Why Automakers are Switching to Smaller, Turbo Engines for Better MPG

Automakers are constantly looking for ways to improve fuel efficiency without sacrificing power and performance. One way they are achieving this is through the rise of turbo engines. In the past, smaller four-cylinder engines were typically found in economy cars, while larger six-cylinder engines were reserved for higher-end vehicles. However, advancements in technology have allowed automakers to create turbocharged engines that offer both fuel efficiency and power. This trend is evident in the latest compact SUV road tests, where turbo engines are becoming more common even in higher-priced vehicles.

As fuel efficiency becomes a top priority for automakers, many are turning to turbo engines to improve their vehicles' gas mileage. Even luxury car brands are now using four-cylinder engines in their larger models, thanks to the use of turbochargers. These engines can produce the same power as larger engines, but with the fuel economy of a smaller one, making them an attractive option for drivers looking to save money at the pump.

SUVs like the Audi Q5 and BMW X3 now feature four-cylinder engines that are more refined than ever before. Modern turbos are also more reliable and responsive, with significantly less "turbo lag" when you hit the gas pedal. These advancements in turbo technology have allowed for greater fuel efficiency without sacrificing performance.

The Ford Edge now offers a four-cylinder engine that is not only smoother than its V6 counterpart, but also gets better gas mileage. Similarly, the Mercedes-Benz C250 sedan uses a 1.8-liter turbo four that is incredibly smooth and efficient. As technology continues to advance, we can expect to see even more improvements in fuel efficiency from automakers.

As automakers strive to improve fuel efficiency, turbo engines have become increasingly popular. While these engines can provide better gas mileage, they may not be as smooth as their six-cylinder counterparts. The four-cylinder engines used in models like the X3 and Q5 can emit a buzzing sound and a diesel-like clatter at idle due to their direct injection. Despite these drawbacks, the trend towards turbo engines is likely to continue as car manufacturers seek to meet stricter fuel economy standards.
