Review: Subaru Z1 BRZ (2012-16)

Overview

Released in July 2012, the Subaru Z1 BRZ was a two door coupe with two-plus-two seating. Jointly developed with Toyota and closely related to the Toyota 86 , the rear-wheel drive Subaru BRZ was powered by a 2.0-litre horizontally-opposed (or boxer) engine that was mated to either a six-speed automatic or manual transmission. The Subaru BRZ was manufactured at Subaru’s factory in Gunma, Japan.

Compared to the Toyota 86 , the Subaru BRZ could be identified by its unique front bumper with hexagonal grille, front fender vents and alloy wheel design. The BRZ was also fitted with firmer front suspension springs front suspension and a revised damper tune to limit body roll and reduce oversteer.

FA20D engine

The 2.0-litre FA20D engine had an alloy cylinder block and head, double overhead camshafts, four valves per cylinder, variable valve timing (intake and exhaust) and a compression ratio of 12.5:1. The engine also featured a dual injection system whereby both high-pressure direct-injection and lower-pressure indirect injection would be used at lower engine revolutions for reduced emissions. In high-load situations, however, only direct fuel injection was used.

With the manual and automatic transmissions, the Subaru BRZ could accelerate from rest to 100 km/h in 7.6 and 8.2 seconds, respectively.

Dimensions and body

The Subaru BRZ was 4240 mm long, 1775 mm wide, 1285 mm tall and had a 2570 mm long wheelbase. With the rear seats in position, the Subaru BRZ had a luggage capacity of 218 litres.

With the manual and automatic transmissions, the Subaru BRZ had a kerb mass of 1216 kg and 1238 kg, respectively.

Suspension and steering

The Subaru BRZ had MacPherson strut front suspension with reverse-positioned L-shaped lower-arms (that enabled the engine to be mounted lower and closer to the centre of the vehicle) and double wishbone rear suspension.

The Subaru BRZ had rack-and-pinion steering with electric power-assistance; its turning circle was 10.8 metres.

Safety equipment

Standard safety equipment for the Subaru BRZ included dual front airbags, a driver’s knee airbag, front side airbags, curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control and front seatbelts with pretensioners and load limiters.

Brakes

The Subaru BRZ had ventilated front and rear disc brakes measuring 294 mm by 24 mm at the front and 290 mm by 18 mm at the rear.

Review: Subaru Z1.II BRZ (2016-21)

Overview

Released in Australia in November 2016, the Subaru Z1 Series II (Z1.II) BRZ introduced updated styling, greater power for models with manual transmissions, a more rigid body, revised suspension and an updated interior. Compared to the Subaru Z1 BRZ, the Subaru Z1.II BRZ could be identified by its new LED head- and tail-lights, LED fog and daytime running lights, new front bumper (claimed to provide a wider and lower look), front guard garnish at the base of the A-pillar, new boot garnish and 17-inch ten-spoke alloy wheels. According to Subaru, the new alloy wheel design increases rigidity and control.

FA20D engine

For Subaru Z1.II BRZ models with automatic transmissions, the FA20D engine was unchanged. For Z1.II BRZ models with manual transmissions, however, the FA20D engine benefited from the following revisions which increased peak power and torque to 152 kW and 212 Nm:

• A more rigid cylinder block due to additional stiffening ribs at the rear wall;
• For greater durability, the piston crown surfaces and pin boss sections underwent FSR-K treatment (shot-peening small particles at high speeds to produce a stronger layer on the material surface, due to microscopic plastic deformation);
• The internal shape of rocker arm pivots was revised;
• New intake and exhaust valves with buffed and polished valve stems were introduced;
• A reduced-friction finish for the camshaft journals was applied;
• Fuel pump cam lift was reduced to optimise the fuel pump flow rate (left-hand intake only), while the operating range of the fuel pump was also reduced to minimise friction;
• A new aluminium intake manifold was introduced which optimised the length of the manifold for greater resonance. Furthermore, the air cleaner element, air cleaner box and intake system adopted more streamlined intake air channels that reduced airflow resistance by approximately 30 per cent. To reduce induction noise, the capacity of the air cleaner was increased and both the intake duct and intake boot were revised;
• The diameter of the 4-2-1 exhaust pipe was enlarged for greater exhaust pulse resonance. Specifically, the diameter of each branch was increased from 42.7 mm to 45 mm and from 45 mm to 48.6 mm;
• A new fuel pressure sensor and new fuel pump were introduced; and,
• The ECU was revised.

For the manual transmission, final gear ratio was reduced from 4.1:1 to 4.3:1 for greater acceleration (the final drive for the automatic transmission was unchanged at 4.1:1). According to Subaru, the durability of the six-speed transmission was also increased for the engine’s higher output.

Chassis

For the Subaru Z1.II BRZ, the following changes were made to the chassis:

• A thicker V-shaped strut tower bar mounting bracket (on the middle of the dashboard panel) was fitted for greater rigidity;
• A thicker reinforcing plate for the transmission cross-member was fitted and the cross-member had a revised shape; and,
• The rear wheel housings had additional reinforcement.

Suspension

For the Subaru Z1.II BRZ, the following changes were made to the chassis:

• New front struts and rear shock absorbers with revised damping and reduced friction;
• A new spring constant for the coil springs (front and rear);
• Revised rear stabilisers; and,
• New front differential mount stoppers to reduce vibration and noise.

According to Subaru, these changes were intended to provide greater ride comfort and driving stability.

Safety equipment

While safety equipment for the Subaru Z1.II BRZ was unchanged, the electronic stability control system has a new ‘Track’ mode which, according to Subaru, provided ‘greater stability control for better handling’.

Features

Inside, the Subaru Z1.II BRZ had enhanced instrument gauges, an upgraded infotainment system with a 6.2-inch display, a smaller steering wheel with ‘premium-feel’ leather, new paddle switches, knee pads and red stitching for the instrument panel seams.

From December 2017 (‘model year 2018’), the Subaru Z1.II BRZ was equipped with a ‘third generation’ infotainment system which included a seven-inch touchscreen, satellite navigation and smartphone integration via Apple CarPlay and Android Auto.

Subaru BRZ tS

The Subaru BRZ tS was released in Australia in December 2017. Visually, the BRZ tS could be identified by its 18-inch STI spin-forged aluminium wheels with fifteen spokes and a black finish, unique front bumper with tS badge on the grille, red-painted brake callipers, tS and STI exterior badging, STI side garnish, and black finishes for the rear spoiler, door mirrors and shark-fin antenna. Inside, the BRZ tS featured Alcantara seat trim with tS logo, red interior highlights, unique steering wheel with STI logo, ‘Grand Luxe’ door panel trim and dashboard highlights, red seatbelts and a push-button starter with STI logo.

For greater dynamic ability, the Subaru BRZ tS had the following attributes:

• 215/40 R18 Michelin Pilot Sport 4 tyres;
• Sachs shock absorbers tuned by STI for linear response;
• Coil springs tuned by STI to reduce body roll;
• 326 mm by 30 mm ventilated front brake discs with four-piston Brembo callipers (and 75 cm²brake pads) and 316 mm by 20 mm ventilated rear discs with two-piston Brembo callipers;
• A flexible V-shaped bar between the front suspension towers; and,
• A flexible draw stiffener which linked the front suspension cross member and sub-frame at an angle and applied a pre-load to reduce the delay in chassis movement after steering.
