Used 2018 BMW M4 Convertible Trims Comparison

As you'd probably expect with a high-end two-door such as the M4, there's plenty of standard equipment. For starters, you get a turbocharged 3.0-liter inline six-cylinder engine (425 hp, 406 lb-ft) and either a six-speed manual transmission or an optional seven-speed, dual-clutch automatic. Also included is launch control, automatic rev-matching on downshifts, 18-inch wheels with summer tires, an adaptive sport-tuned suspension (a standard nonadaptive suspension is a no-cost option), an electronically controlled rear differential, keyless ignition and entry, dual-zone automatic climate control, leather upholstery, power front sport seats with heating, driver-seat memory settings and fold-down rear seatbacks.

In addition to the performance and cabin basics, the M4 has a decent amount of standard tech equipment, including an 8.8-inch display screen with BMW's iDrive infotainment interface, a rearview camera, a 16-speaker Harman Kardon surround-sound audio system, Bluetooth, navigation, a suite of smartphone and online applications under the BMW ConnectedDrive banner, HD radio and satellite radio, a USB audio input and a CD player.

A few key optional packages are available for the M4 as well. The Competition package ups the M4's power rating to 444 hp and adds 20-inch wheels, revised settings for the adaptive suspension, an even sportier exhaust and some interior trim upgrades such as M stripes on the seat belts. The Executive package adds full LED headlights, automatic high beams, side- and top-view cameras, an automated parking system, head-up display, and speed limit information.

Other options include 19-inch wheels, carbon-ceramic brakes, a heated steering wheel, parking sensors, blind-spot monitoring, a power rear sunshade (coupe only), a head-up display, Apple CarPlay and wireless device charging.

On the coupe, you get your choice of either a roof made of carbon-fiber-reinforced plastic or a traditional steel roof with a sunroof. The M4 convertible has a power-retractable hardtop with a wind blocker, as well as extended leather upholstery and door trim incorporating sun-reflective technology. When equipped with the Executive package, the convertible also includes front-seat neck warmers.
