As of October 4, 2026, the verified new-car examples in the U.S. are turbocharged six-cylinder models; the available evidence does not verify a new factory-supercharged six-cylinder car. That is not proof that none exists in every market. The strongest choices here span BMW sport sedans and coupes, Toyota’s two-seat GR Supra, Porsche’s hybrid-assisted 911 Turbo S, and Mercedes-AMG’s announced E 53 Hybrid Wagon. The picks are organized by the kind of car you want, not by independent road-test results.
What counts as a supercharged or turbocharged six-cylinder car?
A six-cylinder engine has six cylinders; turbocharging and supercharging are two different ways of forcing more air into an engine. In a turbocharger, exhaust flow spins a turbine that drives a compressor. A supercharger is driven mechanically by the engine. The verified current U.S. examples in this guide use turbochargers. Porsche’s 911 Turbo S and Mercedes-AMG’s E 53 Hybrid Wagon also use electric motors, so their combined-system power is not the output of the six-cylinder engine alone.

- DIMENSIONS AND DISPLAY USE: The completed DM111 measures approximately 7.68 × 5.12 × 7.32 inches and weighs about 5.80 pounds. It can be displayed in a home, office, studio, workshop, classroom, or automotive-themed collection.
Best BMW choices for a sedan or coupe
BMW M340i: the sport-sedan choice
BMW USA lists the M340i with a 3.0-liter turbocharged inline-six. It is the most direct fit here if you want a sedan rather than a two-seat sports car. The cited listing does not provide a price or a specific output figure for the M340i, so confirm the current configuration and price with BMW before comparing it numerically with the Supra or the hybrid models.
BMW M440i: the coupe alternative
The M440i brings the same basic engine description—a 3.0-liter turbocharged inline-six—to a coupe format. Choose it over the M340i if the coupe body matters more than sedan practicality; the evidence cited here does not establish a direct performance or price comparison between the two.
Rank #2
- Compatible with Models: Fit for Dodge RAM 2500 (5.9L L6) 2005-2009, fit for Dodge RAM 2500 (6.7L L6) 2007-2010, fit for Dodge RAM 3500 (5.9L L6) 2005-2007, fit for Dodge RAM 3500 (6.7L L6) 2007-2010, fit for Memory 2500-3500 (6.7L L6) 2011-2017
- Smooth Gear Shifting: Master and slave cylinders work together, hydraulic transmission system is more precise, clutch operation is smoother, and pedal is easier, which helps to improve gear shift response speed
- Pre-Filled Design: Hydraulic oil is pre-filled and exhaust seal is set before leaving the factory. Master and slave cylinder can be used after installation without bleed or add fluid
- Durable Materials: Master cylinder and slave cylinder are made of high-strength metal and high-quality rubber sealing rings, which have good high temperature resistance, corrosion resistance and pressure resistance, can effectively reduce hydraulic leakage
- Easy Installation: Equipped with complete hydraulic pipelines, interface position is accurate, no additional modification is required, and old parts can be directly replaced, which is easy
BMW 540i and 740i: six-cylinder luxury sedans
BMW USA also lists the 540i and 740i with 3.0-liter turbocharged inline-six engines. They broaden the choice beyond compact sport-oriented models: consider them if you want the six-cylinder configuration in a more conventional luxury-sedan format. The cited listing does not establish their prices, outputs, or a ranking against the M340i and M440i.

The 2026 GR Supra 3.0 is a rear-wheel-drive, two-seat coupe with a 3.0-liter turbocharged inline-six. Toyota lists 382 hp, 368 lb-ft of torque, and a $58,300 starting MSRP. Buyers can choose a six-speed manual or an eight-speed automatic. Toyota’s listed estimated fuel economy is 22 mpg city and 29 mpg highway.
Rank #3
- OE Style; with High Output Engine
- Compatible with or fits: 2019 - 2023 Ram 3500 6.7L 6 Cyl Turbocharged Diesel
- Radiator Cap Not Included
- OEM Style Plastic Tank & Aluminum Core; 2-Row
- Radiator - Compatible with 2019 - 2023 Ram 3500 6.7L 6-Cylinder Turbo Diesel
The Supra is the clearest choice in this group if you want a manual-transmission option in a compact, two-seat sports-car layout. Its two seats and coupe packaging are the practical trade-off: it is not the right format for carrying more passengers or prioritizing sedan or wagon utility.
How the Supra compares with the Nissan Z Sport
Toyota’s 2026 comparison page lists these figures for the GR Supra 3.0 and Nissan Z Sport. They are Toyota-published, trim-specific comparison figures, not independent tests.

| 2026 model/trim | Starting MSRP | Power | Torque | Estimated city/highway economy | Drive |
|---|---|---|---|---|---|
| Toyota GR Supra 3.0 | $58,300 | 382 hp | 368 lb-ft | 22/29 mpg | Rear-wheel drive |
| Nissan Z Sport | $42,970 | 400 hp | 350 lb-ft | 19/28 mpg | Rear-wheel drive |
On Toyota’s figures, the Z Sport has more horsepower and a lower starting MSRP, while the Supra has more torque and higher estimated city and highway fuel economy. Treat that as a comparison of the listed trims and published figures, not a complete ownership-cost or driving-experience verdict.
Best high-performance hybrid-assisted sports car: 2026 Porsche 911 Turbo S
Porsche announced a 2026 911 Turbo S with a twin-turbo six-cylinder boxer engine and T-Hybrid technology. Porsche gives the car a 701 hp system output and claims a 0–60 mph time of 2.4 seconds. Those are manufacturer figures; 701 hp is combined system output, not an engine-only rating, and the acceleration claim is not an independent test result.

This is the high-performance option for a buyer considering a hybrid-assisted 911 rather than a conventional sedan or a modestly priced sports coupe. The cited announcement does not state a price, so it is not possible to make a price comparison with the Supra from these figures alone.
Best performance wagon: 2026 Mercedes-AMG E 53 Hybrid Wagon
Mercedes-Benz USA announced the 2026 U.S.-market AMG E 53 Hybrid Wagon with an AMG-enhanced 3.0-liter turbocharged inline-six paired with an electric motor. Mercedes-Benz lists 577 hp of combined standard output, rising to 604 hp with optional Race Start. These are combined-system figures; they should not be read as the six-cylinder engine’s output by itself.
The wagon body makes this the utility-oriented entry among the performance options here. The announcement establishes the model and its specifications, but it does not establish that a particular dealer has one available to buy on October 4, 2026. Check local orderability and inventory before treating it as an immediately obtainable choice. The cited announcement does not state a price.

- Consider the 540i or 740i if a luxury-sedan format is a higher priority than a compact sport sedan or coupe.
- Choose the Supra 3.0 if a two-seat, rear-wheel-drive sports coupe and the choice of manual or automatic transmission suit your needs.
- Consider the 911 Turbo S if you want Porsche’s announced T-Hybrid 911 and are comparing high-performance system output rather than engine-only output.
- Consider the E 53 Hybrid Wagon if wagon utility matters alongside hybrid-assisted performance, after confirming local availability.
For any specific purchase, compare the exact model year, trim, drivetrain, options, and current dealer price. The examples here establish that turbocharged six-cylinder choices span several body styles in the U.S.; they do not establish a verified new factory-supercharged choice or a road-tested winner.
