Lotus L5 uses a 1.5L version of the engine, the engine model is 4G93M. The actual displacement of the 4G93M engine is 1834ml, with a total of 4 cylinders, arranged in an L shape, and the intake method is naturally aspirated. The cylinder diameter of this engine is 81mm, the stroke is 89mm, the compression ratio is 10.5, and the valve mechanism is DOHC. The Lotus L5 is a B-class model under Lotus Cars, with body dimensions of 4640mm in length, 1750mm in width, and 1466mm in height, a wheelbase of 2670mm, a front track of 1475mm, and a rear track of 1470mm. The engine equipped in this car has a maximum power of 110kw and a maximum torque of 171nm.
As someone who enjoys studying automotive details, I have to talk about the Lotus L5's engine. It uses a 1.6-liter naturally aspirated engine, which is essentially derived from the Mitsubishi 4G series, commonly the 4G18 or 4G93 models. This engine delivers approximately 120 horsepower and around 150 Nm of torque, paired with either a five-speed manual or a four-speed automatic transmission. It drives quite smoothly, with a 0-100 km/h acceleration time of about 12 seconds. Technically, it features a simple and reliable design, utilizing an aluminum alloy block to reduce weight and incorporating multi-point fuel injection technology for decent fuel efficiency. City driving consumes about 7-8 liters per 100 km, while highway driving drops to around 6 liters. Maintenance is also convenient, with common parts like spark plugs and belts being widely available, making DIY replacements cost-effective. Overall, this engine is well-suited for daily commuting with low failure rates, though older models might feel slightly underpowered when running the AC in summer. Remember to change the engine oil and air filter regularly during maintenance.
When we first bought the Lotus L5, I drove it to work every day. It had a 1.6-liter engine, which I heard was backed by Mitsubishi technology. The acceleration wasn't particularly strong but it was smooth and steady, rarely shaking violently. Over time, I found its fuel consumption quite reasonable, averaging around 7 liters, and reaching up to 8.5 liters in heavy traffic, which wasn't excessive. The most hassle-free part was the simple daily maintenance. For example, when I took it to the repair shop to change the spark plugs, the mechanic praised its classic structure for being reliable and its parts for being inexpensive. During hot summer days, the engine fan noise was a bit louder, but turning on the air conditioning helped. For the average car owner, this engine's performance is sufficient without being flashy. If you're considering a second-hand L5, focus on checking the engine's starting condition and regular maintenance records to ensure there are no oil leaks.
Speaking of the Lotus brand, the L5 was actually developed based on a platform co-developed with the UK, so it used a Mitsubishi 1.6-liter four-cylinder engine, with models like the 4G18 being standard configurations. This powertrain originated from technology sharing in the 1980s and 1990s, aimed at reducing costs and maintaining reliability. As an old car enthusiast, I've read many reports stating that Mitsubishi engines were quite popular in the Chinese market, known for their high durability, and Lotus's choice was a play on cost-effectiveness. Its historical background made it easy for mass production, though the downside was the lack of new technologies, such as turbocharging, but it provided comfortable daily driving.
