The General hasn't produced a three-bonker for the U.S. in nearly 20 years.
Always on the hunt for better fuel economy, General Motors is reviving the three-cylinder engine for future models in North America. It's the first time GM has offered a three-pot stateside in nearly two decades.
A pair of new engines will surface in the 2021 Chevrolet Trailblazer and next-gen 2020 Buick Encore GX, displacing 1.2 liters and 1.3 liters. They are based on similar versions revealed abroad, although power ratings for U.S.-bound engines aren't available just yet. Given their relatively modest subcompact applications, don't expect them to suck you into the seat.
That said, some innovative tech and turbochargers will provide extra boost, allowing the new mills to create power similar to their four-cylinder counterparts while reducing fuel consumption. Such tech includes an electrically assisted wastegate system, an electrically driven water pump, and an active vacuum system to help relieve parasitic load on the engine. Because they feature newer tuning, weigh around 40 pounds less, and have one fewer cylinder, they'll likely score better fuel economy numbers and emit fewer emissions than the equivalent four-cylinder engines they replace.
One of the latest versions of GM's 1.3-liter Ecotec made its debut in the Korean-specification 2019 Chevrolet Malibu, producing 156 horsepower and 174 pound-feet of torque. That's about on par with the Encore's former top-spec 1.4-liter turbo four, which made 153 hp and 174 pound-feet. Buick discontinued that engine option for the current Encore in its last year of production before the second-gen's arrival in early 2020. The new three-cylinders are expected to produce similar power.
BMW N55 straight-six engine. The inline-six engine has all but died out, aside from the Bavarians, though. Packaging and cost have brought about the mass use of V6 engines to replace the I6, as V6. 6/1 Lister Type Diesel Engine - Build your own Lister Type Diesel Generator to your specifications! Just add your own 2 pole (3600 RPM) or 4 pole (1800 RPM) generator head and cooling system! This engine's simple, tried-and-tested design is known worldwide for its extreme simplicity, ease of starting, remarkable fuel economy and reliability.

The supercharged 3.5-liter V-6 stuffed inside the new Evora 400 might be sourced from Toyota, but you wouldn't guess it by the noise it makes. It sounds more like a racing engine than anything else.

The Detroit giant has been offering three-cylinder engines since the mid-1980s, but not always for the U.S. market. Previously, GM had offered a three-smasher in North American-spec Chevrolet and Geo Metro models, although those were killed off following the 2000 model year. The Metros featured a naturally aspirated, 1.0-liter mill, developed with Suzuki, that produced 55 hp.
Since then, GM has teamed up with its former Opel subsidiary (now owned by PSA), the Shanghai Automotive Industry Corporation (SAIC), and MG Motor to produce a new Ecotec inline-three for subcompact Opel, Vauxhall, Chevrolet, and Buick models in overseas markets. The new three-cylinder engines will reportedly be built at GM's plant in Mexico alongside other North American market GM vehicles.
Chevrolet's arch rival Ford, with its 1.0-liter EcoBoost, is the most recent American manufacturer to offer a three-cylinder engine in the U.S. Vuescan trial. Ford dropped that engine from the now-extinct Fiesta and Focus sedans, but it lives on in the EcoSport subcompact SUV. BMW also has a small-displacement three-pot in its lineup that often shows up under the hood of various Mini models.

The MDX draws both power and efficiency from a 3.5-liter, 290-horsepower V-6 engine81 that features Direct Gas Injection, Variable Cylinder Management™ (VCM®) and the Acura i-VTEC® system.
- Intelligent Variable Timing and lift Control (i-VTEC) increases horsepower by advancing valve timing relative to engine rpm. High-rpm airflow is enhanced at approximately 4,500 rpm when intake valve openings are extended deeper and for longer duration.
- VCM® significantly improves highway fuel efficiency by automatically changing the V-6 engine to run on six or three cylinders, depending on driving conditions. The cylinder activation is so seamless, it will likely go unnoticed by your passengers.
- Direct Gas Injection injects fuel directly into each cylinder for a more precise and effective air fuel mixture. It also uses significantly less fuel during engine starts. The cooling effect of fuel injected directly into the cylinder allows the incorporation of the power-increasing effects of a higher compression ratio without engine knocking.
- The Drive-by-Wire throttle system varies throttle sensitivity to provide the appropriate throttle response and feel to different driving conditions.
- The net result? The MDX engine produces 290 horsepower at 6200 rpm, and 267 lb.-ft. of torque (SAE net) at 4500 rpm and has an EPA Fuel Economy Ratings97 of 20 / 27 / 23 MPG (city/highway/combined) for the front-wheel drive model and 19 / 26 / 22 for the SH-AWD® model (19 / 25 / 21 for SH-AWDA-Spec).
