TTAC tested the m35h
Starting at the front of the car and working your way back, you first find a Nissan 3.5L V6 engine running on the Atkinson cycle (like most hybrids) putting out 302HP and 258lb-ft of twist. After the engine sits a dry clutch pack that allows the engine to start and run while decoupled from the electric motor. Next up we have a 360V AC motor that’s good for 67HP and 199lb-ft directly coupled to the Nissan 7-speed automatic transmission. Located inside the rear of the transmission is a wet clutch pack that allows the engine and motor to be connected with one another to charge the batteries with the vehicle stationary (it also slips to help make gear changes smoother). Decoupling the V6 reduces mechanical losses boosting the electric drive efficiency; this is an area where Honda’s system suffers. Behind the rear seats a 1.4kW lithium-ion battery, wedged where you’d put the 5th bag of golf clubs (Infiniti says a quartet of golfers can still be accommodated and they kindly print a diagram in the trunk to tell you how to manage it). And the final change is a tall 2.6:1 final drive ratio allowing the V6 to spin leisurely on the freeway (1,600RPM at 60MPH).

Hybrid systems like Toyota’s Hybrid Synergy Drive combine the motor and engine numbers in a way that is not simple addition (google is you must know why), however Infiniti’s system is easy to figure: the peak number is achieved where the HP and torque curves of the engine and motor meet, making the M35h good for a combined 360HP at 6,500RPM and approximately 410lb-ft at 5200RPM. Note: Our combined torque number is an estimate as Infniti does not officially list a combined rating; the “online” 457lb-ft numbers floating around are not accurate according to Infiniti because when the V6′s 258lb-ft peak does not align with the motor’s 199lb-ft peak.

The high torque of the electric motor from very low RPMs make the M35h far faster than the numbers on paper would imply, we easily recorded 5.2 second runs to 60MPH with our lowest taking only 5.03 seconds. The low 1.9 second sprint to 30MPH (the M56 takes 2.3) is perhaps the most telling number because by the time the spedo crested 100 the M35h had lost its lead on the V8 powered M56 clocking a 13.5 second ¼ mile at 103MPH (vs 13.4 at 106 for the V8). Part of the reason the performance is so good is the weight gain, at only 276lbs heavier than the M37, the M35h manages to be 99-lbs heavier than the M56 and slips in just below the AWD M56x on the scales. (The Lexus GS450h is only five pounds heavier.) Stoplight racers be warned however, that after a few 0-60 runs the battery and motor heat up enough that the control circuitry puts the kibosh on at least a portion of the electric assist and by the 6th back-to-back 0-60 run our times had risen to 6.2 seconds.
Review: 2012 Infiniti M35h Hybrid | The Truth About Cars
And this is the edmunds track testing results on the 2012 M35h
Test Results:
0-30 (sec): 2.2 (2.3 with TC on)
0-45 (sec): 3.6 (3.7 with TC on)
0-60 (sec): 5.2 (5.4 with TC on)
0-60 with 1-ft Rollout (sec): 4.9 (5.0 with TC on)
0-75 (sec): 7.6 (7.8 with TC on)
1/4-Mile (sec @ mph): 13.5 @ 102.9 (13.6 @ 102.8 with TC on)
Braking
30-0 (ft): 30
60-0 (ft): 119
Handling
Slalom (mph): 63.7 (61.6 with TC on)
Skid Pad Lateral acceleration (g): 0.84 (0.78 with TC on)
Sound
Db @ Idle: 42.5
Db @ Full Throttle: 76.4
Db @ 70 mph Cruise: 64.4
1.9 seconds to 20mph. 5 seconds 0-60. 1/4 mile in mid 13s.


Is there anything else in the category with performance results like this that gets the kind of mileage of the M35h?



With that said. The Q50 SHOULD be lighter than the M35h right?



What do you think the performance results of the Q50 will be? 0-60? 1/4mile?


Will we touch high 4 second 0-60s? I'd imagine with better tires the M35 could likely hit 4.8 4.9 seconds.

G37 Sedan:
3,701 lb (1,679 kg)

M35h
4300 lb (1955 kg)
Those are great number and is only from the m35h but if you look at the weight difference as ^ mentioned. Those numbers will be even better. I have a lot of faith in the Q50 Hybrid and I never like hybrids because of how restrictive it is to performance but here is where the game changes and it starts here with the Q50.

I wouldn't doubt the Q50 hybrid will be faster vs the M35h.

power to weight ratio is key here

4,129lbs is the weight of the M35h in 2013.

3,628 = 2012 G37 Sedan

Even with the hybrid system it should be lighter than 4129lbs.

I wonder how much the hybrid components weigh? Considering the weight should be far off from the 2012 g37 sedan the hydbrid components might add a bit of weight to that but its still gonna be hella fast.

Without a doubt, the hybrid is going to scream. It is nice to live in a world where increased performance does not necessarily mean a corresponding decrease in fuel economy.

What other car out there will put up a challenge to the new hybrid Q50 with similar horsepower range and mpgs? And even car critics like sebastian vettel loves the handling and power of the Q50. Not sure if the hybrid is for me but I will be looking forward to driving one.

I really cant think of any other car that is a hybrid sedan with similar performance to the Q50.

Maybe the GS350 hybrid?
This makes me wonder why Lexus never made a Lexus ISh. Only thing that comes close is the Lexus CT, but no one that originally wanted an IS would get a CT.

Although the GS350 comes closest it's still out of the Q50's class.

There is a 3 Series Hybrid actually that puts out 330 BMW HP which is about the same amount as the Q50h rated at 354 HP. Lol

I guess the hybrid market is still fairly new and no one is going to take the risk at the moment but as soon as a few more manufacturers starting adding to the segment, there won't be a huge competitor for the Q50h.

Why would the GS350 out of the Q50s class? It is a little bit larger and more expensive. They are both V6 hybrid sedans. Both Japanese luxury. I know the GS probably competes more with the M hybrid but the Q50 hybrid can also be compared.

You can not even being to compare the CT200h. To me it is a dressed up Prius.

I never was a fan of the CT200h it is pretty much a prius in a hatchback form. Those things never got popular, if anything its gonna fall of the chart soon with Lexus. I wouldnt even compare that to a Q50. Its a compact.

it's also in a different price category, performance category, different car type, different anything.

Only resemblance between the CT200h and Q50 is that they are both cars.

The lexus Hybris is a totally different system then the one in the M35H and Q50H. The lexus hybrid does not work together with the gas over a certain speed. So if you are doing alot of HWY miles then the Lexus is going to be running on all gas where the Infiniti runs on gas and electric at higher speeds. Acura is working on a system in the RLX I belive where there will be a hybrid motor attached to each of the back wheels and the front wheels will be powered by gas making it AWD hybrid power to the rear and gas to the front .. I want to see what that car will do in MPG and performance!

that was a good one. I dont think infiniti has a vehicle in that category to compare with the CT200h not that it should even have one in the first place. The Q50 is a much more superior car then that.

How does the Q50 hybrid work? I don't really see to much info out there on its system.
