I took delivery of a new L405 RR P400e recently after 3 yrs with a L494 RRS SDV8. The driving experience is a mixed bag so far for me compared to the SDV8. At slow speeds and assuming the car has charge remaining, it is a very serene relaxing drive because the car is mainly in EV mode and even when the charge is zero, the car still drives in hybrid mode (according to the EV display) most of the time and still delivers a very quiet drive. There are two things I don't like. The throttle response is slow from rest although once moving the electric motor provides reasonable shove and the brake pedal feel is inconsistent, I guess due to the regen When you want to accelerate faster, unless you are very light on the accelerator pedal, the petrol engine cuts in but providing you don't press the pedal too hard, the petrol engine remains relatively subdued. At constant motorway speeds, obviously the petrol engine is running nearly all the time but again it remains relatively quiet and doesnt detract from the drive The problem comes when the you want brisk acceleration and press the accelerator pedal more firmly. The petrol engine then has to rev hard, becomes quite raucous and it is at that point that you feel this is not how driving a RR should be. I think the L-R engineers have done a good job in terms of suppressing NVH from the engine but there's no hiding the fact that it is a 4 cyl lump. And then there is another issue. If you have battery charge left, the system goes into Boost mode in which the battery and petrol engine together deliver their full 400hp or so and the car actually accelerates satisfyingly briskly. However when there is no charge, there is only the puny petrol engine delivering any power and the acceleration is significantly slower. This can be a problem if you go for an overtake because you never quite know how much power youre going to get Having said this, the P400e is certainly delivering on economy. I installed fast chargers at home and work and most of my 22 mile commute is done in EV mode which means that I'm getting 100mpg+ sometimes on my commute (according to the L-R Remote app). In contrast on longer journeys I'm lucky to see 25mpg but overall so far I'm averaging about 44mpg which is considerably better than the average of 27mpg I achieved with the RRS SDV8 So am I regretting buying the P400e? The contract hire rate was significantly less than the D300 version (I guess because the residuals are higher), the VED rates are much lower and the fuel consumption is lower. Overall I'm saving my company about £3k a year so from that point of view I don't regret it. Do I miss the SDV8 engine? Yes, I sure do I think I agree that L-R have missed a trick not installing a 6 cyl petrol or diesel engine in the P400e. I test drove the Cayenne e-hybrid and that is a very engaging car to drive because of it's 3 litre petrol engine (shame about the pathetic 250mm wading depth though). I just hope that L-R come out with PHEV models in the future featuring 6 cyl engines because the 4 cyl engine doesnt really cut it in a RR PS Another thing that is driving me slightly nuts on the L405 is the lack of any space to conveniently store sunglasses. The old L322 had that excellent sunglasses holder above the mirror. Shame on L-R for not carrying that over to the L405. Anyone got any solution for this? |

I agree with your impressions and also I, too, was missing the sunglasses holder from the L322, so I replaced the driver's useless handle with this:

I just hook them into the little plastic loop on the top left of the sun visor. Seems quite convenient... There is nothing that can't be fixed with a hammer😜😜

Yes thanks; the dealer was well up to a JLR stealership, couldn’t care less.... Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits.

And that is the exact same position the Outlander left me in, albeit not as luxury vehicle, it also felt underpowered when no electric was left, which in the winter was always out after about 18 miles not the 28/30 it would suggest!! lol I just dont get why Porsche can do it but JLR cant!! The 2.0 is just too noisey when no electric is done! And certainly isnt going to deliver the 400hp and 0-60 figures it claims surely!! all smug in my new plug! 2021 Westminster Black D300 2013 Vogue SE - gone Some Porsche Cayenne guff pretending to be a 4x4!! 2006 Vogue 2004 Vogue 2001 Vogue |

You're welcome, be sure to select the correct holder colour, in my case it was ivory... |

Mods. This needed to be said again ..... I’m not sure but wasn’t it an eu regulation that demanded that car producers balanced their portfolio of lumpy proper cars like a FFRR with a fairy car ...so on average they hit a reasonably low level of output basically knackering the big car producers such as JLR So.... for good or bad as we are out if the eu, can we have a sensible Diesel engine back again? DONT FORGET WHAT IT SAYS IN THE SIGNATURE BELOW....

It's progress? I don't want to lecture, but I do want to remind not to focus on the spec: cylinders or capacity. Focus on the outcomes: power, torque and, crucially, the driving characteristics in the real world.

I worked in USA a couple of years ago for 10 months or so, I was given a 5 litre V8 Mustang as my hire car. Whilst there it had to have a service, they gave me a 2.3 eco boost Mustang. The 2.3 was quick, really quick but it had to rev and it's exhaust note was not in keeping with the car, number of cylinders does count considerably in my book, a 4 pot in a Rangie simply isnt right.

I totally agree with you (but only in the context that trains should be steam trains and recorded music should be on vinyl. Those were the days!)
