Haven't seen under the hood PP. So can't say for sure. Capacity listed as 2850 cc if that's indicative?
In regard to the wet weather performance what brand / model / section of tyres does the 328 have? I've got a 308 with original 16's and am headed toward new rear tyres soon, any info greatly appreciated.
Bridgestone Potenza S-03 are on it. They were put on by the previous owner. Whilst I'm quite happy with them, I'm not saying that's what I'll be putting on next time. Things have moved on with tyre technology in the 3 years since they were put on.
