Nissan Altima Hybrid Debuts at Orange County Auto Show

Altima Hybrid.

Nissan’s first hybrid, the 2007 Altima Hybrid, made its debut at the 2007-Model Orange County Auto Show in Anaheim, California.

Based on Toyota technology, the Altima Hybrid’s powertrain mates a version of the QR25 2.5-liter 4-cylinder engine and electronic Continuously Variable Transmission (eCVT) with a 30 kW (40 hp) electric motor/generator that can develop 199 lb-ft (270 Nm) of torque. The Altima Hybrid’s hybrid system is rated at a net power of 198 horsepower (148 kW) with fuel economy estimated at 41 mpg city/36 mpg highway (39 mpg combined).

Combined with Altima’s standard 20-gallon fuel tank, the Altima Hybrid has a projected driving range of up to 700 miles between fill-ups.

The Altima Hybrid utilizes regenerative braking technology to sustain the charge in 244-volt NiMH battery pack.

Nissan modified the QR25 4-cylinder engine for the hybrid with a larger intake manifold, slightly increased the compression ratio (9.6:1 compared to 9.5:1 in the standard engine) and reduced friction characteristics. The engine also features Nissan’s Continuously Variable Timing Control System (CVTCS) for continuously variable valve timing, modular engine design, microfinished crank journals and cam lobes, molybdenum-coated lightweight pistons and electronically controlled throttle.

The hybrid system-specific eCVT works in conjunction with the Hybrid Vehicle-Electric Control Unit (HV-ECU) to determine which power source or combination of power sources will turn the wheels.

The Altima Hybrid’s electric motor produces high torque at low rpm, allowing it to utilize its all-electric mode (Electric Vehicle—EV mode) to power the car from a standing idle and through initial acceleration without the assistance of the gasoline engine.

After the electric motor provides initial acceleration, the gasoline engine quietly starts and assumes the load of powering the vehicle. The gasoline engine works independently through cruising speeds until the vehicle reaches speeds at which fuel efficiency declines.

When loads require, the electric motor starts again and aids the gasoline engine in powering the Altima Hybrid. This allows the gasoline engine to remain in its ideal rpm range while the axle rpm simultaneously increases due to the extra power being contributed by the electric motor.

A digital display on the speedometer indicates when the Altima Hybrid is running solely on electric power. The Altima Hybrid’s available DVD navigation system also features a real-time display showing how the hybrid system directs the flow of energy.

Classified as an Advanced Technology-Partial Zero Emissions Vehicle (AT-PZEV), the new Altima Hybrid will be available in eight states. The vehicle has been certified to meet California emissions requirements and will be sold beginning in early 2007 in those states that have adopted California emissions regulations: California, New York, Massachusetts, Connecticut, Vermont, Rhode Island, Maine and New Jersey. These states are among the strongest markets for hybrid vehicles.

The new Altima Hybrid is the sixth model in the 2007 Altima lineup, joining the Altima 2.5, 2.5 S, 2.5 S with SL Package and two 3.5-liter V6-powered models, the Altima 3.5 SE and 3.5 SL. The 2007 Altima Hybrid will be available in early 2007, following the November 2006 introduction of the 2007 Altima 2.5-liter 4-cylinder and 3.5-liter V6 gasoline-powered models.

wow, could they pick a more obscure venue to debut the model? no wonder it's only being sold in 8 states...

Dear Nissan:

Well, that's pretty nice,

39 mpg? I personally can't possibly reach that mileage-- [downward]. I can't recall ever getting less than 43 mpg, even driving like a maniac. (My car is a 2003 Beetle, TDI.) On my last tank of biodiesel, I got 66 mpg.

Maybe if you could get the government to go along with a little more modest transportation, like you guys used to make back in the 70s, I'm sure you could come up with something as good as my humble Beetle.

Please.

Realist

39mpg is better than probably 95% of Americans are getting. So, although 66>39, at least its a huge improvement over the average vehicle. Kudos to Nissan.

Dear Ernie,

The Beetle has HALF as much power and no usable back seat for full size adults. You also have about one third the trunkspace and your EPA rating is 34/44 with an automatic transmission, 38 combined, thus worse than the Altima. Your EPA Air Polution score on a scale of 0 to 10 is 0. Yes, ZERO. The polution from an '03 TDI is about 20 times as high as a PZEV car. Thanks for trying though.

On a scale of 0 to 10 I give the EPA ratings system a 0.

Before we use the EPA to settle arguments we have to agree that they know what they are doing.

Cheers,

JRod.

Why would this offering be ridiculed? Nissan produces a sporty, roomy and well-equipped sedan that will likely go 0-60 in a touch over 7 seconds AND get 39 mpg combined? How is that a bad thing?

It cracks me up - some people on this site will never be satisfied until 100% of the public is commuting in Smart cars, Segways, and bicycles.

I wish I could have purchased one of these things two and a half years ago.

On the other hand, I already get upwards of 700 miles on a tank (18.4 gallons, 40+ MPG, 2004 Passat TDI).

See this should have come about instead of the Prius. It should have been family car from the get go.

Nissan living up to the name as the conservative second who learns from other's mistakes.

We have to keep the big picture in mind here, I believe. We've just entered the age of no-longer-cheap oil, and all parts of the economy, including companies and consumers at all levels, are just beginning to adjust.

Sure, I'd love to see the average US passenger car get 60 MPG (or more), but a lot of technological and cultural change has to take place to get us there. The good news is we're definitely on our way.

I think the key to this vehicle, and the Toyota Camry Hybrid, is that they have the potential to replace six cylinder vehicles in the future. I've never owned a 6 banger myself, but it seems that 200 HP is a fair amount of juice. I can't imagine a use for a mid size family sedan where 200 HP just will not get the job done. The hybrid version gets 39 MPG, the 2006 6 cylinder version gets 24 MPG. That is an efficiency gain of 62%. With a slight tweak in the american consumer's mindset, we could see these type of hybrid vehicles start to replace the more inefficelt segments of the auto industry (possible, hopefully, well probably not, but it's nice to hope...)

Peace,
Cosmo

"See this should have come about instead of the Prius. It should have been family car from the get go."

At least Nissan will contribute to the hybrid market offering, improve the avg. market fuel economy and reducing avg. vehicle emissions, not to mention the cloud of emissions from TDIs.

Lets run the numbers on this one.

Over the V6 version, assuming 39mpg combined and 10,000 miles/year, then you’ll save $400 a year at $2.50 gal gas.

Over 5 years that’s $2,000.

If gas is $5/gal, or you drive 20,000miles a year then this becomes $4,000

So to my mind the hybrid can only charge between $2,000, and $4,000 premium over the regular V6 model.

There may be other benefits, such as reduced brake wear, but this may be offset by more complexity, which may in the long term increase warranty/repair costs.
