Hey everyone. I thought I'd introduce my self. I have been lurking for the past few months and really found some useful info pertaining to my Smart Passion.
I used to daily drive my 2008 Mercedes E63 AMG, but a few months back, bought a 2013 Smart Passion with 37,000 miles. It easily is my new DD. Being that I drive in NY, Queens to be specific, its the perfect car for parking in the city and gas, 20 bucks gets me 200 miles vs 60 bucks for 180 miles in the AMG.

The Smart came with Fogs and Brabus rims


Some weird quirks tho
- I have to really step on the brake, or else the car inches forward when in drive.
- There is some strange rattle sound when I drive her thru first gear after starting her in the morning.
- Vibrations from the engine.

I take it these are normal things?

feeding and maintenance are a *****. i had a new C300 as a loaner a year and a half ago, great highway cruiser, not so fun to feed and park. weird, MB is getting cheap, used to be the name was the engine size, but the C300 was a 2 liter 4 cylinder turbo. then again, my old MB 190E had a 2.3 liter 4.

Welcome. You now have two sweet rides!

Used to be the digits represent engine size, but since they squeeze ever so much more output per liter now they switched the idea to equivalent output. So the 300 has the same output as a 3.0 L engine.

The only problem with your Smart is that's it's not an AMG Mercedes. I drove my wife's '16 Honda Accord two door coupe last night. It drives and rides night and day different from my '14 Brabus.

That being said, I love that you have to drive a Smart, it won't drive itself.I love all of the unique characteristics of our cars. I understand the transmission and enjoy driving a clutchless manual transmission. I wish people that review Smart Cars, were people who drove Smart Cars. I'm getting tired of reviewers comparing Smarts to...well...Honda Accords and AMG Mercedes. It's as different as comparing a car to a motorcycle. If you're looking to buy a motorcycle, you want to compare it to other motorcycles, not a car.

Welcome to the world of Smart. Love your AMG Mercedes.

Welcome to our lovely forum!!

The quirks you speak of are pretty normal. :)

-- The 451 has a pretty aggressive "creep mode" that you have to hold the brake against or else it'll move the car forward. Once the clutch disengages you should be able to let off a little though!

-- Take your smart through a drive-through, it'll sound like a bucket of bolts. :D Sadly, our little engines (Mitsubishi 3B21) aren't a super refined powerplant.

-- Engine vibrations are pretty normal-ish. More severe vibrations may be reduced by replacing the lower motor mount with a new one.

I replaced my lower motor mount (old one is still good) to an aftermarket mount which is more solid and I now feel the engine vibrations much more when sitting at a light. (The new mount was for performance.) So if you replace your mount do so with an Original mount to keep the vibrations down...or a performance mount if you want more instant acceleration.

I just installed a Go Pedal and Cold Air Intake on my '14 Smart Brabus. Both mods have made a significant advantage to my Smart's performance. The cold air intake gives the car a much more aggressive sound, which I love.

Do you think a performance engine mount could provide an advantage, after I have already installed the other two mods?

How does an engine mount affect performance, how much does it cost and can the installation be done by the average Smart owner or does it have to be taken to a mechanic with special equipment?

I'm not a mechanic, but was able to install both the Go Pedal (Easy) and Cold Air Intake (Not so much). It took a while and was a pain in the ass to install the intake (Removing the air pipe and air filter box was a royal pain).

It's hard to imagine a motor mount making a difference.

he solid motor mount will give you a touch more takeoff, but you will pay for it with a harsher ride and feel more vibration from the motor. Most of the people I know that had it installed, either regretted it, or changed it back.

One important note, a GO Pedal (see also: Sprint Booster) doesn't actually make your car faster. These devices change the throttle mapping and throttle response time.

As an example: The stock 451's throttle has a response time of a half second. A GO Pedal cuts the response time to half while adding a more aggressive throttle response.

So you move the pedal down 25% of the way. Stock, this would give you about 25% throttle. Do it with a GO Pedal, and 25% could potentially equal 50% or higher.

https://www.sprintboostersales.com/How-It-Works.cfm

The result is that your car 'feels' faster. You aren't actually going faster than you were before, but because the throttle response and mapping, your 'butt dyno' thinks an afterburner has been lit.

It's a long way to answer your question, but yes a performance motor mount would make your car faster. :)

I did know that about the Go Pedal and it's already come in handy a couple of times. What's the cost for installing a motor mount. It doesn't sound like it's a do it yourself type of modification.

Love the "butt" dyno reference.
