Ashok Leyland, the Hinduja Group flagship, has sold Defiance Testing & Engineering Services (DTE) to Exova, a provider of testing, calibration, and advisory services. Located near Detroit, DTE was acquired by Ashok Leyland in 2007 and since has experienced consistent and profitable growth, according to the Indian OEM, through a combination of operational efficiency, new customer capture, and focus on adjacent sectors such as construction and off-highway, and defense. Ashok Leyland claims that DTE helped it attain new skills in testing and validation that led to reduced new-product development time and costs. DTE provides testing and engineering services to manufacturers and leading suppliers in the passenger car, light truck, bus, and military vehicle sectors. Its range of capabilities includes component and system testing, fatigue and durability validation, system simulation, and full-vehicle structural testing. Ashok Leyland’s separate entity focused on IT and Engineering Services, Defiance Technologies Ltd., remains unaffected by the transaction.
