Passat R36 / Passat CC V6 FSI

Hey guys

Just wondering, is the engine in the PASSAT CC V6 FSI the same as the engine in the Passat R36? only difference I could gauge was that the R36 had a slightly higher rev limit redline?

[genkifd]

pretty sure they are exactly the same.

They should be - in 2010 VW listed the same power and torque outputs for both, and i think the acceleration and fuel economy stats for both were pretty much the same too. I suspect that the gearing is slightly different, and possibly the intake/exhaust might be configured differently for a more aggressive engine note in the R36?

My R36 does around 2500rpm at 100km/h. What does yours do, GenkiFD?

[genkifd]

at 100km/h my rpm is around 1950.

Just different gearing in the CC to make it more fuel efficient.

Not very effective, apparently. From VW's brochures:

2010 VW Passat CC V6 FSI (brochure date Oct 2010)
10.5l/100km combined cycle
15.5l/100km urban cycle
7.7l/100km extraurban cycle
254g/km CO2
1656kg kerb weight
5.6secs 0-100km/h

2010 VW Passat R36 Sedan (brochure date Feb 2010)
10.5l/100km combined cycle
13.0l/100km urban cycle
8.2l/100km extraurban cycle
233g/km CO2
1681kg kerb weight
5.6secs 0-100km/h

I wonder if some of the cogs in the gearbox are of different ratios in the R36? The fact that the extra-urban cycle is significantly higher in the R36 than the CCV6, while the combined cycles are the same would suggest that the R36 has a shorter top gear or two. I expect that would give it better high speed responsiveness at the expense of fuel economy, while the CC would be a better cruiser (again, as you'd expect). The fact that both have the same 0-100 times would also support this theory.

Wow. Surprised the R36 is geared so low in 6th. I did 2,000klms over the weekend in my CC (Syd / Mildura / Syd) and it was an absolute dream on the Hume and Sturt Hwy's. 120km/h is 2,250, whereas in the R36 it would be 3,000. I don't see any need for this given the torgue of the engine combined with the ease of dropping the DSG back to 5th for even more rapid overtaking.

Not that it makes too much difference, but to be specific the R36 (wagon) is at 2400 rpm is 6th at 100kmh. I'd assume the sedan is geared the same.
