BMW’s segment-bending X4 gets a M40i variant powered by a new 355hp straight-six

Following a leak, BMW has introduced the X4 M40i ahead of its public debut at this year’s Los Angeles Motor Show.

Enthusiasts fluent in BMW nomenclature can tell right off the bat that the M40i is a hot-rodded version of the segment-defying X4 that was developed to hit the track with input from the Munich-based car maker’s M division. The most important upgrades are consequently found by peeking in the engine bay, where the X4 gains a newly developed turbocharged, 3.0-liter straight-six engine that makes 355 horsepower from 5,800-6,000 rpm and 343 pound-feet of torque over a broad range that stretches from 1,350-5,250 rpm.

Bolted to an eight-speed automatic transmission, the six sends the M40i from zero to 60 mph in 4.7 seconds — roughly half a second faster than the 35i, the next model down in the X4 hierarchy — and on to an electronically limited top speed of 155 mph. A sport-tuned version of BMW’s xDrive all-wheel drive system comes standard, though the low-profile tires and a lowered suspension system greatly reduce its off-road prowess.

Outside, the M40i stands out from its tamer siblings thanks to a new front bumper accented by thin strips of chrome trim, a minutely redesigned rear bumper with a pair of round exhaust tips, model-specific 19-inch alloy wheels, and a sprinkling of M badges. All told, it takes a well-trained eye to tell the M40i apart from the aforementioned 35i.

The cockpit gets a M-specific three-spoke multifunction steering wheel upholstered in black leather, a M shift lever, new sill plates, sport seats for the front passengers and an upgraded instrument cluster.

The BMW X4 M40i will go on sale nationwide early next year, and it is expected to land in showrooms in time for the 2017 model year. Pricing information will be available at a later date.

The 10 best car battery brands in 2024
How to test a car battery

You must know this, but your car needs a battery to run properly. A dead battery means a car won't start, but various electronics in the car won't work properly either, including overhead dome lights, the radio, and even some security features, like door locks or alerts. So, it's in your best interest to ensure your vehicle's battery is in tip-top shape at all times. It's especially important if your car or vehicle sits unused for long periods. A trickle charger can help keep the battery powered in those situations, or worst case, a portable jump starter can help you get it going. But eventually, you're going to need to replace your battery, and it will help to know the best car battery brands out there so you know precisely what to replace your old one with. Let's discuss.
AC Delco
In operation for more than a century, AC Delco has been recommended as "the only batteries" for GM vehicles. You'll find them at retailers like AutoZone, O'Reilly Auto Parts, Amazon, and even some Walmarts. They're reliable, reasonably priced, and come with a good warranty, 18 months or above, depending on where you buy. A great AC Delco battery to call out is the Advantage series.

Bosch
Bosch is a solid mid-grade battery provider both in quality and price. They do have some affordable options, but their premium lines are still reasonably priced, with several tiers available for a wide variety of vehicles. The downside is that Bosch batteries are not carried by all retailers like some of the other options on our list, but you can find them online. You can also visit a Bosch service center if there's one near you. Callouts are the S4 to S6 series and the T4 to T6 series. We will say the brand's four-year free replacement warranty is unmatched.

Tesla’s fix for faulty Cybertruck pedal is simpler than you might think
Tesla Cybertruck

Less than five months after handing over the first Cybertrucks to customers, Tesla has had to recall the electric pickup to fix an issue with the accelerator.

In a notice issued on Friday, the National Highway Traffic Safety Administration (NHTSA) said that the recall impacts Cybertruck vehicles manufactured from November 13, 2023, to April 4, 2024. This suggests that all -- or almost all -- of the 3,878 Cybertrucks being recalled are those that have been manufactured to date.

Ford Mustang Mach-E 2024 vs. Mach-E 2023: What’s new in Ford’s electric Mustang?
Blue Ford Mustang Mach-E on a rooftop

The Ford Mustang Mach-E is easily one of the best EVs for the price, offering a solid range, sleek design, and pretty good tech on the inside. In recent years, it has gotten even cheaper -- thanks in large part to a price war between it and the Tesla Model 3. And, the company just took the wraps off of the latest and greatest version of the Mach-E, labeled as the 2024 model.

The 2024 Mustang Mach-E is notably different from the 2023 iteration in some meaningful ways. So much so that we decided to take a look at the two head-to-head -- to see if it was better to pay for the 2024 model or save some cash on any remaining 2023 stock.
Design
The Mustang Mach-E looks relatively unique -- in a good way. And thankfully, Ford has largely kept the overall design the same for the 2024 model, at least when it comes to the more consumer-focused models. The car retains the slatted taillights and crossover size. It also offers a large selection of colors, including the very blue Grabber Blue Metallic, as well as Rapid Red Metallic. It's a good selection of colors, and there should be an option for most buyers.
