I’ve been a big fan of the Nissan Leaf for a long time, but there’s always been a little bit of a question mark about its energy efficiency.
If you’ve ever taken a look at how many miles per gallon a fuel cell Nissan Leaf can run, or how many gallons of gas it can produce, it’s clear that it’s nowhere near the efficiency of a diesel.
The Leaf’s fuel efficiency is, however, a lot better than that of a gasoline-powered car.
Nissan’s fuel cell has been on sale for some time now, but it’s only now that the company is starting to make its first commercial production models available.
I’ve driven both the Leaf and the Leaf EV, and I think it’s safe to say the Leaf has a much better fuel economy than the more powerful, but much less fuel efficient, diesel.
What’s more, I can safely say that the Leaf is far more efficient than any gasoline-electric car.
I’ve been testing the Leaf with my new Focus ST, and while I can’t say I’ve nailed down exactly how the Leaf compares to a diesel, it is far better than any other gasoline- or electric-powered vehicle I’ve driven.
So what’s going on?
First of all, let’s look at the engine.
Like most of the other cars on the market, the Leaf uses a 3.7L V6 engine, which is a new model.
That engine, coupled with a six-speed dual-clutch transmission, produces a peak power output of 742 horsepower at 6,000 rpm and 704 lb-ft of torque at 6:30 mph.
At the heart of the Leaf’s powertrain is a 5.0L V8 that powers a six cylinder, four-barrel carburetor.
While the powertrain produces about 1.5 horsepower more than the engine, the torque output of the powertrains is a lot less.
Compared to the 3.5-liter V8 in the Ford Fusion, the 5.7-liter engine produces only 1.6 hp more and 3.9 lb-force more torque.
On a normal highway, the power from the 5-liter and 4-barreled V8s should be sufficient to push the Leaf to 60 mph in just under 7 seconds, or about 7 seconds faster than a diesel and 4 seconds faster even than a gasoline car.
It gets better.
Of course, there are some caveats to consider here.
First, the Ford engine is a hybrid, meaning it has both a gasoline engine and an electric engine.
It’s a little different in terms of how it works, but this isn’t an issue in the real world because most gasoline cars and trucks have a gasoline motor and an EV engine.
(The exception is the Toyota Prius, which has a diesel engine and electric motor.)
The same goes for the Nissan engines.
Even though the Leaf engine uses a hybrid system, there’s still a lot of power left in the cylinders.
This means the fuel efficiency of the 5th-generation Leaf is still quite good.
Second, as a hybrid vehicle, the Nissan engine produces power in both cylinders.
That means the 5 th-generation’s power output isn’t as impressive as that of the previous generation, but that doesn’t mean the 5 lt’s performance is any worse.
In addition, Nissan says the 5L engine is the fastest in the industry and that it delivers “great torque and low noise.”
Finally, unlike most of its competitors, Nissan has included a rear-drive system in the Leaf.
All of these factors make the 5lt the better car in terms for efficiency.
And it’s just about perfect.
When you’re comparing the power output and efficiency of different engines, you’ll notice that the power-to-weight ratio is the same across the board.
And if you look at horsepower, the 6.4L Nissan engine is actually more efficient in terms, than the 4.7 lt, the 3L and the 2.9L diesel engines.
In fact, the efficiency is so great that the efficiency rating of the 3lt is the lowest of any gasoline engine that I’ve tested, but the 3 lt is about 20 percent better than the average diesel engine.
That efficiency rating is good for a hybrid engine, and even better for a 5L and 5L+L engine.
