Have only had my CX-3 for about 6 weeks, and still enjoy driving it - especially as the weather is improving a bit. Having come from the Rover Tourer with the 2 litre TD4 diesel, I was a little surprised at the turbo lag on acceleration. It is only slight, possibly half a second, until the revs reach about 1800 rpm, when the turbo takes over and the performance is great. I have got used to it now, and try to use a lower gear to keep the revs above 2000 if I want to press on a bit, but I am still surprised. Does anyone know if the very low compression ratio might be a cause? I also read that the update in May 2017 (just after mine was built) had a modification to reduce turbo lag. Is this true? If so, is it a software update that can be retrofitted.
Despite these comments, I do not regret buying the CX-3 in the slightest. So far, I have only seen a few others on the road, but one local one I see quite often, and we now wave to each other - just like having an unusual car in the old days !!
Thanks for this forum, it is very informative, and makes interesting reading.

I thought the point of the Mazda engine design was that it didn't have a turbo?

Oh, never had one. I assume all diesels have turbo's then.santa wrote: ↑Sun Apr 08, 2018 3:22 pmHis CX-3 is a dieselalanandlyn wrote: ↑Sun Apr 08, 2018 3:19 pm I thought the point of the Mazda engine design was that it didn't have a turbo?

Pretty much, I can't think of a diesel without a turbo these days.alanandlyn wrote: ↑Wed Apr 11, 2018 3:06 pmOh, never had one.

But You're correct that Mazda are using non-turbo petrol engines, in contrast to virtually everybody else.

My CX-3 went in last week for the first year service, and I discussed with the dealer (Furrows of Shrewsbury) my concern about the 'turbo lag'. By then I had decided that it was not true turbo lag, but lack of boost at low speeds ( which happened twice on my Rover 75 when the mass air flow meter failed - a common fault on 75s). They agreed that it would be looked at (under warranty) while it was being serviced. It was discovered that it was not a faulty MAF, but a software problem, which took quite a while to fix because a software update takes more than an hour to carry out, and the first download failed. However, it is now fixed, and as well as a better response at low speeds, the average fuel consumption (diesel) on my typical mix of local and longer runs has increased from about 42 MPG to 48, so I am happy.
This information might be of use to other diesel CX-3 users. although I forgot to ask what the previous software version was, but was obviously what was installed in May 2017 when the car was first registered.

Bob,
I had the same view as you when I got the CX-3 and coming from a CX-5 which had no noticeable turbo lag it was quite a surprise viewtopic.php?f=7&t=1227 I discussed it with the dealer last year and they said it was normal after taking it for a test drive.
My CX-3 has gone in for it's 1st year service today and they did mention something about a recall related to engine software. I will try and find out exactly what they have done when I pick it up, but hopefully this will be the same update as yours had.
The CX-3 2018 model I have as a courtesy car doesn't seem quite as bad but the lag is still there.
