Infiniti M Hybrid
Infiniti's M Hybrid undercuts the Lexus GS 450h and offer better fuel economy

We've talked about Infiniti's upcoming M Hybrid on a number of occasions here at DailyTech. Today, however, Infiniti released official pricing for its large hybrid sedan -- the vehicle will be priced from $53,700 in the United States.

That $50k+ price tag will get you a luxury vehicle that is rated at 27 mpg in the city and 32 mpg on the highway (29 mpg combined). Those number won't blow anyone's socks off, but they are much higher than what you'll find in the non-hybrid $47,700 M35 (18/26 city/highway) and $59,100 M56 (16/25). 

"We're excited to be able to bring in the new Infiniti M Hybrid – with its exceptional blend of power, efficiency, style, luxury and technology – at an M.S.R.P. of under $54,000," said Infiniti VP Ben Poore. "Competitively priced, though with little real direct competition, we expect the M Hybrid to continue the strong sales momentum the new Infiniti M Sedan has been experiencing since its launch in the 2011 model year."

Instead of using the more powerful 3.7-liter V6 found in the G37 and M37, the M Hybrid makes use of a 3.5-liter V6 that produces 292hp and 258 lb-ft of torque. The electric motor adds another 68hp and 199 lb-ft of torque, and is powered by a lithium-ion battery pack.

The M Hybrid can drive up to 62 mph on battery power alone and can travel up to 1.2 miles on battery power before the gasoline engine has to take over. 

For comparison, the Lexus GS 450h (which has been on the market for a few years) is rated at 22/25/23 (city/highway/combined) and has an MSRP of $58,050.

This is a great example of wasting resources, technology and money. Why not lighten the gasoline only car and obtain the same MPG rating without the needless battery and electric motors?

As much as I like new techs coming up, I have to agree with you.
The idea of having one engine (electric) for lower speeds and one for higher speeds and longer travels (gas) seems nice. But there is one big problem, the car always have to carry the weight of both engines, even if it's only using one.
So until we have a good way to store all that electricity (better batteries, fuel cells or whatever), a better power grid and a fast way to recharge, I can't see people abandoning their gas powered cars any time soon.
Some hybrids might even have a better millage when compared to their ordinary counterparts, but I'm not sure it is better enough to justify manufacturing a whole new engine and battery system for the car.

We should all just drive an Ariel Atom.

That'll keep people who shouldn't be behind a wheel off the road.

Yeah, cause they'll all be dead.

Thanks for explaining the joke.

(Having trouble w/the spam filter here so I'm having to leave out links.)
Might? They almost all do. Take a look at which cars get the best economy by Googling for "most fuel-efficient cars consumer reports". Take into account their size, weight and how much power they have.

Look at the Camry and Fusion Hybrid vs. then non-hybrid counterparts by Googling for "Best worst fuel economy". Look at city and overall mileage. There's no non-hybrid Prius but probably the closest comparison is the Toyota Matrix (both have 1.8L 4 cylinder engines). The improvement is quite large.

If you look Google for "Fuel economy vs. performance consumer reports", you'll see the Camry and Altima hybrids also have faster acceleration than their non-hybrids to boot.

As for "whole new engine and battery system..." in Hybrid Synergy Drive cars, there's no starter nor an alternator. The two motor generators are integrated into the transaxle (power split device). The PSD is relatively simple w/only a single planetary gearset (Google for "planetary gear" go to the result then click on Planetary Gear Set) and no internal clutch packs.

Compare that to what an automatic looks like inside. I posted some pics you can see if you Google for "Aisan 6-speed FWD Tokyo Motor Show in 05" and go to post 12.

It's a large luxury car, tailored towards those who don't care about wasting resources, are interested in "cutting-edge" technology, and have money to blow. The addition of this "needless" hybrid system drastically increases the fuel-efficiency above most other cars in this class.

While that may be true for some out there, I think that it is so people who would normally buy the standard version will buy the Hybrid version so they can show everybody how environmentally sensitive they are.

Most people like that don't really have a clue about the environment anyhow, but like the image it gives them by purchasing such items.

Unfortunately, I don't know how heavy the battery is in the M hybrid but since the NiMH in the Prius is only about 100 lbs and Nissan they went li-ion on the M hybrid, I doubt it's much over 100 lbs.

There's only a single electric motor for propulsion in this hybrid.

Unfortunately, lightening cars has consequences too and can compromise safety or cost a lot of in terms of more exotic materials. It'd also be very difficult to get really good city mileage since non-hybrids must run their gas engines at low speed (which is inefficient) and all braking energy is wasted as heat and brake dust instead of being partly recaptured and repurposed for later use. Also, almost all non-hybrids needlessly run their engines while stopped.
