Unlike previous year, Yamaha has changed the drive train. New cart does not have the quick acceleration similar to previous years. Takes a bit to get to 20 mph so you need to be careful pulling out in traffice. Otherwise nice cart.

The only drive chain change was to go from 13 hp to 11 hp and add independent suspension. Yes it accelerates a little bit slower, but oh so much more quiet. Still will go just as fast as the older carts. The only place I even notice it is coming out of the tunnels and going up the ramp.

For me the quiet and smooth ride is so worth the slightly less acceleration.

We have a 2014 Yamaha EFI. When, shopping for it I seem to recall the HP was listed at 12. Frankly, I was mostly decided to buy a club cart because it is or was rated at 15 hp and has or had pressurized lubrication unlike the Yamaha which has only simple splash lubrication. The dealer for Club Cart killed the sale. No one including their service guy knew anything about the gas carts.

To our pleasant surprise, Villages Golf Cart gave us a loaner
for an oil change. I laugh-you cannot be without a golf cart in the Villages. The loaner was a 2017. It was clearly faster than our 2014 and from a start, it had a hair trigger.

Mr reading shows the 2018 is 11.4 HP. Math or it has gone down slightly. Apparently, they've reduced the emissions.
They also claim 45 mpg. Not sure but I think my 2014 EFI
gets about 30 mpg. Not at all a problem. We use it quite a lot and use about four gallons a month.

"Cutting into traffic," this thought is endlessly posted on this website. Golf cart-you should not be cutting into traffic. Cars have the right of way.

A little smother and slower acceleration would be nice when golfing : )

Mine seems to hit 20 rather quickly, I never had a golf cart with a speedometer before and this one goes as a high between 20.9 and 21.1 on a level section of road. I guess it really doesn't matter what the power is as they most likely won't be changing these for the next several years so you get what they make or go elsewhere. Only mistake I think I made was not upgrading the tires as the stock tires are a little rough and quite noticeable until they get warmed up.

My 2013 Yamaha, noisy, fast and always 50 mpg!

How were you able to get it to go that slow ?

Not really that fast, but noisy and 50 MPG.

2017 Yamaha also has independent suspension and has Quietech noise suppression. Main difference between the two is slightly less HP in 2018.

Agree, When merging into traffic you should do so when is safe when wanting to make left hand turn. You don't stop in diamond lane and try to cut across traffic, that how you get killed. On non diamond lane street carts are like cars they have and have to give the right way IAW traffic laws and regulations.

My 2012 YEFI gets over 40 and has high as 47. Heck my Honda get 28 mph you would think lawn mower engine would get better. Splash or pressurize not really factor it's lawn mower engine by design and checking/changing the oil regularly will make or break it.

If you read the Specifications in your manual (chapter 10) you will find (starting in 2017) the transaxle gear reduction is 9.789 in forward and 14.358 in reverse. Before Yamaha redesigned the cart in 2017, everybody would replace the rear end gears with 8.1, it came out of the factory with 12.xx. (Some builders didn't change the rear end gears, those carts are running a lot more RPMs going 20 MPH. That puts a lot more wear and tear on the engine.
It has been explained to me from a Yamaha Engineer that the higher the gear reduction number the faster off the line, the lower the reduction number the slower off the line but at top end the engine is turning LESS RPMs. Less stress on the engine. Find a friend who has an older Yamaha and go to a parking lot where, no one or cars are around and race off the line see who wins the short race (50 feet). Let us know what happens.

You must be filling the tank up to th neck. Being the filler neck is sunk in the top of the tank I find that you can be off by 1/2 gallon or so from one fill up to then next which can make big difference in comparing MPG from one tank to another. I documented my miles and tank fill ups for 6 months. Average MPG was between 42 and 47 in my 2012 EFI.

I have been keeping records of every gallon and every hour for the past 12,000 miles on this cart. 50 MPG. Sorry, but true.

I also get 50 mpg with my 2014 Yamaha EFI.
