About Proton Exora

The Proton Exora is a compact MPV vehicle produced by Malaysia car manufacturer Proton and launched on 15 April 2009. It is a new model from Proton based on a new chassis. The development of this MPV started from scratch and it is the first Malaysian-designed MPV. Fully undisguised photos of Proton Exora were leaked onto the Internet on the 23rd of January 2009, ahead of the MPV's April 2009 launch date.

Performance

The Proton Exora chassis uses a MacPherson strut design at the front and a torsion beam at the rear. It measures 4,592 mm (180.8 in) long, 1,809 mm (71.2 in) wide and 1,691 mm (66.6 in) tall with a wheelbase of 2,730 mm (107.5 in). It is powered by the Cam pro CPS engine producing 125 hp (93 kW) and 150 N·m (110 lb·ft) of torque, resulting the top speed of165 km/h (103 mph).

The average fuel consumption of 7.2 L/100 km (39 mpg-imp; 33 mpg-US). The gearbox is similar to the Proton Waja and Proton Gen-2 but has a higher final drive ratio to help with power delivery.

The Exora features a Body Control Module which allows automatic activation and configuration of various vehicle functions such as door locking/unlocking, interior lamps, headlamps, brake lamps, hazard lights and wipers.

About Proton Saga

The Proton Saga is a subcompact car, formerly a compact car manufactured by Malaysian auto manufacturer Proton since September 1985. The name "Saga" was chosen from the winner of the contest which was held to choose the first car's name, Ismail Jaafar,[1] a retired military soldier. This name was derived from "saga" (Abrus precatorius), which is a type of soft, fragile, oily, highly combustible but productive seed commonly found in Malaysia, and incidentally, the Proton Saga 1.3 litre engine "is as strong as the saga seed".

The Saga and its variants contribute to most of Proton's sales and revenues since its introduction. For nearly 22 years, the first-generation Saga is the longest surviving Proton model to date, ahead of its mid size car, the Proton Perdana. The original Saga model was originally based on the 1983 Mitsubishi Lancer Fiore to avoid R&D costs, and retained it throughout its production lifespan. In 2008, a long overdue successor designed in-house by Proton was launched to conceal the aging platform. In August of that year, the 3 millionth car produced by Proton was a second generation Proton Saga.

Engine and Performance

The new Saga is powered by the same 1.3-litre Cam pro engine (which was co-designed with Lotus) that is fitted to entry-level Gen-2s. Like other Proton models powered by Proton's own Cam pro engines, the 1.3-liter engine is rated at 94 hp (70 kW; 95 PS) at 6,000 rpm and 120 N·m (89 lb·ft) at 4,000 rpm.[5] The engines feature the new Integrated Air-Fuel Module (IAFM) which varies the airflow into the engine to improve efficiency, smartening out the problematic dip in the torque curve in the lower and middle rev ranges. The ignition system has also been updated with coil-on-plugs instead of the traditional ignition cable system, eliminating power loss. Compared to the (non-IAFM) 1.3-litre in the Satria Neo, power delivery characteristics are remarkably different. Noticeable torque is felt after 2,500 rpm all the way to 4,000 rpm.[5] The acceleration to highway speeds is good. The 5-speed manual from Aichi Kikai is not geared towards the ultimate refinement at cruising speeds, but it does offer a good spread of torque everywhere, not to mention good overtaking power anywhere from 80-120 km/h.[5] Suspension setup consists of MacPherson struts and a stabilizer bar up front with a torsion beam in the rear. Its Lotus designed torsion beam suspension enables it to turn in sharply and hold its stance through corners without much under steering.[5] Fuel economy is even better, approximately 6 L/100 km (47 mpg-imp; 39 mpg-US) for the manual transmission.[5]

Besides the 1.3L engine option, the 1.6-liter Cam pro version is also available as an exclusive engine option for taxi operators. It also features IAFM and produces 114 hp (85 kW; 116 PS) at 6,500 rpm and 148 N·m (109 lb·ft) at 4,000 rpm. Top-of-the-line versions (currently the M-Line) are fitted with a set of 14-inch rims and 185/65 R14 tyres for added traction, providing the car with strong braking force and better road holding. However, the car is not equipped with ABS.

About Proton Gen 2

The Proton Gen-2 is an automobile manufactured by Malaysian car maker Proton, and was launched in the third quarter of 2004. The Gen-2 uses a platform which has been extensively developed in-house by Proton and their partner Lotus. Initially codenamed the Proton Wira Replacement Model, it was hinted that the car was to replace the Proton Wira. The name Gen-2 is an abbreviation of Generation 2, to symbolized the second generation of the very successful Wira as the first generation.

The Gen-2 was among the first cars to be produced in Proton's Tanjung Malim plant, developed as part of its Proton City development project.

The Gen-2's platform is also used by the Proton Satria Neo (with a shortened wheelbase) and the Proton Persona (with an extended rear hang to form a more sedan-like body).

Performance

Proton owns Lotus Cars which was involved in the development of the car. The Gen-2 is the first Proton model to use the new Proton/Lotus developed Cam pro engine. Although the Gen-2's S4PH 1.6 Litre engine delivers a claimed 0–100 km/h time of 11.2 seconds (manual transmission) and a contemporary maximum power output of 110 PS (81 kW; 108 hp) at 6000 rpm, it suffers from poor mid-range torque.

This is due to a torque dip in the crucial 2,000 to 3,000 rpm operating range, where the torque output decreases slightly before picking up back to its peak torque, which is delivered at 4,000 rpm. This torque characteristic can clearly be seen in manufacturer published engine performance curves and is widely attributed to the missing Camshaft Profiling System (CPS) technical feature that the engine was named after, but which did not make production, to save costs. The original (non-CPS) Gen-2's Ecu's Engine and Automatic Transmission mapping has been modified several times since the car's launch to improve perceived mid-range pick-up, but the upgrades did not markedly improve the cars drive ability.

This undesirable torque dip was eventually corrected by Proton in 2008 with the introduction of the "new" Cam pro engine, designated Cam pro CPS, which finally delivered camshaft profiling (variable valve timing) as part of the engine specification.

About Proton Waja

The Proton Waja is a saloon car designed in-house by Malaysian automotive company, Proton, first released in August 2000. The Waja is the first Malaysian-designed car. The name Waja, which means "tough (as steel)", reflects the strength of the steel used for the Waja compared with the previous models. The name was chosen partly to counter the perception in the domestic market that Proton cars were less strong.[citation needed] In the United Kingdom, the Waja is sold as Proton Impian, "Impian" being another derivative of the Malay language, meaning "dream".

Performance

In its initial years in the market, the Waja was originally powered by a Mitsubishi 4G18 SOHC 1.6 L engine. Also made standard since the introduction of the Waja are multi-point fuel injection and brake configuration (front ventilated disc brakes and rear disc brake). All Wajas (excluding the Waja Chancellor) are also available in both manual (5 speed) or automatic transmissions (4 speed).

In 2002, the 1.8 L variant was introduced, powered by the same engine used in Renault Laguna II. The 1.8 L model incorporated drive-by-wire technology and variable valve timing (VVT) technology. However, the 1.8 L model suffered from poor sales because Malaysian customers were more familiar with Japanese engines and were less confident with European engines. As a result, the 1.8 L variant was phased out in the following year.

By January 2006, the Cam pro engine was finally used to power the Waja. Although the engine is similar to the engine used in the Proton Gen-2, the DOHC Cam pro engine used in the Waja has higher power and torque, probably due to the remapping of the ECU and also a different air intake system. The 2008 Proton Waja is now powered with a Cam pro CPS engine with variable valve timing, which was not available in the previous Waja Cam pro models.

The Waja Chancellor, which launched 2006, featured a longer wheelbase and was powered by a Mitsubishi 6A12 2.0 L V6 engine similar to that used in Proton Perdana V6, also sourced from Mitsubishi. The car is also available only with a 4-speed automatic transmission.
