Subaru FA20 / Toyota 4U-GSE Engine

 

One of the most awaited cars of 2012 is the new rear wheel drive sports car developed jointly by Toyota and Subaru. Toyota version is called GT-86 and Subaru version is called BRZ, only for North American market, the car is also sold under Scion brand which will be called FR-S. The car might be marketed under different names but all versions share the same body, chassis, drivetrain and of course, the same engine. 2 liter naturally aspirated four-cylinder engine is named 4U-GSE by Toyota (Scion also uses same engine code) versions and FA20 by Subaru. Just like the rest of the car, the engine is developed from ground up together by Toyota and Subaru.

 

 

4U-GSE / FA20 is a horizontally opposed (boxer) 4 cylinder dual overhead cam engine, displacing 1998cc with square, 86mm by 86mm bore and stroke.  Compression ratio is 12.5:1, a very high value rarely found on a serial production engine. 4U-GSE / FA20 is exclusively designed to incorporate Subaru’s area of expertise, the boxer engine, with Toyota’s outstanding D4-S injection system to deliver increased horsepower and torque without sacrificing fuel efficiency. DS-4 is a system that combines direct injection and port injection. Under high load direct injection is used to deliver better throttle response and high performance. Under low loads the direct and port injection are used together for optimized fuel consumption and low emissions.

 

Subaru FA20 / Toyota 4U-GSE Engine

 

4U-GSE / FA20 utilizes Subaru’s Active Valve Control System (AVCS) on both intake and exhaust cams. AVCS is a variable valve timing technology that uses hydraulic pressure to manipulate the valve timing according to engine load. AVCS analyzes information from camshaft sensors, crankshaft sensors, air flow meter, oxygen sensors and/or Air-Fuel ratio sensors in order to calculate engine load.

 

 

 

With technologies delivered from two leading Japanese automotive manufacturers’ 4U-GSE / FA20 easily delivers 200hp at 7000RPM and 205Nm torque at 3000RPM. The redline is set at 7450RPM. 4U-GSE / FA20 might be new in the game. But is easy to say that it will be one of the most successful engines of its era.
