5 Groundbreaking New Engines For 2016 You Need To Check Out

Published June 1, 2015

The 2016 model year has a bumper crop of technically sophisticated new engines coming. Coming in gas, diesel, and hybrid, there’s something for every driver.

The engineers at the five companies were highlight here have definitely been burning the midnight oil, as the engines they are introdocuing each advance the state of the art in their respective categories.

BMW B58 3.0L Straight Six

BMW’s all-new B58 Turbocharged Six Cylinder Engine

The BMW 340i, the new top of the line 3 Series, is motivated by an an entirely new all-aluminum 3.0-liter straight-six engine code named B58, replacing the successful N55.

BMW has been very tight-lipped about this engine and has provided no details as to its internal configuration and has released just a single photograph.

What we do know is that the engine utilizes a single, twin scroll turbocharger to boost the power, which produces 320 horsepower between 5,500 and 6,500 rpm and 330 lb-ft. of torque from a rather low 1,380 rpm, indicating the car should feature excellent initial acceleration. The six comes standard with an eight-speed automatic transmission, but a six-speed manual with a rev-matching function is available as a no-cost option.

2016 Toyota Prius High-Efficiency Four Cylinder

The key to fuel economy in all internal combustion engines is Thermal Efficiency, which is the energy in the fuel converted into piston motion by burning gasoline. An average gasoline powered car is about 30% thermal efficient, which means the other 70% is converted to other forms, mostly heat (in other words, a car engine is a better heater than a passenger vehicle, same as a standard light bulb is a better heat source than light source).

The engineers at Toyota have developed a gasoline engine for the 2016 Prius 2016 hybrid vehicle is rated at 38.5%, an increase in efficiency of 28%. In fact, in independent test runs, the new Prius motor achieved 40% efficiency.

Keys to the improvements include and increase of EGR from 21% to 28%. They also had to increase the combustion speed of the fuel and air mixture inside the combustion chamber my modying the cluylinder head and piston tops. The changes made it difficult to ignite the mixture so the electrical energy delivered to the spark plugs was increased from 35 millijoules to 100 millijoules, the level used in modern racing engines. The net result is an expected 55 MPG rating.

Nissan Titan XD Cummins M2 Diesel

The 5.0L V8 Turbo Diesel brings together a compacted graphite iron (CGI) cylinder block, forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers to offer maximum durability in a lightweight package. These features, along with dual overhead camshafts, also contribute to the excellent noise, vibration and harshness (NVH) characteristics achieved by the 5.0L V8 turbo diesel.

The Nissan Titan XD Cummins diesel is the first commercial application of the new Cummins DOHC V-8 with the M2 two-stage turbo system, which helps reduce traditional turbo-lag through precision balancing between high-pressure and low-pressure turbos. The patented Rotary Turbine Control provides more consistent performance across the rev range and better manages the temperature of the exhaust gases.

The new engine also features a Bosch HPCR fuel system to deliver precise fuel control and the increasingly more common multiple injections per combustion stroke, which helps increase efficiency and reduce traditional “diesel clatter.” And, the advanced, maintenance-free glow plugs provide quick engine starts, even in extreme low temperatures.

Another key advantage of the new Cummins diesel design is that it provides maximum durability and power in a lightweight package. Weight was reduced by building the cylinder block out of compacted graphite iron (CGI), which is stronger and lighter than traditional iron, plus the use of aluminum cylinder heads and composite valve covers.

GM Duramax XLD 2.8L Turbocharged Diesel

The Chevrolet Colorado has been a reliable if necessarily stellar performer in the GM truck line. That may all change this fall when the 2.8-liter Duramax diesel four-cylinder engine gets dropped into Chevy’s mid-sized truck offering.

The Duramax XLD 2.8-liter diesel produces 181 horsepower and 369 lb-ft of torque and the same six-speed automatic transmission as 3.6-liter V6 equipped Colorado, which will definitely put the pressure on the Ram Eco Diesel for leadership in diesel pickup-truck fuel economy.

Basic specs are a 3.70″ bore and a long 3.94″ stroke, dual overhead camshafts, four vales per cylinder, high-pressure direct injection, and a water-cooled, variable geometry turbo. Rumor has it the fuel injection system is capable of 5 consecutive injections at 230 microsecond intervals.

The engine has been available in markets outside the US for several years. GM says they are “re-tuning” the four cylinder motor for the US market. Unlike the LML, where GM collaborated with Isuzu on the design, the 2.8L four cylinder was designed with VM Motori, an Italian design consultant and diesel engine manufacturer that has since been purchased by Fiat Chrysler.

Honda Type R 2.0L i-VTEC Turbo Engine

Honda stunned observers at the Geneva Motor Show this Spring when it introduced its new Civic Type R features a 2.0 liter, direct inject, turbocharged version of its Earth Dreams i-VTEC Turbo engine. In Type R tune, the engine produces 305HP and 295 lb-ft of torque. The engine red lines at 7,000rpm, and delivers peak torque from as little as 2,500rpm.

With that kind of grunt Honda claims the Type R will hit 60 mph in 5.7 seconds and keep rolling to a top speed of 167 mph.
