In the more than three decades that MotorWeek has been on the air we’ve seen electric cars grow from homemade curiosities, to mass production icons. But, the public appetite for pure EVs remains stymied over range and cost. Both problems that plug-in hybrids are better able to solve. Still, most PHEVs haven’t been very exciting to drive. But what about this plug-in…the BMW i8… This futuristic concept car brought to life certainly looks exciting. So let’s see if it drives that way.

Looking like it just drove off the set of Buck Rogers in the 25th Century, comes BMW’s first take on an integrated plug-in hybrid, the 2015 BMW i8. It looks like nothing you’ve seen, yet somehow appears exactly what you’d expect an advanced hybrid from BMW to look like. 

Like everything else you see, the hybrid hardware is BMW’s own design and has both front and rear axle power sources that work both separate and together. 

Driving the rear wheels is a 1.5-liter turbo-I3. Yes folks, it has come to that, a 3-cylinder engine in a supercar. And, yes again, it’s the same engine used in the new MINI Cooper. Placed forward, with power for the front wheels is a more expected 96-kW electric motor that draws from a water-cooled 5.0-kWh lithium-ion battery pack lying low in the chassis. 

Working in harmony, they produce 357-horsepower and 420 lb-ft. of torque. And much like a traditional hybrid, a high-voltage starter/generator attached to the gas engine does double duty by feeding power back into the batteries. BMW claims that when in Sport mode, every mile you drive adds one mile of EV-range. Talk about having your fun and economizing it too.

The battery can also be charged on 110 or 220-volt circuits. 

While the power distribution is constantly shuffled between the axles, you can plan on strictly EV operation only if you take it easy on the throttle at speeds up to 75 miles-per-hour. Step into it and you’ll hear the internal combustion party start behind you.

You can also manually engage EV-mode. The government rates the range at 15-miles. But much like the Chevrolet Volt, you’ve got about a 300 mile range on just gas after that. 

Amazingly, BMW was able to keep the i8 iLooking remarkably like the original concept car, even retaining the scissor-wing doors and Carbon Fiber Reinforced Plastic passenger cell. With that and extensive use of other lightweight materials like magnesium and aluminum, the i8 weighs in at 3,285 lbs. 

Because of those doors, getting in and out can be a bit of a challenge, like many supercars; and yet another reminder that this car is much cooler than we are.

Once in, some found the seats very comfy, others not so much. But all agree the seating position is very low. Shorter drivers could not see over the nose which made tight maneuvers scary.

Navigation and most expected high-tech comfort and safety amenities are standard, and we applaud the use of familiar controls right off the BMW parts shelf. And that even includes the iDrive central controller. Also on the console are a simple electronic shifter, Driving Experience Control, and eDrive switch. 

Looking cool is one thing, but driving down the road the i8 is very cool as well. There’s plenty of engine noise electronically pumped into the cabin and it certainly doesn’t sound like a 3-cylinder. Engage Sport Mode and you’ll get a whole new level of responsiveness, both from the throttle and throughout the chassis. 

Transitions between gas and electric drive are fairly smooth, though there are times when getting real aggressive on the throttle results in the car taking a second to process where to send the power. But other than that, it’s a mostly seamless affair. Brakes are very touchy in the usual electric-drive manner. 

As for acceleration, with launch control engaged, we hit 60 in 4.4-seconds. There’s instant torque off the line and shifts from the 6-speed automatic transmission came in a hurry. Those shifts are very firm and quick, and had us thanking BMW for not succumbing to a CVT as we worked our way to the end of the ¼-mile in 12.9-seconds at a thrilling 110 miles-per-hour.  

The suspension is also a mix of something old and something new. The design is double-wishbone front and 5-link rear, but dynamic damping control and electric power steering are standard. Combined, they keep the i8 flatter than Kansas through the corners. 

Combined Government Fuel Economy Ratings are 28 MPG for gas-only driving; that’s about 20% lower than the Volt, with 76 MPGe for i8 gas-electric operation. We drive mostly in Sport mode and recorded 33.5. Our Euro-spec model prevented proper plug-in charging so we think owners will likely double our test figures.

We’ve certainly entered a new era of supercars. Lightweight, small-engine, electric-assist wonders that aim for high fuel economy just as much low 0-60 and lap times. And while the i8 is far from being the ultimate straight-line performer, its $135,700 price tag is only a fraction of the price of most other high performance plug-ins. 

So after driving BMW’s view of the future, we can absolutely say that the 2015 i8 will forever change the way you think about plug-in hybrids. And with cars like this, it’s clear that gasoline, electric, and high performance, can smoothly live together as one.

CX-50 Gets Higher Mileage With A Little Help From A Friend

Episode 4438

The CX-50 debuted for 2023 not as a replacement for Mazda’s CX-5 small crossover, but as a more deluxe option to be sold right alongside it. Well, that two-pronged approach continues today, only the CX-50 now gets a little something extra with help from an unexpected source.

This is the 2025 Mazda CX-50 Hybrid, which joins the CX-90 and CX-70 as a new member of Mazda’s “electrified lineup.” Now, where the 70 and 90 are both plug-in hybrids, the CX-50 is more of your traditional hybrid, Mazda arriving here with some help from hybrid pioneer and partner Toyota.

It’s a familiar story, as Mazda’s first small crossover, the Tribute, shared its hybrid powertrain with former partner Ford’s Escape. The CX-50 is built in the same Alabama plant as the Toyota Corolla Cross, but rather than using its hybrid system, the CX-50 actually uses the larger RAV4 setup with a 2.5-liter I4 engine and a combined output of 219 horsepower. Though probably for cost reasons the CX-50 stores energy in a nickel-metal hydride battery instead of a lithium-ion battery as in the RAV4. Like all CX-50s, all-wheel-drive remains standard, though here it’s electric motor only for the rear wheels along with an e-CVT.

Not much else changes from the rest of the CX-50 lineup, but the Hybrid does come with a slightly reshaped lower front bumper and unique wheel designs. Mazda was able to do some fine-tuning to the hybrid setup, so the experience is not exactly like driving a RAV4. That includes throttle response, which is a little more immediate, and unique drive modes. The RAV’s Sport mode is missing, but we think that’s actually the default setting for the CX-50.

Of course, the CX-50’s chassis is a willing companion no matter what’s working away under the hood, and clever packaging everything under the rear cargo floor keeps cargo capacity mostly intact. Rear storage space falls only slightly from 31.4 to 29.2 cu-ft, yet rear seat folded max capacity is somehow exactly the same at 56.3 cu-ft.

None of [it's differences from the Turbo] are really a deal breaker if you’re looking for a more efficient CX-50.

Working our way forward through the five-passenger cabin, the rear seat room is good, and seats are comfortable, while front seats are equally cozy with a great driving position and the typical Mazda sporty feel. Hybrid availability starts midway up the CX-50 trim ladder at Preferred, which comes with a 10-inch infotainment display and leather seating. Premium plus adds ventilated front seats and a head-up display.

At the test track, the CX-50 proved pretty quick off the line, taking 7.6 seconds to get 60, which is only a tad slower than the 7.2 seconds we saw in the CX-50 Turbo. Power delivery stayed consistent down the track, but it’s not exactly thrilling, as it is mired with a eCVT which seems to run afoul of everything Mazda stands for. We’re not particularly fans either with consistently high engine noise throughout the quarter-mile which we finished in 15.8 seconds at 89 mph.

Brakes, however, were strong and consistent, stopping in 110 feet from 60 mph. There’s not a lot of weight gain here compared to the Turbo, though it feels like it with slightly less urgency to turn in. And the Hybrid’s skinnier tires also worked against it when it came to grip level through the cones. Overall though, it remains solid-feeling and quite capable, and we say all of that just to note the differences, none of which are really a deal breaker if you’re looking for a more efficient CX-50. And if you’re not, stick with the Turbo.

Regarding that efficiency, Government Fuel Economy Ratings are 39 city, 37 highway, and 38 combined. We averaged a good 37.8 mpg of regular, which is almost 50% higher than the CX-50 Turbo we had as part of our long-term fleet last year. All making for a much better than average Energy Impact Score using 7.8 barrels of oil yearly with 3.9 tons of CO2 emissions. Pricing starts at $35,390 for Preferred; top Premium Plus comes in at $41,470.

Currently, Mazda is taking a wait and see approach when it comes to full EVs, having discontinued their MX-30 EV two years ago. But they continue to spread electrification throughout their existing lineup, which, as we’ve been saying for years, is a much better approach.

The 2025 Mazda CX-50 Hybrid is not necessarily a better CX-50 for all, as driving enthusiasts will still prefer the Turbo setup. But, it is a much more efficient way to go, one that sacrifices very little of the Mazda driving experience while delivering over 500 miles on a tank of gas.
