The American magazine WardsAuto 25 times named the winners of the competition “10 Best Engines” for cars 2019 model year. In the list of favorites included the 3.0-liter turborestore BMW B58, which is installed on the BMW X5, and the power plant hydrogen crossover Hyundai Nexo.
This year the squeak of applicants was 34 cars, power plants which the publication’s editors tested in October and November during normal travel in the vicinity of Detroit. The present victory of the BMW X5 is a 35th victory of the Bavarian brand in the competition “10 Best Engines”. In 28 cases, the jury awarded exactly inline “six” BMW. The list of winners for the second consecutive year were two of the Ford, and Hyundai brand for the first time received two awards.
TOP 10 2019 year according to WardsAuto looks like this (in alphabetical order by brand):
- 3.0 l (B58) DOHC turbocharged I-6 (BMW X5)
- 6.2 l OHV V-8 with DFM (Chevrolet Silverado)
- 5.0 l DOHC V-8 (Ford Mustang GT / Bullitt)
- 3.0 l DOHC TurboDiesel V-6 (Ford F-150)
- 2.0 l Atkinson DOHC i-VTEC 4 – cyl./HEV (Honda Accord Hybrid)
- The fuel cell 120 kW electric power plant (Hyundai Nexo)
- The power plant is 150 kW (Hyundai Kona EV)
- 2.0 l DOHC VC-Turbo 4-cyl. (Infiniti QX50)
- 2.0 l DOHC Atkinson 4-cyl./HEV (UX Lexus 250h)
- 3.6 l DOHC Pentastar eTorque V-6 (Ram 1500)
The selection of the winner in the edition of WardsAuto explained by the fact that the upgraded “turborestore” BMW X5 (340 HP) feels much better during surges to the Redline. B58 debuted a few years ago and now have a new cooling system, head, timing chain, oil pump and forged crankshaft. In addition, BMW engineers have improved the units and the air intake system, and installed a new fuel system.
Unit V8 6.2 DFM Chevrolet Silverado (426 HP) has once again proved that, despite the rising requirements for fuel consumption, volumetric “eight” too early to write off. Ways to improve the efficiency of these motors exist. In the updated small block 6.2 L GM engineers used the advanced technology of cylinder deactivation Dynamic Fuel Management (DFM), which in real conditions on every liter of petrol you can drive 0.8 miles better than DFM. The trick is that DFM is able to deactivate the valves in any cylinder separately, which provides 17 combinations of cylinders. A sophisticated controller determines 80 times per second, how many cylinders need fuel, and the system continuously switches the start sequence depending on the driving conditions and inputs of the throttle. This happens so smoothly that the driver sees only fewer stops at the pump.
The second “eight” in the list of winners – the 5.0-liter V8 engine of the sports car Ford Mustang Bullitt power 486 HP, which the jury commented: “a Perfect version of the Bullitt made us smile every time we pressed the gas.” In Bullitt version of the output of the motor more than the normal GT version only 20 HP, but installing the intake system from the Shelby GT350 and more “free” exhaust system with switchable valve allowed him to be among the winners.
Once again the list of winners was the Ford pickup F-150. This year the jury noted 253-horsepower turbodiesel V6 3.0 Power Stroke, providing a Ford F-150 has the lowest fuel consumption among full-size pickups in the tests WardsAuto – 9.0 l/100 km. in addition, noted the ability of the pickup to tow a trailer weighing up to 5171 kg and carry up to 916 kg of payload.
Hybrid engine-sedan Honda Accord Hybrid (2.0 l DOHC iVTEC Atkinson and two electric motors) like a jury not only low fuel consumption (5.8 l/100 km), but quiet and smooth operation, fast switching between types of actuator (electric, ice and hybrid). As the jury noted a modest starting price of the sedan is $25 320.
Hyundai brand scored with two environmentally friendly models. In the “top ten” was a crossover Nexo hydrogen fuel cell (163 HP) and 204-horsepower electric crossover Kona EV. According to WardsAuto, Kona is the “long-range” electric car on the US market in addition to Tesla models, but the Nexo is the “time machine that sends you into the future.” Cylinders with hydrogen (6.35 kg of gas) provide Nexo mileage 612 miles on the EPA cycle. The reserve Kona EV with a battery capacity of 64 kWh is 415 miles on the EPA standard.
“I never thought I would live to see the day when the car is on fuel cells and electric cars with battery will fall in the same year, and two powerful V8 and a complex 4-cylinder engine with variable compression”, – said the senior content Director of WardsAuto, drew winter.
Crossover Infiniti QX50 was among the winners thanks to the 2.0-liter engine with variable compression ratio (the first production in the industry), issuing a us spec 272 HP, the Jury noted the “surprisingly good responsiveness”. Due to the geometric compression ratio varying in the range of 8.0:1-14.0:1 motor 2.0 VC-Turbo can adapt to the current load.
The 2.0-liter “aspirated” from the line of Dynamic Force, operating on the Atkinson cycle under the hood, hybrid crossover the Lexus 250h UX, were lauded by the jury for its low fuel consumption, which at the time of tests amounted to 6.1 l/100 km In the power plant of the crossover it is supplemented by three electric motors (two in front, one on the rear axle). The nominal combined capacity of the system is 183 HP.
Also in the TOP 10 was the upgraded version of the 3.6 Pentastar V6 motor eTorque installed on the Ram pickup truck 1500. The unit is supplemented by a 48-volt belt-driven generator, which acceleration may briefly add to 176 Nm of electric traction to the nominal 365 Nm at the engine. The electric motor is powered from a separate battery, rechargeable by recuperation of the braking. The effectiveness of the system has proven a fuel consumption test WardsAuto 10.6 l/100 km.
