2018 BMW M3 Complete In-depth Review & Buying Guide

The BMW 3 series has been a popular choice among car enthusiasts since its launch back in the 1990s and the German automaker has tried to continue the same legacy over these years. The latest addition to this iconic line-up is the 2018 BMW M3 sports sedan.

The BMW M3 is available in different body styles including sedan, wagon, and hatchback but as always, the sedan variant remains a popular choice among the M3 fans. The sedan still remains expensive at $66,500 and you still have to pay more for optional packages which make the overall price skyrocket.

2018 BMW M3 Features


The BMW M3 Sedan trim is available for $66,500 which also offers a bunch of exciting features like Adaptive Suspension Dampers, 18-inch alloy wheels, Keyless Ignition and entry, and LED headlights.

BMW has also provided its customers with a plethora of customization options ranging from seat upholstery and interior equipment. The robust engine makes you feel like being seated in a race car, and offer amazing drive experience.

The 2018 M3 does not have a choice of trim. It does, however, have a choice of three packages; Competition Package ($4,750), Driving Assistance Package ($500), Executive Package ($4,100).

We recommend

We recommend you go buy the M3 if you, in any capacity can, regardless of whether or not you opt for any package. Any M3 is a good M3. That said, go for the 19-inch wheels.

2018 BMW M3 Engine


“The BMW is packing serious hardware, as ever: carbon roof and driveshaft, rigid-mounted rear subframe, trick limited-slip diff. The Competition package brings different springs, larger anti-roll bars, and retuned dampers.” – Road and Track

Engine and Transmission

The 2018 M3 houses a 3.0L Inline 6-cylinder engine with BMW’s M TwinPower Turbo Technology. This beast is capable of producing about 425 hp of raw performance and a torque of 406 lb.-ft. It gets a 6-Speed Manual as standard although a 7-Speed Dual Clutch option is also available. The shifts are seamless and won’t pose any problem in daily commutes.

MSRP $66,500 $53,400 $51,400 $51,400
Engine 3.0L Inline 6-Cylinder M TwinPower Turbo 3.0L V6 Biturbo 3.0L TFSI Twin-Scroll Turbo DOHC V6 3.3L Twin Turbo V6
Transmission 7-Speed Automatic 9-Speed Automatic 8-Speed Automatic 8-Speed Automatic
Power 425 hp 362 hp 354 hp 365 hp
Torque 406 lb-ft 384 lb-ft 369 lb-ft 376 lb-ft

In terms of sheer power, the M3 kills the competition easily with its impressive figures which are around 20% better. Surprisingly, no other car comes even close to the BMW M3 in terms of engine output.


Compared to other 3.0 L engine variants in the segment, the M3 sprints 0-60 MPH in just 4.1 seconds and thus stands up to the legacy it is meant to. Similar urgency is seen in the quarter-mile run- 12.1 seconds.

(Tons/yr of CO2 Emissions @ 15K mi/year)

8.9 7.7 7.4 8.4

The only other rival that comes close to BMW M3 is the Mercedes Benz AMG C43 with its 362 hp engine but overall, no other car in the segment is capable enough to dethrone the iconic M3.

Ride and Handling

BMW definitely knows the target consumers of the M3 and has kept them in mind while engineering the handling of this sports sedan. The handling is a perfect blend of agility with comfort, which means that this beast will take over straight roads or curved tracks head-on.

BMW’s Adaptive M Suspension has also been improved with the new double-joint sprung front axle with lightweight aluminum control arms. Furthermore, Active M Differential tech helps distribute the power effectively.


To complement the sheer power, BMW has also provided large brakes in the M3 with front brakes at 15.0 inches and rear at 14.6 inches. You also get an option of adding Carbon Ceramic brakes, which feel worth the expensive price and add a whole new dimension to the driving experience.

Curb Weight(lbs.) 3630 3759 3858 3829
60-0 MPH (ft.) 101 105 117 113

The distance that BMW M3 takes before coming to a complete halt is just 101 feet, much less distance than Kia Stinger’s 113 ft. and Audi S4’s 117 ft. mark. You also get standard Emergency Brake Assist with the new M3.

2018 BMW M3 Fuel Economy


After all these fascinating talks about this performance powerhouse, let's talk about something which is a letdown. The fuel economy of the BMW M3 is below average at best as on an average, it runs only 20 miles on a gallon of fuel.

Model BMW M3 Sedan Mercedes-Benz AMG C43 Audi S4 Premium Plus Kia Stinger GT2 AWD
MPG (City) 17 20 21 19
MPG (Highway) 24 27 30 25
MPG (Combined) 20 23 24 21

Audi S4 proves to be much more efficient on the highways than the BMW M3 and in fact, certain V8 engines are more fuel efficient than the Straight Six present inside BMW M3. 

2018 BMW M3 Interior


“Everyday use is no problem for this car. It's properly sporting but totally user-friendly. The ride is supple enough for your commute, and noise will never wear you down. Its seats in particular stand out for their ability to do it all.” - Edmunds

Seating and Comfort

This 5-seater Sedan boasts one of the most spacious cabins in the segment, especially in the front row. On the rear too, you get above average headroom and legroom enough to seat even tall persons comfortably.

37.7/55.1/35.1 38.2/55.0/35.2 37.4/54.5/35.7 37.0/54.8/36.4

The seats are well padded and the option of heated seats is also available. However, cloth upholstery is standard and the company asks for more dollars if you wish to upgrade to leather upholstery, which is a turnoff considering the price you are already paying for this sedan.

Infotainment System

BMW has left no compromises when it comes to the car’s infotainment system. You get a central 8.8” touchscreen panel as standard and it is complemented by Harman Kardon 16-Speaker Surround Sound system.

The BMW iDrive user interface is fairly easy to get used to and the company also gives you an option to switch to Apple CarPlay. However, as is the case with another feature set of M3, premium packages like the Harman Audio system, Navigation, and Apple CarPlay come at an additional price.

Interior Features

There are plenty of interior features on offer too. Standard features include:

  • Power and heated front seats
  • Dual-zone climate control
  • Anthracite Carbon Structure Cloth/Leather upholstery
  • Dynamic Cruise Control

Cargo Capacity

The compact size of the BMW M3 hurts the most when it comes to the cargo capacity. The BMW M3 only offers 12.0 cubic feet of trunk volume. Then again, the potential buyers of this sedan are less likely to use the trunk any often.

Model BMW M3 Sedan Mercedes-Benz AMG C43 Audi S4 Premium Plus Kia Stinger GT2 AWD
Volume (ft. cube) 12.0 12.6 13.0 23.3

If we compare the M3 to the competition, Kia Stinger is miles ahead of everyone else, with its spacious 23.3 cubic feet trunk while Mercedes Benz AMG C43 and Audi S4 are just a notch better than the BMW M3.

2018 BMW M3 Exterior


“The M3 easily looks the part of the best-performing 3 Series. Telltale signs that this is the big dog are the “power-dome” hood bulge up front and quad tailpipe outlets in back. Compared to its lesser siblings, the new M3 has a slightly wider and longer stance, and sits lower.” – Kelley Blue Book

Dimension and Weight

Thanks to its new light-weight aluminum suspension, the BMW M3 is the lightest sedan in the bunch at 3630 lbs. It is also more compact than the other cars in the segment in terms of length but wider than the others.

Kia Stinger and Audi S4 are considerably heavier than the BMW. The Merc too, is heavier, by more than 100 pounds. Kia has the longest wheelbase here, and consequently the least maneuverability.

Exterior Features

There are some external features on the 2018 M3. These are:

  • Menacing Sporty Looks
  • Carbon Ceramic Brakes
  • Cat’s Eye LED headlights
  • Aerodynamic Design for Effective Cooling


2018 BMW M3 Safety

Safety Features on the 2018 BMW M3 Sedan consist of the following:

  • Driver’s and passenger’s front airbag supplemental restraint system (SRS) with advanced technology
  • LATCH attachment for child-restraint safety installation
  • Automatic-locking retractors (ALR) on all passenger-seat safety belts (for installation of child-restraint seats)
  • Acoustic safety-belt warning
  • Impact sensor that activates Battery Safety Terminal disconnect of alternator, fuel pump and starter from battery; automatically unlocks doors; and turns on hazard and interior lights

As is common with all the German cars, safety is a top priority and BMW is no exception. The IIHS and NHSTA ratings are not available but the M3 is equipped with tons of safety features

2018 BMW M3 Competition

BMW M3 vs Audi S4

The choice between these two German sedans totally depends on your budget. If you want to limit your expenditure, the Audi S4 has more features and performs better for the base trim but as you step higher in the price ladder, the M3 surpasses the Audi S4 easily but you end up spending way more.

BMW M3 vs Mercedes Benz C Class

Both these cars categorize as Luxury Sports sedan and simply said, the Mercedes Benz inclines way more towards the Luxury aspect while the BMW slides towards the sports side of the see-saw. Therefore, the choice will depend on your priority among these two attributes.

BMW M3 vs Kia Stinger

The Kia Stinger is a very new entrant to the sport sedan segment and yet has put the legendary cars here on notice with its throaty engine, impeccable handling, superb build quality, and practicality. All these are made even sweeter with a relatively affordable price tag. However, if you are willing to spend, the M3 offers excellent dynamics and the coveted M badge that no other rivals have to offer.

2018 BMW M3 Final Verdict

After decades (not even years)  of excellence, BMW M3 needs no special verdict. This brand has brought sports cars performance to a daily sedan and has proved its legacy through the test of time. So, any speed fanatic would go for the M3 any given day provided he can bear the extra cost.

The BMW M3 is packed with tons of features but they all come at a very expensive price point and eventually you end up paying double the price for this sedan than initially thought.
