Multiair V6

In this week's autocar I see

"the Multiair top end is modulat and can be fitted to other existing engine blocks. Fiat is working on a 2 cyl and a v6"

I knew about the 2 (for the 500 I believe) but the v6 is a new one on me. Could be interesting.

I also read that the technology will be available for diesels and unlike the multijet system which they sold to Bosch, they will keep hold of the patent to this system and license to other manufacturers.

My reading so far on the system seems to show that this is a real ground breaking advancement in petrol and diesel engines and once again establishes the FIAT group at the top of technological invention.

Good shout I say!!!

If a 2.4 JTD can be remapped from 210 to 250 BHP, I think we could potentially be seeing 300 BHP diesels, wow, that's gonna be quick!

The 3 litre V6 has been on the Fiat Powertrain Technologies road map for some time. It actually features Multijet2 technology and doesn't make any mention of MultiAir - I think thats Autocars inaccurate journalism to blame. I think its a diesel too

I believe it would be an option in the Guilia (159 replacement) rather than the current cars - but you can always hope, pray and save a lot of money. reported early in 2009 >>>>

" Multijet 2 now represents the next leap forward in refinement of the fuel delivery process. It consists of a brand-new system of injection pump and solenoid injectors, which will be supplemented in time with a further twin-piston pump development. The main improvement over existing Multijet injectors is in the system’s further improvement in the ability to finely control the fuel flow, to the notable benefit of emissions and low-mid-range torque.

Originally scheduled to reach production in late 2008, a slight delay in starting production means that the first SDE-engined cars with Multijet 2 should start appearing in production cars from September. With tighter Euro 5 emissions regulations being enforced from the beginning of that month, Multijet 2 will make a significant contribution to cutting NOx emissions without consumption and noise penalties, thanks to its ability to manage multiple injections with greater flexibility than the earlier Multijet system.

According to Alfredo Altavilla, CEO of Fiat Powertrain Technologies, Multijet 2 “will provide the same calibre of advantages as the original common-rail systems did 10 years ago”. Speaking to Engine Technology International magazine last year, he added that the results provided by the technology have been better than anticipated. “We have the (3-litre) V6 Multijet 2 diesels in test mules and the results for performance and CO2 are beyond our expectations,” he said. “We’re aiming for a base CO2 rating on the 3-litre Multijet 2 of 150g per kilometre.”"
