Engine Goals Start Right Here
The B58 has quietly worked its way into everything from roadsters to rugged off-roaders. Automakers have long trusted it for its balance of reliability and flexibility. And this is a look into 20 standout cars that show what this engine can do across a variety of different builds. Let's take a closer look at the engine that could do it all.
1. BMW M340i (G20)
This quick and clean sedan pushes the B58 to 382 horsepower with standard xDrive delivering ruthless grip. Launched in 2019, it outpaces older M models without sacrificing comfort. You can hit 0–60 in 3.8 seconds while keeping four doors and all your tech conveniences intact.
2. BMW M240i (G42)
As for the 2021 M240i, it carves tight roads using BMW's tuned AWD, 369 lb-ft of torque, and near-perfect suspension geometry. Its 8-speed auto handles downshifts like a dual-clutch. Compact dimensions and 3,800 pounds help it rotate faster than heavier, pricier rivals.
3. BMW Z4 M40i (G29)
Built for fun, calibrated for precision. The 2018 Z4 M40i drops the top in 10 seconds, while the B58 delivers seamless low-end torque. An ideal 50:50 weight balance and adaptive dampers let this roadster stay composed during cornering without punishing your spine.
4. Toyota GR Supra (A90)
Launched in 2019 and co-developed with BMW, the A90 Supra pairs iconic styling with a purpose-tuned B58 engine. Torque hits early, with firmer dampers and throttle response for sharper dynamics than its Z4 sibling. The power delivery feels more urgent than refined.
5. BMW 540i (G30)
The G30 540i debuted in 2017 and pre-selects gears based on terrain and map data. This executive sedan merges comfort with calculated aggression via optional rear steering and the 335-hp B58. Over-the-air updates refine software tuning while the adaptive chassis adjusts instantly for varying road conditions.
6. BMW 545e xDrive (G30)
Here’s where hybrid meets highway punch. Debuting in 2021, the 545e adds a 111-hp electric motor to the B58’s grunt, totaling 389 horsepower. It uses intelligent energy flow to maximize efficiency. This setup lets you commute quietly and merge aggressively—on the same drive.
7. BMW X4 M40i (G02)
Style meets punch in this slope-backed utility weapon. Released in 2018, the X4 M40i uses the same mechanicals as the X3. However, it adds a lower center of gravity and tighter steering. Standard M Sport brakes and stiffer bushings give it more athletic, brake-friendly manners.
8. BMW 740i (G11/G12)
Launched with a refresh in 2019, the 740i delivers silent urgency using the B58's 335 hp. Its double-wishbone front suspension and adaptive air springs isolate bumps like a lounge on wheels. Rear passengers relax in recliners while the driver commands a live, data-rich cockpit.
9. BMW 840i (G15/G14/G16)
Low drag, long body, and smooth delivery—that's the 840i in motion. Introduced in 2018, it combines a 0.29 drag coefficient with the B58's silky torque band. Whether you're driving the coupe or convertible, the car can handle speeds above 150 mph without drama.
10. BMW X5 xDrive40i (G05)
Powering this midsize SUV since 2018, the B58 pairs with xDrive and an 8-speed auto for smooth thrust and quiet efficiency. The chassis carries over 4,800 pounds yet remains agile enough. Suspension height can be tweaked mid-drive using the self-leveling two-axle air suspension.
11. BMW X6 xDrive40i (G06)
The sloped-roof sibling of the X5, the G06 X6 xDrive40i, arrived in 2019 with added design drama and identical muscle. It combines standard Dynamic Damper Control and a lower center of gravity for flatter cornering. An illuminated grille adds flash, but the tuning's all business.
12. BMW X7 xDrive40i (G07)
Luxury doesn't mean sluggish. With seating for seven and a 5,700-pound curb weight, the 375-hp X7 moves effortlessly. This is thanks to B58 torque and 48V mild hybrid support. It tows heavy loads with ease, and rear-axle steering helps manage tight parking with full-size precision.
13. BMW M440i (G22/G23/G26)
Every M440i variant delivers straight-six energy with different flavors. The 2020 release brought sharper steering, revised cooling, and 374 hp through mild-hybrid tech. Especially in RWD spec, it balances everyday comfort with real-deal agility. Think grand tourer with a short fuse.
14. BMW 340i (F30)
As the first production car with the B58, the F30 340i made waves in 2015. The turbocharged inline-six used stronger internals, new cooling systems, and a forged crankshaft. Tuners found room to push this car well beyond factory specs. Today, many builds run over 450 hp with it.
15. BMW 440i (F32/F33/F36)
Elegance met torque when the 440i replaced the 435i in 2016. Available in different forms, it pushed out 320 hp with a new twin-scroll turbo setup. Sharp steering response and a refined exhaust note made it a standout among grand tourers.
16. BMW 745e xDrive iPerformance (G11/G12)
Hybrid power doesn't have to feel clinical. The 745e, introduced in 2019, mates the B58 with an electric motor for 389 combined horsepower. Battery placement also lowers the center of gravity, and the all-electric range is capable of reaching 16 miles.
17. BMW 640i Gran Turismo (G32)
You'll find function and comfort in the G32 640i GT. Released in 2017, it brought a liftback profile to the luxury segment, along with a spacious 21.5 cubic feet trunk. Active dampers and acoustic glass made highway cruising quieter than some flagship sedans.

18. BMW X5 xDrive45e (G05)
This plug-in SUV packs efficiency with muscle. Since 2020, the X5 xDrive45e has blended the B58 engine with a 24 kWh battery pack, giving it 30 electric-only miles. On longer drives, regenerative braking feeds power back in, optimizing both momentum and mileage on the fly.
19. Morgan Plus Six
The Morgan Plus Six launched in 2019 with a hand-built aluminum chassis and the B58 as its heart. Weighing just 2,370 pounds, it rips from 0–60 in 4.2 seconds—proof that classic styling doesn't limit advanced mechanical possibilities.
20. Ineos Grenadier
Born for trails, bred with Bavarian engineering. This rugged off-roader entered production in 2022 using a detuned B58 that prioritizes torque and durability. You'll find its twin-scroll turbo-calibrated for low-end pull instead of high revs. That's needed when climbing rocks.
