Details and features of the BMW X3 M Competition
BMW provides a variety of engines, from four-cylinders to V8s and V12s, but the six-cylinder has always been a mainstay of the company. And the X3 M40i, the six-cylinder version of the basic X3 crossover, is available. However, that is “only” the M Performance trim, which has a 3.0-liter turbocharged six-cylinder engine with 382 horsepower and 365 lb-ft of torque.
In contrast, the 3.0 liter six-cylinder twin-turbo engine in the 2020 BMW X3 M produces 473 horsepower and 442 lb-ft of torque. With more boost and a sports exhaust, the Competition increases that to 503 horsepower. Although only 10% of the parts are the same, it is actually based in part on the engine of the M40i, according to Carreports.
The X3 M additionally features an engine oil cooler, two intercooler and engine radiators, and a higher redline in addition to the extra turbo. According to Car and Driver, the BMW X3 M Competition can accelerate from 0 to 60 mph in under 3.3 seconds when equipped with an 8-speed automatic and “M-tuned” all-wheel drive. The current-generation M3 Competition actually takes longer to reach 60 mph and lags in the first quarter-mile. The X3 is also 4600 pounds heavy and has 8 “of ground clearance, according to Motor Trend. It’s not surprising that the upcoming M3 and M4 will have this engine, according to Automobile.
According to Roadshow, the BMW X3 M’s enhanced brakes have cross-drilled rotors and a limited-slip rear differential in addition to the engine. According to Car and Driver, it also boasts retuned suspension with firmer springs, a carbon fiber strut tower brace, and improved adaptive dampers. Along with the 30 additional horsepower, the Competition version also features bolstered M sport seats and firmer anti-roll bars.
The BMW X3 M Competition is undoubtedly a posh crossover. Its 10.3 rating “built-in navigation, a touchscreen, heated front seats, Apple CarPlay, and a 16-speaker Harman/Kardon music system. The forward-collision warning, blind-spot monitoring, and lane-departure warning were all standard driver aid features.
Updated Turbo, Better NVH
“To improve response and power output, we installed a new (Bosch Mahle Turbo Systems) turbocharger. We made changes to the crankshaft and crankcase to make them stronger and lighter in order to reduce noise, vibration, and harshness. These two characteristics are the primary ones that enhance NVH at higher rpms “He claims.
Faster response was one of the main goals as well. He explains, “We wanted to maintain a very wide rpm range up to a maximum of 7,000 rpm.
“The goal for maximum power was 240 kW (322 hp) between 5,500 and 6,500 rpm, but we went past that goal by more than 250 kW. (335 hp in the M240i). The goal was to reach 450 Nm (332 lb.-ft) of maximum torque at relatively low rpms, which we did at 1,380 rpm.”
With the aid of some vehicle-level enhancements, the fuel-economy target—more than a 6% improvement over the N55 in comparable vehicles—was met. According to Rulicke, “we met all of the goals we set for ourselves, including all international emission-related regulatory criteria.” He further underlines that the fuel-efficiency gain applies to both real-world customer usage and test cycles.
The trade-offs between increased performance and reduced fuel usage proved to be the most challenging aspects of building the new engine, according to him.
“But we were able to do this while both improving performance and reducing weight. Some people might argue that you can’t accomplish that because larger engine loads and heavier weights result from increased performance, yet we were able to meet both goals with our lightweight design. We were greatly assisted by our new full-aluminum crankcase, the new turbocharger, and the integration of the charge-air cooler into the intake manifold.”
The B58 six shares more than 40% of its parts (such as pistons, rods, and valvegear) with its 3- and 4-cyl. brothers despite being a brand-new member of a brand-new modular “B” engine family. It’s also the final I-6 left in a car sold in the United States after a supercharged and turbocharged “Drive-E” I-4 recently replaced Volvo’s classic I-6.
Why not adopt a V-6 like everyone else and make it simpler to package? Rulicke tells us that the I-6 is substantially lighter and smoother by nature.
Engineers are never content, therefore we wonder if there is opportunity for even greater advancement as CAFE targets continue to rise steadily.
He acknowledges that engineers always have good suggestions for improvements towards the conclusion of development. “We naturally consider how to make improvements every day, no matter how minor, for the sake of future generations because the legal restrictions will only become more stringent. But as of right now, I believe we have created a really good engine. I genuinely believe it to be the best 6-cylinder you can get.”
The 3 Series Touring now has four- and six-cylinder engines from BMW.
The new 3 Series touring model has been presented by BMW. A variety of four- and six-cylinder gasoline and diesel engines are available for the 3 Series Touring.
The most recent six-cylinder in-line gasoline engine from the OEM powers the new BMW M340i xDrive Touring. The straight-six engine’s peak torque is 500Nm, and its top output is 380ps, allowing it to go from 0 to 100 km/h in 4.5 seconds.
The 2-liter four-cylinder petrol engine utilized by BMW for the 330i has a maximum output of 260 horsepower, an increase of 6 horsepower over the model it replaces, and a peak torque increase of 50 Nm to 400 Nm. The additional power results in a 5.9 second time from 0 to 100 km/h.
The new BMW 320i Touring’s 2-liter four-cylinder engine produces 184 horsepower and a maximum torque of 300 Nm. This implies a 7.6 second period from 0 to 100 km/h.
The 3-liter, six-cylinder engine in the new BMW 330d has a maximum power of 268 ps and a maximum torque of 580 Nm. In 5.4 seconds, this device propels the 330d from a standstill to 100 km/h.
Additionally, the 2-liter, four-cylinder diesel engines in the BMW 320d Touring, BMW 320d xDrive Touring, and BMW 318d Touring models have undergone extensive modifications to the BMW TwinPower Turbo technology. The BMW 320d Touring sprints from 0 to 100 km/h in 7.5 seconds thanks to the new diesel engine, which has a maximum output of 192ps and a maximum torque of 400Nm.
In contrast, the brand-new BMW 320d xDrive Touring will achieve 57.6–61.4 mpg and emit 129–121g/km of CO2. The new BMW 318d Touring’s engine produces 152 horsepower and a maximum torque of 320 Nm. With these numbers, it takes 8.9 seconds to accelerate from 0 to 100 km/h.
In the summer of 2020, a plug-in hybrid drive will also be added to the model lineup. The BMW 330e Touring has an electric drive system included into the eight-speed Steptronic transmission in addition to a four-cylinder gasoline engine. The driving system as a whole can provide a maximum output of 296ps.
2020 Wards 10 Best Engine and Powertrain Award winner is the BMW B58 TwinPower Turbo 3.0-Liter Inline Six-Cylinder Engine, which produces 382 horsepower.
The crankcase and cylinder head of this revised, award-winning 3.0-liter inline six-cylinder engine are made of aluminum. Boost pressure is created more quickly using a new single Twin-scroll turbocharger that has an integral, small steel exhaust manifold and impellers that weigh around 25% less than those of previous models. New High Precision Injection technology, which permits injection pressures up to 5,076 psi, is used to supply fuel. Additionally, Double VANOS variable camshaft control and VALVETRONIC fully variable valve control are included in the most recent iteration of M TwinPower Turbo technology.
Ralph Mahler, Head of Product Planning and Strategy for BMW of North America, accepted the honor on behalf of everyone at BMW who has toiled assiduously and passionately to put the new engine into production. For more than eighty years, the inline six-cylinder engine has been the Ultimate Driving Machine’s “heart and soul,” according to Mahler. “Every new upgrade makes the engine’s refinement, smoothness, power delivery, and efficiency even better; these are all qualities that our customers love now and will undoubtedly continue to do so for a very long time. We are incredibly appreciative and thankful for the WardsAutos jury’s acknowledgment.”
The BMW 303 sedan’s 1.2 liter 30 hp inline six-cylinder engine marked the start of BMW’s inline six-cylinder passenger car engine history 87 years ago. The 3.0-liter inline six-cylinder engine design, which comes in versions with 335 horsepower to 503 hp, is one of the most adaptable in the current BMW range and can be found powering vehicles from practically every BMW model line.
The B58 inline six-cylinder turbo we tested in the more powerful X5 last year won with 335 horsepower. remarked Tom Murphy, managing editor of WardsAuto. “Now, a year later, it is presented to us in the completely new 3-Series, which is significantly lighter and has an added 47 horsepower. The B58 is much better today than it was back then. The M340i stretches its legs and emits a wonderful, throaty exhaust noise, particularly when shifting speeds with the paddle shifters. This engine is extremely adaptable, excellent for daily driving, and exhilarating when driven hard.”
The new 6-cylinder diesel from BMW increases power.
BMW will introduce a more potent six-cylinder engine family this year that will include a 48-volt system, capping a three-year overhaul of its engine lineup.
The next X5 and X6 SUVs as well as the new 3-series range will both feature the engines.
According to a paper given at the annual Vienne Motor Symposium and led by BMW engineer Fritz Steinparzer, the engine’s 30d variation will produce 286 horsepower, up from 266 horsepower, and the 40d variant would produce 340 horsepower, up from 326 horsepower.
Since 1998, BMW has increased the power of its six-cylinder engines by almost double (see chart, below).
A crucial part of the automaker’s efforts to comply with EU6d emissions regulations is the second generation of the six-cylinder modular family from BWM.
Important elements in achieving that goal include:
- a water pump with an electromechanical drive that runs on 48 volts
- a dual-variable turbine geometry two-stage charging system (VTG)
- a needle closure control (NCC)-equipped high-pressure common-rail injection system.
Is the 6-cylinder BMW 328i real?
The turbocharged 4-cylinder N13, 4-cylinder N20, and 6-cylinder N55 engines were initially used in the petrol variants. This resulted in the 328i models’ turbocharged 4-cylinder N20 engine replacing their conventional normally aspirated 6-cylinder powerplants. The engines were changed to the 3-cylinder B38, 4-cylinder B48, and 6-cylinder B58 for the 2016 facelift (LCI).
The 4-cylinder N47 and 6-cylinder N57 turbocharged engines were initially used in the diesel variants. The 4-cylinder vehicles received the B47 engine update for the 2016 facelift, but the 6-cylinder models kept the N57 engine.
Has BMW ever produced V6 engines?
For many years, V6 engines have been a mainstay of the BMW lineup. Even more power and efficiency are delivered by the turbocharged V6 engine. And in many ways, it competes favorably with the V8. The turbocharged V6 engine’s highlights are as follows:
- excellent fuel efficiency
- a small footprint that accommodates various model sizes
- more horsepower than I4s and regular V6s, which are less potent engines.
