In Canada, they are on the record confirming that the SR will not have access to a software unlock to upgrade. This may be to discourage it’s purchase, or to ensure compliance with Canadian federal incentive rules. Nobody is really sure at this point. The Canadian version of the SR has and even shorter range, and sells for a little less.If I buy an Sr now can you pay to have it upgraded to an SR+ later? Since it appears to be the same car?
