Will Morgan Build The First-Ever Multi-Gear EV?

Rattle off a list of the buzzworthy EV makers that seem likely to achieve the “holy grail of EV development,” a multi-gear electric car, and chances are that firms like Tesla, Fisker, Th!nk or even a major OEM like Nissan will make the cut. You probably wouldn’t consider the ultra-conservative British sportscar maker Morgan to be in the running, as they still build body substructures out of wood… surely the brand that’s most stuck in the early 20th Century seems an unlikely candidate for EV technical leadership. Think again…

GreenCarCongress reports that Morgan is working on something called the +E, an electrified version of its Aero 8 sportscar, with prototype production scheduled for early 2012. And believe it or not, the plan is to send 221+ lb-ft of zero-rpm torque through a “conventional manual transmission.” That’s right all you Silicon Valley hotshots and US DOE grant-receivers: the most advanced EV may just be developed by a firm that was long said to be “stuck in the 1930s.”

Part-funded by a $166k R&D grant from the Niche Vehicle Network CR&D Program, the +E will be made by replacing an Aero 8’s BMW V8 and replacing it with a variation of Zytek’s innovative electric drivetrain. The Zytek drivetrain, which is known for its extremely compact packaging, is also being used for GOrdon Murray’s T.27 electric city car ( click here for more on the drivetrain). Featuring lithium-ion batteries, the rear-drive +E will take advantage of Zytek’s extensive research into hybrid and KERs technology (the firm supplied technology for the first Grand Prix-winning KERS system).

But the most important development is the use of a manual transmission in an EV application. From the sound of it, Morgan will use the 6-speed Getrag transmission that’s normally mated to the BMW V8… but because it’s not clear how much power the +E will produce, it’s possible that another solution will be used. But the man-tran will definitely make an appearance, as Zytek’s Neil Cheeseman explains

Keeping the motor in its sweet spot will help it use energy more efficiently, which will increase the vehicle’s range. It also allows us to provide lower gearing for rapid acceleration from pull-away and higher gearing for top speed. It should also make the car more engaging for keen drivers.

EVs will make better progress with hard-core gearheads when shiftable multi-speed transmissions are made part of the package, but as Tesla has proved, engineering a reliable multi-gear EV ain’t easy. If Morgan is the first firm to bring one to market, it could radically alter the retro sportscar maker’s position in the industry.

Someone explain why a rev matching algorithm with DSG-style manual transmission would not work. That seems to be the logical answer. For upshifts, the motor controller can brake the motor (regen, anyone?) to match revs with the clutch disengaged. For downshifts, juice the motor to spin it up, match revs, and let regen scrub off speed. The motor would be operating more like a servo. Seems obvious and it is baffling why no-one is trying it. What am I missing?

I'm just posting here because my name is Morgan!

Joe65688619 Under Ghosn they went through the same short-term bottom-line thinking that GM did in the 80s/90s, and they have not recovered say, to their heyday in the 50s and 60s in terms of market share and innovation. Poor design decisions (a CVT in their front-wheel drive "4-Door Sports Car", model overlap in a poorly performing segment (they never needed the Altima AND the Maxima...what they needed was one vehicle with different drivetrain, including hybrid, to compete with the Accord/Camry, and decontenting their vehicles: My 2012 QX56 (I know, not a Nissan, but the same holds for the Armada) had power rear windows in the cargo area that could vent, a glass hatch on the back door that could be opened separate from the whole liftgate (in such a tall vehicle, kinda essential if you have it in a garage and want to load the trunk without having to open the garage door to make room for the lift gate), a nice driver's side folding armrest, and a few other quality-of-life details absent from my 2018 QX80. In a competitive market this attention to detai is can be the differentiator that sell cars. Now they are caught in the middle of the market, competing more with Hyundai and Kia and selling discounted vehicles near the same price points, but losing money on them. They invested also invested a lot in niche platforms. The Leaf was one of the first full EVs, but never really evolved. They misjudged the market - luxury EVs are selling, small budget models not so much. Variable compression engines offering little in terms of real-world power or tech, let a lot of complexity that is leading to higher failure rates. Aside from the Z and GT-R (low volume models), not much forced induction (whether your a fan or not, look at what Honda did with the CR-V and Acura RDX - same chassis, slap a turbo on it, make it nicer inside, and now you can sell it as a semi-premium brand with higher markup). That said, I do believe they retain the technical and engineering capability to do far better. About time management realized they need to make smarter investments and understand their markets better.
Kwik_Shift_Pro4X Off-road fluff on vehicles that should not be off road needs to die.
Kwik_Shift_Pro4X Saw this posted on social media; “Just bought a 2023 Tundra with the 14" screen. Let my son borrow it for the afternoon, he connected his phone to listen to his iTunes.The next day my insurance company raised my rates and added my son to my policy. The email said that a private company showed that my son drove the vehicle. He already had his own vehicle that he was insuring.My insurance company demanded he give all his insurance info and some private info for proof. He declined for privacy reasons and my insurance cancelled my policy.These new vehicles with their tech are on condition that we give up our privacy to enter their world. It's not worth it people.”
TheEndlessEnigma Poor planning here, dropping a Vinfast dealer in Pensacola FL is just not going to work. I love Pensacola and that part of the Gulf Coast, but that area is by no means an EV adoption demographic.
Keith Most of the stanced VAGS with roof racks are nuisance drivers in my area. Very likely this one's been driven hard. And that silly roof rack is extra $'s, likely at full retail lol. Reminds me of the guys back in the late 20th century would put in their ads that the installed aftermarket stereo would be a negotiated extra. Were they going to go find and reinstall that old Delco if you didn't want the Kraco/Jenson set up they hacked in?
