2.0 Liter Engines Now On The Trend
In the 1960s, big V8s were all the rage. Then V6 engines became very popular. Today, if you're shopping for a new car or SUV, chances are it's going to be powered by a turbocharged 2.0-liter inline four-cylinder engine. 
Small, light and powerful, the turbocharged 2.0-liter has become one of the most common engine configurations used by automakers from the United States, Germany, Italy, Japan, Great Britain and Sweden — all looking for power, packaging advantages and additional fuel economy. There are now millions of vehicles on the road powered by turbocharged 2.0-liter engines, from hot hatchbacks to luxury sedans, SUVs, family sedans and expensive two-seat sports cars.
Brands that have invested in this engine range from Hyundai and Honda to Land Rover and Mercedes-Benz. Prices for 2.0-liter turbo cars start as low as $24,775 for the Ford Focus ST and climb up to $90,700 for the BMW 740e iPerformance plug-in hybrid, which combines the engine with an electric motor and a small battery pack. 
That a car has 2.0-litre engine does not mean it can’t produce more power as seen in the case of the new Honda civic which makes 306HP that is 6HP more than the Porsche Boxster and Cayman models. Honda also uses a version of its 2.0-liter turbo in the all-new 10th-generation 2018 Accord that is just now reaching dealerships. In the Accord, the engine is rated at 240 hp. The displacement of 2.0 liters is a sweet spot that once turbocharged, delivers the performance of a large V6 with improved.
With just 170HP, the least powerful 2.0-liter turbo available is in the 2017 Volkswagen Beetle R-Line SEL. Volkswagen was one of the first automakers to pioneer this engine design, and it uses the configuration in seven models, including its new full-size three-row Atlas SUV and its legendary Golf GTI and Golf R hatchback hot hatches. The Golf R's 2.0-liter is rated 292 hp. 
Hyundai was one of the first to offer a turbocharged 2.0-liter in the midsize sedan class, which was a segment filled with big V6 engines at the time. In 2011, Hyundai deleted the V6 as its upgrade engine from its Sonata family sedan and replaced it with a 2.0-liter turbo. It was an instant success. Now Hyundai also uses the engine in its Santa Fe Sport and Tucson SUVs, as well as 1.6-liter and 1.4-liter turbocharged four-cylinder engines in some of its models. 
Lexus uses a 2.0-liter turbo is several models, including its popular IS sedan and NX SUV. A specific appeal to Lexus is the balance of performance, weight and efficiency of an engine with 0.5 liter per cylinder. The lower an engine's torque peak, the better a car can accelerate from a dead stop or up grades.
This mad rush from larger-displacement V6s to smaller, turbocharged four-cylinders was first fueled by the automakers' need to improve fuel economy to meet customer demand as well as more stringent government regulations. Fewer cylinders mean fewer parts, which means less internal friction. This makes the engine more efficient, so it burns less fuel — theoretically. But they quickly discovered other advantages and consumer benefits as well. 
The smaller engines have also allowed the car companies to make the engine compartments smaller while expanding the interior and storage space within the vehicle's footprint. And more spacious interiors and bigger trunks sell cars. The automakers we spoke with say that the downsizing of engines will continue, so for the near future at least the 2.0-liter turbo is here to stay. 

Very interesting write up. Though the 2.0 engine isn’t much naturally aspirated. I would like to see more small engines without the turbo charge et al.
ReplyDeletethat's something BMW should help us with.
DeleteV8s have been around since the 1960s?
ReplyDeleteyes. people used to fancy big engines those days
