The Mitsubishi 4G92 112 PS (110 hp/82 kW) 1.6L 16-valve SOHC engine with multi-point fuel injection was introduced together with an optional 4-speed automatic transmission automatic transmission (and power windows for all 4 doors), a first in Proton's history. The multi-point injection versions were badged as MPi, although this was only used on the engine, and never on the trim levels (unlike 1.5 MPi GLS in the previous car, the Saga, the trim levels were simply 1.5 GLS etc.).
[1] In 1995, the Mitsubishi 4G13 1.3-litre 12-valve engine also used in the Saga was introduced for the Wira. This was followed in 1996 by the 133 bhp (99 kW) 1.8L 16-valve DOHC DOHC engine with multi-point fuel injection, marking a first in which a Proton car was powered by a DOHC engine.
[1] As with the Saga, all export models used multi-point fuel injection to comply with the Euro I emissions standards.

The V6 was refitted with a throttle-body fuel injection system for 1986 in order to improve performance and fuel economy. [2] The idea behind was rather straightforward - take a basic-transportation economy car and give it a high-performance package, making it practical and sporty. It was one of the first small cars to adopt mechanical fuel injection for its sports version, which raised power output of the 1588 cc engine to 110 PS PS (81 kW/108 hp).
[3] The British UKDM 1.8 GL was equipped initially with a carburetor and rear drum brakes but were later upgraded to fuel injection and rear disc brakes.
[4] The 2.0 liter and 2.2 liter engines fuel delivery were managed with sequential multiport fuel injection called MPFI, and the 1.8 liter engine used a modified fuel delivery system with single point fuel injection called SPFI.
[4] Under the hood went an Oldsmobile -sourced 350 in" (5.7L) V8, fitted with Bendix / Bosch electronically controlled fuel injection. This system gave the Seville smooth drivability and performance that was usually lacking in other domestic cars of this early emissions control era.
[5] For 1989, the 5.9 L V8 also received throttle body fuel injection for 20 hp (15 kW) more power.
[6] Although the throttle body fuel injection system worked relatively well, it was primitive and replaced after only 4 years of use.
[6] The engines were substantially upgraded for 1992 (3.9L and 5.2L) and 1993 (5.9) with multiport fuel injection, new manifolds and higher compression cylinder heads for noticeably higher output.
[6] High performance 5 Series - 24-valve DOHC DOHC, I6, six throttle bodies, Bosch Motronic integrated fuel injection. At its launch in 1984, the European specification E28 M5 was the fastest production sedan in the world.
[7] In 1986 and 1987, the engines were switched from carburetors to electronic fuel injection.
[8] The system that GM chose was called throttle body injection, or TBI. The change improved fuel economy, performance, and emissions.
