Powertrain and Mechanical

• Variable valve control allows the lift, duration and/or timing of the intake or exhaust valves to be altered while the engine is in operation.

Safety and Security

• Brake assist senses panic braking from the speed of the brake pedal's travel and applies all available power brake boost.
• Ignition immobilizer is a passive means of security. It consists of a transmitter embedded within the ignition key and a sensor located in the vehicle. These two circuits must be present, and must recognize each other before the vehicle will start.
• The instrument cluster gauges are traditional analog style as well as digital numeric readout.
• Electronic stability control monitors and compares vehicle dynamics to driver input (steering/braking/speed). When oversteer (fishtailing) or understeer (plowing) is detected, the computerized system engages the traction control and anti-lock brake systems in an attempt to control skidding.
