How fast is a Z71?
At the track, the 2021 Suburban Z71 ran to 60 mph in 7.6 seconds and through the quarter-mile in 15.7 seconds. Chevy’s spacious three-row SUV steps up its handling game in a big way.

What gear ratio does a 4L60E have?
While the 4L80E uses a 2.48 First and 1.48 Second gear just like the TH400, the 4L60E has a 3.06 First and 1.63 Second, which was a holdover from the 700-R4 and better suited to a dump truck or the anemic 305s of the era.
How do I know my Chevy gear ratio?
Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.
What are the gear ratios in a 4L60E?
Taking the 4L60E Into the 21st Century Performance World
The main hiccup on the 4L60E is its gear ratios – 3.06 in first and 1.62 in second, which meant you were getting a massive amount of torque in first gear, before dropping down to about half that power in second.
Is 3.55 or 3.73 gears better?
PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.
What gear ratio is best for highway?
If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31. This applies to highway driving; city driving mpg isn’t really affected by the axle ratio. If you do a mix of both, go with the “standard” axle ratio offered by the manufacturer.
What axle ratio is best for towing?
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
What axle ratio is better for mileage?
The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.
Does axle back exhaust increase mpg?
The cat-back system improves airflow, which means the engine doesn’t work as hard to eliminate exhaust fumes. The reduced resistance minimizes the load on the engine, which leads to less fuel consumption. That said, the vehicle miles per gallon (MPG) or fuel economy increases in freeways and city roads.
Do axles affect gas mileage?
The choice of a numerically higher axle ratio will only knock off about 1 mile per gallon from the truck’s fuel economy. But since pickup truck fuel efficiency is low to begin with, even a 1 mpg reduction is significant.
What is the best fuel ratio?
The science behind air fuel ratio
The scientifically “perfect” mixture for normal petrol is 14.7:1, that is 14.7 times the mass of air to fuel. However, that doesn’t mean a car should run at that. For optimum fuel economy 16-17:1 is usually best, leaner than that and the car will begin to misfire.
What rpm is best for fuel efficiency?
Between 1,300 and 1,500 RPM
What is the perfect air fuel ratio?
The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
What is the best air fuel ratio for a gas engine?
It used to be that 12.5:1 was considered the best power ratio, but with improved combustion chambers and hotter ignition systems, the ideal now is around 12.8:1 to 13.2:1. This is roughly 13 parts of air to one part fuel.
Which air fuel mixture gives good mpg?
The 14.7:1 ratio is perfect for idling and light throttle cruising conditions as it’s the most efficient mixture possible, meaning the best fuel economy and lowest emissions.
