If any car in the world will get a retrofit it would be the defender. Actually the defender may make a great elec vehicle base. If you removed the fuel tank, engine, transfer and gear box, prop shafts. The weight you would save would give you some serious battery space / weight. You could fit a lot of cells in between the frame rails. Ok the chassis is heavy but the body is already aluminium. You could bolt two motors directly to the axle diffs and have perm drive to all 4 wheels. It's like having the center diff locked but also being able to turn corners. |

Agree the tech is not there today, but one day it will be.
To replace diesel completely HGVs will need to find a power source as dense as diesel in battery / hydrogen form. When that happens the defender would be prime for conversion. Current state of the art lithium ion batteries are about 1/10th the energy density of carbon based fuel. Give an electric motor is 70% efficient and a petrol one 20% (at best) eventually I can see batteries that will fit into the same space as the fuel tank. As we'll need around a batter 1/4 as efficient as diesel to make it worth while. As for the other points they can all be overcome - I wouldn't say an electric defender is a bad idea due to all the edge cases mentioned. |

This is missing a trick. Solar panels on the roof. An easy 100kw of space available if not way more. Suddenly the range is expanded making it practical. Rhubarb and custard let fly with their secret weapon.

Either way I can't imagine it will be cheap or easy to do. It's not the same as fitting a bigger engine
I'd rather keep the diesel or fit a petrol engine use the Defender for fun and buy something else to run around in. |

I like the pass through for carrying long items. I wonder what else may be possible without the package constraints of a conventional engine and drivetrain.
A centre seat, forward control should be possible on the same platform, milk float style! That would give a big flat load bed for pallets or boxes. Maybe a drop side option. Camper conversion? Add on a beaver tail and you've got a recovery truck for Prius', Leafs and Teslas. I can't figure out why the winch is hydraulic. The added expense and complication of pumps and hoses can't be practical when an electric winch would do the job. They do need to sort the styling though, tidy it up a bit. Wether we like it or not, this is the way the world is going, eventually. My guess is there will be a hybrid version of the new Defender early in it's life. |

Bankz,
"Farm work, useless" Why would an agricultural vehicle with 150 miles range be useless? Run it to the mart with a trailer, recharge while there (if necessary), run back to farm. |

Ugly? What drugs are you guys on? That is absolutely wonderful!! Yes, it's designed by a 5 year old. Basically the Defender was too. Clue: it was never designed. Basic box shape, keep things simple and modular, easy to repair. They've done a wonderful job utilising the benefits of an electric engine by rearranging the internal space and you will actually get better offroad ability with electric: two motors, lots of torque, but easy to control at all ranges.
True, the range is slightly limited but I desperately want one. Way more than anything in the Land Rover stable right now, and more than I'm likely to want the Defender replacement. |

What are you guys on about?
Portal axles Modular design Twin motor (fully manageable torque to both axles) Polyurethane floor panels for washability Battery weight low down to increase stability Massive approach and departure angles, and nothing to get broken underneath Adjustable suspension Large ground clearance Independent suspension with large axle articulation Smooth 0–100% torque Electric motors are actually simpler than diesel/petrol Riveted panels (easy replacement) Power takeoff from regular electricity plugs Front can open for long loads (genius!) Could theoretically wade to any depth without snorkel (if electrics are sealed) Acceleration and top speed for the commute Convertible to pickup Aluminium construction Square shaped for loads Nice rugged Defenderesque look This is the kind of vehicle Land Rover should be doing, and a true Defender for the 21st century. Top Gear has some more: https://www.topgear.com/car-news/electric/...le-road-ev Oh apologies, I didn't realise I had stumbled onto the wrong forum! Sorry, I don't need a haircut today. |

Don't worry about them, they can't see past their nostalgia for something you can no longer obtain and that in truth should have been abandoned back in the 1970s. Rhubarb and custard let fly with their secret weapon.

Actually, when you look a bit deeper and see the thing in action in the several videos of it on YouTube, you have to admit that it is actually pretty impressive. Pretty, no, pretty impressive, definitely!
Its one major flaw is the very short range and the fact that it takes 7 hours to refuel. In every other respect it actually looks very good. |
