2018 BMW 3-Series Overview

Is the 2018 BMW 3 Series a Good Used Car?

Yes, the BMW 3 Series is one of the most well-rounded options in the luxury small car class.

The 2018 3 Series has many highlights:

  • Multiple body styles
  • Handsome interior with quality materials
  • User-friendly iDrive infotainment system
  • Enjoyable ride and handling
  • Powerful engine options
  • Great fuel economy

It has a couple drawbacks though:

  • Higher asking prices than many competitors
  • Few standard safety features

Overall, the 3 Series is a fine pick, but you may want to consider rivals like the 2018 Kia Stinger or 2018 Lexus IS if you’re looking for performance and luxury at a lower price. You may also want to check out the 2018 BMW 4 Series, which is available as a coupe and a convertible.

How Much Does the 2018 BMW 3 Series Cost to Own?

The 3 Series’ five-year costs for gas, insurance, repairs, and maintenance are projected to be about $28,600, or $5,720 per year. That’s average for a luxury small car.

Is It Better to Buy a Used or New 3 Series?

If you’re shopping for a BMW sedan, you should strongly consider the fully redesigned 2019 3 Series. This new car has updated exterior styling, a higher-quality interior, and a more advanced infotainment system.

On the other hand, it’s better to buy a 2018 model if you’re shopping for a 3 Series wagon or hatchback. These body styles carried over unchanged for 2019. As a result, you’re apt to save money with a 2018 model that’s nearly identical to the 2019.

You can save even more money by shopping for a used 3 Series from the 2012 through 2017 model years. These vehicles are all part of the same generation, and they all have agile handling and similar styling. However, there are a few important updates to be aware of.

For 2014, BMW added the wagon and hatchback body styles, as well as the diesel-powered 328d model. BMW also discontinued the 3 Series coupe and convertible that year, and those models were replaced by the 2014 BMW 4 Series. A refreshed M3 variant arrived for 2015, followed by the 330e plug-in hybrid model for 2016. Support for Apple CarPlay first became available for the 2017 model year.

Which Used BMW 3 Series Trim Is Right for Me?

The 2018 BMW 3 Series is available in multiple configurations. There are six trim levels: 320i, 328d, 330i, 330e, 340i, and M3. The main differences between the trims boil down to the car’s engine and standard features. There are also three body styles: sedan, Sports Wagon, and Gran Turismo hatchback.

The base model 320i is a fine option for everyday driving, but we suspect most shoppers will prefer the 330i. It offers peppier acceleration, and it’s available in every body style.

  • BMW 320i: The entry-level 320i is only available as a sedan. It has a 180-horsepower turbocharged four-cylinder engine. Standard features include a 6.5-inch infotainment screen, Bluetooth, a USB port, HD Radio, satellite radio, a CD player, dual-zone automatic climate control, synthetic leather upholstery, keyless entry, push-button start, a rearview camera, rain-sensing windshield wipers, and 17-inch alloy wheels.
  • BMW 328d: The 328d model is available in sedan and wagon body styles. It has a 180-horsepower turbodiesel engine and power-adjustable front seats. The wagon version adds a moonroof and a power liftgate.
  • BMW 330i: The midrange 330i trim comes in the sedan, wagon, and hatchback body styles. It has a 248-horsepower turbocharged four-cylinder engine.
  • BMW 330e iPerformance: The 330e sedan model comes with a 248-horsepower plug-in-hybrid powertrain.
  • BMW 340i: The sportier 340i trim is available in sedan and hatchback body styles. It adds a 320-horsepower turbocharged six-cylinder engine, 18-inch wheels, and a Harman Kardon sound system.
  • BMW M3: The performance-focused M3 sedan has a 425-horsepower twin-turbocharged six-cylinder engine. This trim adds navigation, genuine leather upholstery, heated front seats, and an adaptive suspension. These features are available on the lower trims as well. An M3 Competition package is available, and it boosts this engine up to 444 horsepower.

Available features include Apple CarPlay, a heated steering wheel, heated rear seats, rear sunshades, a suite of active safety features, and high-performance brakes.

What Does BMW's Certified Pre-Owned Warranty Cover?

The BMW Certified CPO program is available on vehicles no older than five years with between 300 and 60,000 miles on the odometer. The program covers buyers for one year with unlimited mileage after the four-year/50,000-mile new-vehicle limited warranty has expired. This warranty can be renewed for a fee, but there is a maximum of five years of coverage. Each BMW must pass a road test and a 196-point inspection before earning CPO status. Additional benefits like towing and 24-hour roadside assistance may be available. This CPO coverage can be transferred to subsequent owners, but some restrictions may apply, so read the BMW warranty page carefully.

BMW has one of the less-attractive CPO programs among luxury car manufacturers, according to our research. You’ll get better warranties from Mercedes-Benz, Audi, and Jaguar.

How Safe Is the 3 Series?

The Insurance Institute for Highway Safety named the 3 Series a 2018 Top Safety Pick. The car earned a top rating of Good in five crash tests. The 3 Series’ headlights earned mixed reviews. The standard lights received the lowest rating of Poor for how well they illuminate the road ahead, while models with the available adaptive LED lights received the second-highest rating of Acceptable. BMW 3 Series models equipped with the City Collision Mitigation system received the second-best rating of Advanced for front crash prevention, and models with adaptive cruise control received the lowest rating of Basic.

The National Highway Traffic Safety Administration gave the 2018 3 Series an overall safety rating of five out of five stars. The 3 Series received five stars in the side crash and rollover tests and four stars in the frontal crash test.

2018 BMW 3 Series Versus the Competition

Which Is Better: 2018 BMW 3 Series or 2018 Audi A4?

The 2018 Audi A4 is another great option in the luxury small car class. Both the 3 Series and the A4 have quality interiors, user-friendly features, and comparable projected ownership costs. Both models typically demand similar asking prices as well. Opt for the A4 if tech and safety are a priority, since it has more standard features. On the other hand, stick with the 3 Series if performance is more important. The BMW drives like a true sports sedan, and it offers a wider array of available engines, including some with better fuel economy than the A4.

Which Is Better: 2018 BMW 3 Series or 2018 Mercedes-Benz C-Class?

The 2018 Mercedes C-Class outshines its BMW rival in one area in particular: its interior. The C-Class boasts top-notch cabin materials, opulent styling, and an exceptional attention to detail. It also rides quite comfortably. That said, the 3 Series is a better fit for most drivers. Its infotainment system and tech features are easier to use. Its ownership costs are projected to be much lower, and the BMW is often far less expensive than the Mercedes.

2018 3 Series Performance

How Does the 2018 BMW 3 Series Drive?

The 3 Series provides a very rewarding driving experience. It feels lightweight and stable around turns, with quick and responsive steering and brakes that slow the car down confidently. The 3 Series also rides comfortably on everyday road surfaces. You can feel ripples and slight changes in the road surface, but the suspension soaks up larger bumps and dips. An adaptive suspension is available – it comes standard with the M3 – and it sharpens the car’s handling while providing a decent ride.

The 3 Series is available with six different engines, and each earns praise for its smooth operation. The entry-level 320i and turbodiesel 328d supply ample power for driving around town and hustling up to highway speeds. Both can scoot from zero to 60 mph in just over seven seconds. The 330i, 330e, and 340i move the 3 Series into sports sedan territory. These models can accelerate from zero to 60 mph in the five- to six-second range, and each offers brawny passing power. The twin-turbocharged M3 is a beast. It can tackle the zero-to-60 sprint in just four seconds.

Most models are equipped with a smooth-shifting eight-speed automatic transmission that delivers prompt gear changes. The optional six-speed manual is fun to shift as well, and the M3’s available dual-clutch automatic transmission is similarly refined.

  • Base engine: 180-horsepower turbocharged four-cylinder (320i)
  • Available powertrains:
    • 180-horsepower turbodiesel four-cylinder (328d)
    • 248-horsepower turbocharged four-cylinder (330i)
    • 320-horsepower turbocharged six-cylinder (340i)
    • 425-horsepower twin-turbocharged six-cylinder (M3)
    • 444-horsepower twin-turbocharged six-cylinder (M3 Competition)
    • a four-cylinder turbocharged engine and an electric motor with a combined 248 horsepower (330e iPerformance)
  • Drivetrain: standard rear-wheel drive; available all-wheel drive (xDrive)
  • Transmissions: standard eight-speed automatic; available six-speed manual; available seven-speed dual-clutch automatic
Does the 2018 BMW 3 Series Get Good Gas Mileage?

  • 328d, AWD: 30/40 mpg
  • 320i, with automatic, RWD: 24/35 mpg

2018 3 Series Interior

How Many People Does the 2018 3 Series Seat?

The 3 Series is available in three body styles, and each has five seats. The front seats are comfortable and nicely padded, and they provide ample head- and legroom, even for taller occupants. The range of seat and steering-wheel adjustments make it easy to find an ideal driving position as well. The rear seats are similarly cozy, and they offer enough space for taller passengers, especially in the roomy Gran Turismo hatchback.

The BMW’s interior is elegantly styled, but its appearance is more reserved than some of the showier luxury small cars, like the 2018 Mercedes-Benz C-Class. Most surfaces are trimmed with quality soft-touch plastic, leather, and metal accents.

Standard seating features:

  • synthetic leather upholstery

Available seating features:

  • genuine leather upholstery
  • heated and power-adjustable front seats
  • heated rear seats
How Many Child Car Seats Fit in the 2018 BMW 3 Series?

The 3 Series has two full sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. The Insurance Institute for Highway Safety gave this setup the second-best rating of Marginal or the worst rating of Poor because some of the anchors are too deep in the seat cushions and difficult to maneuver around.

2018 BMW 3 Series Features

The 3 Series offers one of the best infotainment systems in the segment. Its standard 6.5-inch iDrive display has crisp graphics, quick responses, and simple menus. Functions are controlled using a knob on the center console, as well as with buttons on the dashboard and steering wheel. It may take time to learn the controls, but overall, the iDrive system is quite user-friendly. An 8.8-inch display with Apple CarPlay is available, giving you the ability to use your iPhone apps on the screen. This setup also adds a touchpad to the center console.

  • Standard infotainment features: a 6.5-inch infotainment screen, Bluetooth, a USB port, HD Radio, satellite radio, and a CD player
  • Available infotainment features: an 8.8-inch infotainment screen, navigation, Apple CarPlay, a Harman Kardon sound system, and wireless device charging
  • Additional standard features: dual-zone automatic climate control, keyless entry, and push-button start
