Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

It is a hybrid, but there are categories of hybrid called Serial and Parallel. Parallel hybrids use both power from electric and ICE motors for traction while Serial hybrids use exclusively electric traction motors.

Serial hybrids were tried a few times but they were designed by committee and sucked ass. The first generation Chevy Volt was mentioned in other comments, but no one mentioned how awful it was to drive. The car was super cramped for your average american and it has an extremely undersized electric motor that only output 88 kW. But the gas economy was great - you could reasonably get 100 mpg.

Tesla was only just beginning to gain popularity and show that a BEV with a properly sized motor is a great vehicle. So, naturally, Chevy decided to take that lesson and ignore it when they redesigned the second generation Volt to be a parallel hybrid. Idiots.

Btw when purchasing a hybrid, consider that it has the drivetrain of two cars - twice as many failure points and it requires specialist mechanics. BEV *should* be 1/3 the parts and 1/5th the failure points of their PHEV counterparts.

That aside, there are a few other projects out there that are planning to add a range extending motor to a BEV. Notably the new Scout SUV is going to have that option. Honestly I'm pissed that we haven't seen this approach in more performance oriented vehicles where they could optimize to have the battery sized for roughly 50 km of high intensity driving with a lightweight generator to give it a normal range. I'd fucking love a Miata of that style. Instead all of the performance vehicles have a battery the size of a house and they make it a CUV. Uhg.

Hybrid systems can be more reliable than traditional ones. Hybrid transmissions can be much simpler than traditional transmissions because the electric motors are capable of providing a lot more low end torque than an IC engine. The engine may still be used to drive the wheels but the load on the engine is much more consistent due to the electric motors taking the grunt of the load under acceleration/deceleration.

It's not more reliable if you still have the ICE engine. They've got a million friggen moving parts for the sake of allowing for efficiency and a wide torque band. There's a reason old vehicles are looked at as more reliable - even though they still fail, they have fewer parts to maintain and replace. Modern engines are an insane jumble of "why's this there" and everything is crammed into the smallest package possible.

I notice this in mine. The electric motor does most of the speed changing work. From stop to start is obvious, but also while changing speeds once moving. The tachometer reads pretty consistent, but the electric motor adds the speed.
