Grandis is equipped with a 2.4L naturally aspirated engine across all models, which is an MPV vehicle. The 2.4L naturally aspirated engine in the Mitsubishi Grandis delivers 130 horsepower and a maximum torque of 205 Nm. This engine can output its maximum power at 5000 rpm and reach peak torque at 3000 rpm. The engine features multi-point fuel injection technology and utilizes an aluminum cylinder head with a cast iron cylinder block. Below is an introduction to the Mitsubishi Grandis: 1. The 2.4L naturally aspirated engine in the Mitsubishi Grandis employs relatively mature technology, offering good reliability and durability. The only drawback of this engine is its somewhat high fuel consumption, especially in models equipped with a 4AT transmission, which tend to consume even more fuel. The engine is paired with either a 5-speed manual transmission or a 4AT transmission. The AT transmission offers better reliability and durability, along with smoother gear shifting. 2. The Mitsubishi Grandis uses a MacPherson independent suspension at the front and a semi-trailing arm independent suspension at the rear. The interior space of the Mitsubishi Grandis is also quite spacious, with the vehicle's dimensions being 4705 mm in length, 1780 mm in width, 1650 mm in height, and a wheelbase of 2776 mm.

I recently researched the specs of the old Space Wagon. When it was domestically produced around 2005, it mainly used Mitsubishi's classic 4G64 engine - a 2.4L inline-four. This engine is quite mature in technology, rugged and durable, though its fuel consumption is considered high by today's standards. Many domestic MPVs back then used this powertrain, with maximum horsepower around 130, paired with either a 5-speed manual or 4-speed automatic transmission. Honestly, most units seen in the second-hand market today still have this engine - you can spot Mitsubishi's signature red ignition coils under the hood. However, the imported first-gen Space Wagon used a 1.8L 4G63 engine, which is rarely seen in China.

My neighbor is still driving a 2007 Grandis, and every time we talk about cars, he says it's like an old workhorse. That 4G64 engine may accelerate slowly, but it has never left him stranded. Once I saw him open the hood for maintenance, and the layout was so tidy that changing spark plugs didn't require removing too many parts. Although this cast-iron engine is technologically outdated, repairs are genuinely cheap, and aftermarket parts are everywhere. In the city, it consumes at least 12 liters per 100 kilometers, but on the highway, it can drop to 8. He says the most annoying part is the engine's roar when overtaking with the AC on, as its 140 Nm torque can't even compete with a small Honda Fit nowadays.

The Grandis commonly found in the used car market is mostly the silver 2.4L version, and under the hood you'll almost certainly find the 4G64 engine. This engine has two defining characteristics: durability. Back in the day, Mitsubishi fitted this engine into over a dozen models, from the Grandis to the Delica and even the Leopard Black King. The valves are quite noisy during cold starts but quiet down once warmed up, with a common issue being oil leaks from the valve cover gasket. While its technical specs seem ordinary by today's standards, its main advantage is low repair difficulty—even roadside mechanics can fix it blindfolded. Idle vibration becomes noticeable when the engine mounts age, but replacing them with OEM parts costs just a couple hundred yuan.

A blue-smoking Grandis came into the repair shop, clearly showing the classic oil-burning symptoms of the 4G64 engine. This engine is particularly interesting in the Grandis: it delivers decent low-end torque but gets excessively noisy above 3000 rpm. The flawed piston ring design leads to widespread oil consumption after 100,000 km, but replacing it with an improved piston ring set can last five to six years. Experienced drivers know this engine requires frequent oil changes with 30-weight oil, and the factory cooling system is prone to scaling, so it's best to flush the radiator every two years. Although its power specs are far behind modern 1.5T engines, the chassis weight distribution is well-executed, showing minimal power degradation even when fully loaded.

I remember an experienced auto repair master once said that when evaluating an old car, you should check the tidiness of the engine bay. The 4G64 engine in the Grandis is a perfect example: the intake piping snakes around half the engine compartment, with the ignition coils prominently positioned right in the center. What's most amazing about this engine is its exceptional compatibility—I've seen conversions to natural gas, ethanol blends, and even installations of supercharger kits. In stock configuration, its low-end torque outperforms the GL8 from the same era, though fuel efficiency isn't its strong suit. A common issue is the crankshaft position sensor frequently triggering fault codes, but replacement parts are 30% cheaper than Volkswagen's equivalents from that period. Occasionally, you can still spot Grandis models modified with VIP styling, but pop the hood and you'll find the same honest red-headed Mitsubishi engine underneath.
