Subaru has taken a significant step up with its new turbocharged BRZ rally car, the Boxer Rally Spec.Z. By borrowing the WRX's turbo boxer engine, it has given the road-going BRZ a major hardware boost. The result is a purpose-built competition animal that will compete in the Japanese Rally Championship starting this May.
The rally car features a custom bodykit, including a redesigned front bumper and a vented hood, as well as lexan windows and a racing livery. Its interior has been stripped out to meet FIA-compliant roll cage standards.
While the rally spec looks cool, the highlight is what lies under the hood. The turbocharged 2.4-liter Boxer engine produces over 276 hp and 500 Nm of torque, significantly more than the naturally-aspirated mill of the production BRZ.
The powertrain has been tuned to send power to all four wheels via a six-speed sequential transmission, giving it an edge in tackling grueling stages. This direct-drive AWD system allows it to compete with other rally cars alongside its overhauled chassis setup.
Subaru engineers claim they have achieved a balance between sharp cornering performance and high-speed stability. The model rides on 18-inch Work aluminum wheels shod in Advan tires, with braking handled by four-piston calipers.
Weight is critical here as well, with the minimum weight requirement under JP4 regulations sitting at 1,300 kg (2,866 lbs). The BRZ slips beneath this figure, giving Subaru room to fine-tune ballast placement and chase a more favorable weight distribution.
This move highlights Subaru's commitment to motorsports, but its limited production potential may disappoint enthusiasts. Nevertheless, the Boxer Rally Spec.Z represents a significant step up for the brand in rally competition.
The BRZ has been reworked into an AWD weapon, giving it a hardware boost that will be put to the test in the JRC starting this May.
With its turbocharged engine and direct-drive AWD system, the Boxer Rally Spec.Z is well-equipped to tackle the challenges of Japanese rally competition.
