Have regen settings been changed?

Same tires & tp?

 

How can both '11 and '12 be 10th anniversary?​

 

I think you may have bought new old stock there Will. The 10th Anniversary model was supposed to be a limited run manufactured in 2010.
My 2010 T-spirit has no difference in feel between regen and friction braking and I can quite easily back off the pedal to the point of no indication on the HSD.

 

I think they've changed the settings a number of times over the years. I have noticed about 3 software update changes since I got my gen3 new in late 2009. The last one was last October where regen seems much less aggressive and the car seems to use the friction brakes more often and for longer. The ever so slight hesitation in brakes over wet drain covers has now completely gone, compared to how the car was when new.

 

All the 10th's were built at the same time (more or less), all sat on forecourts/storage, DVLA reg date is only when they decided to put it on the road

 

So in your neck of woods, the reg date dictates the model year?

I had a 2002 MY Camry that was built in 9/2001, but purchased and registered in 1/2003. It was still a 2002.

 

I bought my 2010 in Aug of 2009 (build date 7/09) and it does not display the behavior you describe in your 2011. It is very easy to coast using either the HSI (no indication) or my ScanGauge (close to 0 Amps in and out of the battery). The brakes have a gentle transition between regen and friction and if you aren't looking for it you may miss it. As to the brakes I should add that I never had the brake recall that applied to 2010 cars done. This recall reprogrammed the brake ECU to change the brake pedal feel and I like them the way they are.

Will, could your 2011 have had some problems?

 

The date the car was registered is pretty much of utmost importance and the model year less so. The registration/licence plate shows the year coded in so people can tell if you have a new car etc. In fact people very rarely refer to the model year in the way you do your side of the pond. Amusing to us that you all refer to a 2010 Prius which was released in May 2009. A what point can a 2014 model be sold? Feb 2013?

When a new model comes out such as the gen3 Prius update, then the old shape are sold off cheap, often pre-registered by the manufacturer with nominal miles, though because of this are sold second hand. You can find some cracking second hand cars like this, often showing less than 10 miles for £thousands off.

 

Check your VIN number, the 8th digit should be a "U" for Prius, the 9th is probably a "9" and the 10th digit is the year of manufacture, "0" is 2010, "1" is 2011, "2" is 2012 etc.
