About this engine family

The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads. The engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain, and a cast aluminium lower intake manifold. Some variants use multi-port fuel injection, some have D4 direct injection, and others have a combination of direct injection and multi-port fuel injection or D4-S.

In detail

The 1GR-FE is the version, designed for longitudinal mounting in RWD and 4WD pickup applications. It has a bore and a stroke of . Output is at 5200 rpm with of torque at 4000 rpm when tuned for 87 octane, and at 5200 rpm with at 3700 rpm when tuned for 91 octane. This engine features Toyota's VVT-i, variable valve timing system on the intake cam and a compression ratio of 10.0:1. Service weight, including fluids, is .

An updated version of this engine features Dual VVT-i, increasing output to at 5600 rpm and at 4400 rpm on 87 octane. Inside, the 1GR uses a "taper-squish" combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls.

This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. In the event of cylinder wall damage (scoring, deep protrusions, etc.), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines.

For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are two such passages for each bank for a total of four. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform. A bolt-on TRD supercharger kit was available on the Tacoma and FJ Cruiser but has been discontinued by Toyota. The new 2015 Toyota HiLux receives a slightly different version of the single VVT-i engine, with the only change being a removal of an air intake baffle tank being replaced by a conventional air filter housing to intake pipe to surge tank style.

The new intake pipe now contains resonators. Power output is unchanged. First generation 1GR-FE variants with single VVT-i features Toyota's Acoustic Control Induction System. This system consists of a bulkhead to divide the intake manifold into two sections, and an intake air control valve (in the bulkhead) to control its effective length. When the engine is operating at moderate revolutions and under high load, an actuator closes the intake air control valve to increase the effective length of the intake manifold.

At other operating conditions, the intake air control valve opens up to reduce the effective length of the intake manifold.

Bore remains; but stroke is reduced. Reported output varies depending on the vehicle application, but is approximately to at 6200 rpm with to of torque at 4700 rpm on 87 octane (R+M/2). This version features Toyota's Dual VVT-i, variable valve timing on both the intake and exhaust cams. The cams are driven using a timing chain.
