Nissan hybrid vehicle prototype uses rear-wheel drive

Nissan pulled the wraps off a pair of prototype vehicles today – one is an all-electric and one a hybrid. Both of the vehicles take advantage of new lithium-ion batteries that Nissan and NEC jointly developed. The two vehicles were developed under the NISSAN GT 2012 business plan.

The advanced lithium-ion batteries used in the prototype vehicles feature a compact, laminated configuration that delivers twice the electrical power when compared to traditional cylindrical configurations. Nissan says that the compact design of the batteries allows for improved vehicle packaging and a wider range of applications when compared to traditional batteries.

The full electric vehicle uses the advanced batteries along with a newly developed 80kW motor and inverter. Nissan says the electric vehicle uses a front-wheel drive configuration and that the advanced laminated batteries are installed under the floor of the vehicle. The laminated design of the batteries means that the vehicles interior and storage space are not sacrificed to battery storage. Nissan says that the full electric vehicle will go into production in 2010 and will feature a new and unique body style not based on existing Nissan vehicles.

Nissan's prototype hybrid electric vehicle introduces a pair of new technologies Nissan says are breakthroughs -- a high-performance rear-wheel drive system and a parallel-powertrain hybrid system. Nissan says that both the hybrid technology and the rear-wheel drive are original designs -- in this case, the system is placed within a 2010 Infiniti G37 Sedan.

Nissan's parallel-powertrain system connects one motor directly to an engine and transmission via two clutches. This layout allows the vehicle to switch between the dual clutches to optimize and conserve energy utilization and improve fuel-efficiency. Nissan says its parallel-powertrain eliminates the need for typical torque converters and contributes to higher responsiveness and linear acceleration.

Nissan describes the action of the hybrid system as:

  • Idle-stop: The battery is used to power the motor to save on fuel.
  • Regular driving: The engine is used to power the motor as well as regenerate the battery.
  • Acceleration: Both the engine and battery (power assist) is used to power the motor to achieve smooth acceleration.
  • Deceleration: Energy from braking is conserved and re-routed back to regenerate the battery.

Nissan isn’t alone in introducing new hybrid vehicles. Yesterday DailyTech reported that Honda was bringing the Insight back to the U.S. as a 2010 model for an MSRP of $18,500. The Insight is rumored to get over 70 miles per gallon.

One question I have

Nowhere in the article does it mention estimated MPG... I would think any hybrid article would have that information.

Still, Nissan is a good company and I'm glad they're getting into this game. It sounds like it will be a decent vehicle.

The Insight is made by Honda. It is an entirely different automobile manufacturer.

That's a Honda referenced from a few days ago. The two Nissan models are prototypes and no information has been released yet on MPG or range.

I'm sure it'll be a fun car to drive, but it'll be pricey, and I'd be surprised if it reached 30-35 mpg. I'm still relatively convinced that fun + efficient = turbo.

So algebraically

efficient = turbo - fun
fun = turbo - efficient

Sounds about right.

I love Nissans, if they're 3rd Generation Maximas..

5th Gen and up have been nothing but problems and bad design, engineering and material quality. The new 2009 maxima 4DSC might change that... finally.. but has yet to be verified.

I hear ya. I had a 2006 Sentra SER SpecV. The car would turn like nobody's business, and was alright in a straight line too (except for the massive torque-steer).

Problem is, the 2.5 engine eats oil (apparently from using bad piston-rings) and after 20,000 miles the car started having difficulty starting when warm.

Found out later that EVERY person I know that had a 2.5 engine (didn't matter if it was in a Sentra or an Altima) had the same problem... Probably wouldn't buy a Nissan any time soon...

Mine had the same issue. I had an 04 Spec V. The 3.7L is an entirely new engine than the 3.5L. My neighbor has a G37 coupe and has experienced no problems. I have read good things about the new motor.

My 350z has been problem free for 3 and 1/2 years. The only blemishes are cosmetic. Of course, I take care of my car. Still, the Nissan V6 3.5L engine is second to none in quality. Before my Z, I had a 2001 Maxima with about 70,000 miles on it. No problems whatsoever. Nissan's V4 and V8 I cannot speak for.

Although I love Nissan, I am disgusted that their new Skyline/GT-R does not have a manual transmission. That is just fundamentally wrong.

It DOES have a manual transmission. The clutch is controlled by electronics much like a F1 car. It's got all the manual tranny parts such as, clutches, flywheel, TO bearing, pressure plate, etc. Automatics don't have ANY of those parts. Don't be confused by the wannabe F1-style automatic trannys with paddle shifters, totally different thing as those are STILL automatic trannys.

Why put out garbage numbers now only to be vilified for their inaccuracy later? It looks to be in the very prototype/test-vehicle stage.

Well.....that's kinda Nissan's m.o.

For example, they've claimed GT-R performance numbers for a supposedly "american tuned production car", yet testing at "The Ring" showed that they used R compond tires (not runflats) and didn't run a full lap. Initial cars handed to automotive enthusiest magazines showed incredible performance, but when those same magazined got thier hands on prodution variants, ooops, performance dropped.

Sounds like par for the course to release garbage numbers to generate hype. Surprised they didn't do it here.

I'm still trying to find these mystery magazines as ALL of the magazines I've read were able to reproduce the quick times. I don't see the big deal here.

"Initial cars handed to automotive enthusiest magazines showed incredible performance"

And after they got their hands on it, it showed incredible performance. Go look for the Stig taking it around the Top Gear track (it was faster than a lot of supercars).

So, someone is upset that Nissan did things right?

Am I upset that they tested a "production" car with a non-production tune and non-production tires and passed that off as true production, you bet.

And you call that right?

I was referring to the not-giving of performance numbers that was complained about "above" in this thread.

Does it have to look like a shoebox?
