The car has multiple settings for power (torque), Multiple traction control settings, comes standard with Bluetooth compatibilty, Bose Stero, great breaks, and a transmission meant for vehicle with more horsepower..... And you think the Abarth should start at $15,000????? You can get an abarth for 23,000 with the stripes and all I mentioned above
@NIGHTMAREuki More variability. The original VTEC, for example, had two modes, but my understanding of Multi-Air is that it varies continuously and fluidly to optimize the timing, with the ability to change the open-close profile to almost any shape. Other variable valve timing systems, from what I understand of them, simply open the intake valve with the cam profile at different times to achieve an optimization, rather than creating "custom" cam profiles on-the-fly.
Award for "the worst camera man on earth" goes to..... See above. Wow. When I guy is talking about intake technology, I don't wanna see the crank pulley :(
Multi-air is completely different. The systems toyota, bmw, honda and many others are more limited. The multi-air system, vary both the phase and the composition of the mixture, since low rpm. to high rpm. May delay the time of detonation can open the valves to allow for cleaning between cycles or even outside cycle. The fuel can be spread over thousands of shots before being detonated. Nothing in Multi-air is static, everything can be changed.
Sarich Orbital Technology....designed in Australia, sold to the highest bidder! GM have the technology too , thanks to the shared partnership that Fiat has with them in their engine technology.
Trying to understand WTF he's taling about but I don't really get it. The video needs a graphic to go along with his narration, not the camera going all over the place and cutting to random crap.
No it isn't. Those systems are just variable valve timing. They still use a normal throttle body (aka the "throttle butterfly") so you still lose about 10% fuel efficiency at part loads due to "pumping losses" (best google this for a proper explanation). In the multiair, they eliminate the throttle body, and control power solely through deactivating the intake valves partway through their action, thereby eliminating all pumping losses at part loads.
this is not something new and advance.It is almost there more than 30 years. FIAT named it as MultiAir,in TOYOTA they calll it VVT,in HONDA is VTEC,VANOS is the name for BMW. it just a common technology available in most of European car. they just never mention that.

Is this engine also used in the 2013 Dodge Dart?
Its hard to understand with the terrible camera work. How about some close ups of items he's talking about?

@76carmel Yes it is. Check out our new Dart video for more details on the MultAir engine.
Best sounding 4 in years. I don't know how reliable this will be in the long run. We will see.
76k on my 2013 abarth. So far so good, God Bless
@@bootafromune1 the word is good on the abarth blown motor.
@@fatboy19831 wow you replied after 9 Years, That's rare.
how is that different from variable valve timing?
Its like a Vtec from future!! this controls the entire timming its perfect not just high rpm range so you dont have to drive like you stole the car ;)

so its like controlling vtech pretty much?

I like it is it the same in the cx_5
Unfortunately..This engine is using timing belt not timing chain😔
So it's kinda like toyotas VVT-I but with more air pressure and amount that goes into the engine.
