providing a 0-60mph time of 6.3 seconds (0-100km/h in 6.7 seconds) for the Defender 90. The higher torque figure means the Defender D300 provides effortless performance both on and off-road, perfectly fitting Defender’s tough character. The MHEV technology contributes to enhanced fuel economy through an efficient Stop/Start system which cuts the engine at a standstill, as well as recuperating energy normally lost under braking or decelerating. This energy is then sent back into the battery pack and can be redeployed later. A key benefit of MHEV is that this energy is used when accelerating, delivering faster responses for greater performance. The new intelligent driveline system continually varies axle torque based on sensor data from the vehicle’s surroundings and driver inputs to distribute all torque to one axle or the other as required. This intelligent torque distribution system optimises the driveline for traction, on-road dynamics and driveline efficiency, resulting in improved fuel economy and reduced CO2 emissions – all without sacrificing any of Defender's inherent off-road capability. In combination with MHEV technology and the superior refinement of the in-line six-cylinder engine, the diesel Defenders are more economical, more responsive and more refined than the engines they supercede. The D200 and D240 become D200 and D250 models for 2021, using the same in-line six-cylinder Ingenium engine as the D300 with 200PS and 249PS respectively. An uplift in torque delivers enhanced usability, with 500Nm (D200) and 570Nm (D250) available, utilising MHEV technology to boost fuel efficiency and reduce emissions across the diesel Defender line-up". |

I can't see anywhere in that press release an explanation about the differences between a 2L and 3L engine each with the same horsepower.
Unless I'm missing something. |

But that's cylinders (which I know make up the total displacement). |

For the same POWER (BHP) you get more TORQUE (NM)

70Nm more peak torque with a broader and greater level of torque off-boost, so it will have better part-throttle response. Simply, larger capacity engines are less reliant on boost from the turbo to make torque so they are more linear.
A straight-six engine also has practically perfect balance for lower levels of vibration. There's lot more to it than an extra 10bhp.

Are the 3.0 diesels available now ? And are the 2.0 diesels now redundant?

Yes, available to order now and dealers will have some 3.0 stock.
The 2.0 diesels aren’t redundant, just superseded. There will be some new ones around so could be worth a deal if you are okay with the smaller engine. But personally having driven both I’d go with the 6-cylinder. |

I have a d240 and a range of other new JLR engines v and straight. Noting the past sizes of defender engines and the uses of 2l in the range, power output - I don’t think it’s a big deal. They will always up-play the new engine - don’t blame them, but I don’t think it’s a huge benefit for such a small improvement etc Mike |

Or less revs. |
