The MR2's suspension and handling were designed by Toyota with the help of Lotus engineer Roger Becker. Toyota's cooperation with Lotus during the prototype phase can be seen in the AW11, and it owes much to Lotus's sports cars of the 1960s and 1970s. Toyota's active suspension technology, called TEMS, was not installed. With five structural bulkheads, the MR2 was quite heavy for a two-seater of its size.
