In September 1989 Honda also added the 1595 cc B16A VTEC engine to the lineup outside of America.
The VTEC engine used Variable Valve Timing to provide increased power in the high rev range, while still allowing low fuel consumption and better idling at low RPMs.
The B16A produced 150 bhp (112 kW; 152 PS) in the European 1.6i-VT model (where the engine bore the designation B16A1) and 157 bhp (117 kW; 159 PS) in the JDM SiR model.
The CRX was the second car to receive a VTEC engine, shortly after the Integra, although the CRX was more popular and common.
The VTEC-equipped models also received a makeover, with updated bumpers, lights, bonnet/hood, brakes, suspension and dashboard design amongst other things. Additionally, some of these design changes were added to the concurrent non-VTEC models.
