SRVD helps the driver to change lanes on the motorway safely or detect hard to see hazards when completing low speed manoeuvres. SRVD is a radar-based system, with radars fitted beneath the Impreza’s tail lamps and covered by the rear bumper, detecting vehicles to either side of the car.
SRVD is a package of three technologies, designed to alert the driver to potential hazards behind the vehicle:
In addition, Impreza is also fitted with high beam assist and steering responsive headlights.
Boxer engines are integral to what makes a Subaru a Subaru, the engine takes its name from the punch-counterpunch motion of the horizontal pistons within a lightweight, aluminium-alloy engine block.
Using a Boxer engine means that the engine can be positioned in line with the drivetrain for maximum transfer of power. Many other engines are transverse or perpendicular, which can require additional drivetrain components to transfer power, which results in reduced vehicle efficiency when compared to a Boxer engine.
The punch-counterpunch movements of the pistons balance each other out, which means the engine is smoother with reduced vibrations and noise. Additionally, the unit provides a lower centre of gravity and in turn, exquisite handling and poise plus greatly reduced roll when cornering.
At launch in the UK, a 1.6 litre engine will be available with a 2.0 litre joining the range after launch.
The 1.6 engine is from the FB series, and is port injected. 70% of the components in the engine have been redesigned.
The compression ratio has been increased from 10.5:1 to 11.0:1, the overall engine weight has been reduced by 14kgs, with the following specific weight savings;
Rotational inertia has been reduced by 6%, vibration reduced by 5% and torsional rigidity has been improved by 10%. Gas flow into the combustion chamber has also been improved.
The series of revisions have ensured that vibration and noise are significantly reduced, and acceleration response has been improved for a more linear feel, making the 1.6 feel more refined all-around.
The 2.0 is also from the FB series of engines, and is direct injected. 80% of the engine has been redesigned, including a 12kg weight reduction.
The compression ratio has been increased from 10.5:1 to 12.5:1, and a new tumble generation valve and port internal baffle has been fitted to the intake which revises air flow in the intake, increasing airflow into the cylinder in order achieve a better mixture and improved fuel efficiency. Another result of development has led to the highest brake thermal efficiency in its class.
The rigidity of the engine block has been increased, and additional mounting points help to minimise vibrations and reduce noise across various engine operating ranges. In addition, this adds to a more consistent feel between acceleration performance and the engine noise.

Lineartronic is the first Continuously Variable Transmission (CVT) adopted for AWD use. Lineartronic has been designed specifically for use with Boxer engines and Symmetrical All-Wheel Drive to optimise fuel consumption via a stepless gear ratio and optimal power band. Lineartronic also has a damper to reduce torque fluctuations, removing the “surge” traditionally associated with CVT gearboxes.
For Impreza, the ratio coverage has been widened and the weight of the transmission has been reduced by 7.8kgs versus the outgoing car. This increases acceleration performance and fuel efficiency.
