Lexus vehicles have again been recognised for their security by coming top in the What Car? Security Supertest for the fifth year in a row.

The LS430, having won for the fourth consecutive time, was joined by the SC430 at the top of the charts, both having recorded a 100% perfect score in the security tests.

A variety of tests were conducted, aimed at reproducing the techniques used by professional car criminals.

The Lexus RX narrowly missed out on recording yet another perfect score.  As with all 4x4s and hatchbacks, the RX’s folding rear seats preclude the possibility of implementing a secure bulkhead between the boot and passenger compartment, meaning only a maximum score of 95% could be achieved.

The Lexus LS boasts convenience as well as security, with its intelligent keyless locking system that only unlocks the driver’s door, minimising the possibility of an attack by a thief lurking nearby.

The SC430, as with the LS430, boasts various security-marked parts, a visible VIN, dead-locking and security window etching as standard.
