 There is a reason why the hybrid cost the same to buy as a non- hybrid would have been.  I had expected the get mileage in the low 40s or high 30s  but we have never had a tank full over 32 mpg.  I have read a lot of complaints about braking drive-ability but haven't found any but poor mileage instead.  As an engineer, I appreciate the difficulty of smoothly integrating electric and mechanical braking and apparently Hyundai has not solved the problem.  They seem to have avoided problems by mostly disabling regenerative braking by keeping the battery mostly charged at high speeds so the regenerative breaking is limited by the lack of available energy storage capacity.   The result is a system that minimizes law suits and warranty battery replacements.  Great for Hyundai to meet government hybrid requirements but I feel used and unlikely to buy another Hyundai - certainly not another hybrid until I am sure they have solved the engineering problems.
