Let's dive deep into the heart of the 2017 Mitsubishi Lancer LE: the engine. For car enthusiasts and potential buyers, understanding the engine's specifications and performance is crucial. This article will provide you with a comprehensive overview, ensuring you know everything about what powers this popular compact sedan.

Overview of the 2017 Mitsubishi Lancer LE Engine

The 2017 Mitsubishi Lancer LE is equipped with a 2.0-liter inline-4 engine. This engine is designed to offer a balance of fuel efficiency and adequate power for daily driving. The 2.0-liter engine, part of the 4B11 engine family, features a dual overhead camshaft (DOHC) configuration and a four-valve-per-cylinder design. This setup helps in optimizing both intake and exhaust flow, enhancing the engine's overall performance and efficiency. The engine block and cylinder head are made from aluminum alloy, which contributes to the vehicle's overall weight reduction and improved thermal management. This is a common feature in modern engines, aiding in fuel efficiency and reducing emissions.

This engine delivers a horsepower of 148 at 6,000 rpm and a torque of 145 lb-ft at 4,200 rpm. The power output is well-suited for city driving and typical commuting needs. The engine's torque curve is relatively flat, providing decent acceleration and responsiveness across a wide range of engine speeds. This means you don't have to rev the engine excessively to get the car moving, which is beneficial for fuel economy and driving comfort. The engine also features Mitsubishi's MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) technology, which optimizes valve timing to improve power and efficiency. MIVEC adjusts the intake valve timing according to driving conditions, enhancing engine performance and reducing emissions. This technology helps in achieving a good balance between power, fuel efficiency, and environmental friendliness.

Furthermore, the engine is paired with either a 5-speed manual transmission or a continuously variable transmission (CVT), depending on the specific configuration. The 5-speed manual transmission offers a more engaging driving experience, allowing drivers to have greater control over gear selection. On the other hand, the CVT provides smooth and seamless acceleration, optimizing fuel efficiency by keeping the engine in its most efficient operating range. The CVT is particularly useful in urban driving conditions, where frequent stops and starts can impact fuel economy. Both transmission options are designed to complement the engine's characteristics, offering drivers a choice based on their preferences and driving needs.

Key Engine Specifications

Understanding the detailed specifications of the 2017 Mitsubishi Lancer LE engine can further clarify its capabilities. Let's break down the key specs:

• Engine Type: 2.0-liter Inline-4
• Engine Code: 4B11
• Displacement: 1,998 cc (122 cu in)
• Bore x Stroke: 86.0 mm x 86.0 mm (3.39 in x 3.39 in)
• Compression Ratio: 10.0:1
• Horsepower: 148 hp at 6,000 rpm
• Torque: 145 lb-ft at 4,200 rpm
• Fuel System: Multi-point Fuel Injection
• Valve Train: DOHC, 4 valves per cylinder
• Fuel Type: Regular Unleaded

The engine's square bore and stroke dimensions (86.0 mm x 86.0 mm) indicate a balanced design, where neither the bore nor the stroke is significantly larger than the other. This typically results in a good balance of low-end torque and high-end power. The compression ratio of 10.0:1 is moderate, allowing the engine to run efficiently on regular unleaded fuel without requiring premium fuel. The multi-point fuel injection system ensures precise fuel delivery to each cylinder, optimizing combustion and reducing emissions. The DOHC valve train with four valves per cylinder enhances the engine's breathing capabilities, allowing for better airflow and improved performance.

These specifications collectively contribute to the engine's overall performance, fuel efficiency, and reliability. Knowing these details can help you better understand the engine's capabilities and how it performs in various driving conditions. Whether you're considering purchasing a 2017 Mitsubishi Lancer LE or simply curious about its engine, these specifications provide valuable insights.

Performance and Fuel Efficiency

When evaluating a car, performance and fuel efficiency are often top priorities. The 2017 Mitsubishi Lancer LE strikes a reasonable balance in these areas, making it a practical choice for many drivers. The 2.0-liter engine provides sufficient power for everyday driving, while its fuel efficiency helps keep running costs down.

In terms of performance, the 2017 Lancer LE can accelerate from 0 to 60 mph in approximately 9.0 seconds. While this isn't sports car territory, it's adequate for merging onto highways and navigating city traffic. The engine's torque delivery is smooth and linear, providing responsive acceleration when needed. The availability of both a 5-speed manual transmission and a CVT allows drivers to choose the option that best suits their driving style. The manual transmission offers a more engaging experience, while the CVT provides smoother acceleration and better fuel efficiency.

Regarding fuel efficiency, the 2017 Lancer LE achieves EPA-estimated ratings of 24 mpg in the city and 34 mpg on the highway with the CVT. The manual transmission variant has slightly lower ratings, typically around 24 mpg in the city and 33 mpg on the highway. These figures are competitive for the compact sedan class, making the Lancer LE an economical choice for daily commuting and long trips. Real-world fuel economy can vary depending on driving conditions, habits, and maintenance. However, with careful driving, it's possible to achieve or even exceed the EPA estimates.

Several factors contribute to the Lancer LE's fuel efficiency. The engine's MIVEC technology optimizes valve timing to improve combustion and reduce fuel consumption. The lightweight aluminum engine block and cylinder head help reduce the vehicle's overall weight, which also contributes to better fuel economy. The CVT, in particular, is designed to keep the engine operating at its most efficient speed, maximizing fuel economy. Regular maintenance, such as oil changes and air filter replacements, can also help maintain optimal fuel efficiency.

Common Issues and Maintenance

Like any vehicle, the 2017 Mitsubishi Lancer LE can experience common issues and requires regular maintenance to ensure long-term reliability. Being aware of these potential issues and following a consistent maintenance schedule can help you keep your Lancer LE running smoothly for years to come.

Some of the common issues reported by Lancer LE owners include problems with the CVT, such as shuddering or slipping. These issues can often be addressed with a software update or a fluid change. Other potential problems include issues with the air conditioning system, such as refrigerant leaks or compressor failures. Regular inspection and maintenance of the A/C system can help prevent these issues. Additionally, some owners have reported issues with the car's electrical system, such as battery drain or faulty sensors. Proper diagnosis and repair of electrical issues are essential to prevent further damage.

To ensure the longevity and reliability of your 2017 Lancer LE, it's crucial to follow the manufacturer's recommended maintenance schedule.
