The hybrid model of Sonata has taken over regardless of the fact that the automaker’s average-sized sedan was set to be redesigned this year. An all-new Sonata hybrid will be released in 2016 and for even better fuel efficiency; a new plug-in hybrid version will be designed. The regular hybrid model was used to test for the efficiency of car sets. This hybrid model earns straight-A-grades, thanks to its open latch anchors and ample legroom. The car’s second row is fitted with two car seats.

What is liked about the car are the two latch anchor sets that have an easy usability. There are plastic covers located on top of these anchors and accessing them necessitates pushing back with the Latch. There is enough room for the back infant seat as well as convertible seats. To accommodate either child seat, there is no need to push forward the passenger seat. On the rear shelf, there are tether anchors that are not only clearly marked but also accessible. The convertible’s tether strap at the top can be connected easily without difficulties. The fitting of the booster on the somewhat curved seat is perfect. To make it easy for young ones to fasten up on their own, there are buckles with stable bases.

With respect to the grading scale, a model gets the highest grade for having enough room for both the child and car seats. The front-passenger or driver legroom is not affected. Additionally, finding and connecting to tether and latch anchors is extremely easy. Issues associated with seat contouring or head restraint are few to none. A car model gets a B-grade when it has plenty of space with a one or two issues related to fitting or connection. There may also be issues regarding gaining access to the third row. A C-grade is given to a model for its marginal room and difficulty in getting to other rows. A D-grade refers to insufficient room while an F-grade is awarded when the seats are unsafe and do not fit.
