The Toyota bZ4X and Subaru Solterra haven’t been particularly popular EVs, and their popularity may be about to wane a little further, with a new lawsuit concerning faulty batteries being filed in the U.S. Eastern District Court of California. According to a report by Road & Track, the 12-volt battery that runs the accessories (not the drivetrain) of these EVs is claimed to repeatedly fail, with the plaintiff who filed the suit saying that his bZ4X has required numerous battery replacements in just 5,000 miles of driving.
Toyota, Subaru Knowingly Sold Faulty Cars, Lawsuit Claims
Although this is a class-action lawsuit, concerning all bZ4X and Solterra EVs from the 2023-2025 model years, the court documents focus mainly on the plaintiff’s claims, arguing that the Toyota and Subaru were both aware of 12V battery problems before the cars went on sale, and that they failed to warn customers or fix the problem.
“The 12-volt battery in Plaintiff Wade’s vehicle has been replaced twice since March 2023,” reads the filing on CarComplaints.com, with the owner saying that the first failure occurred just weeks into ownership and the second when it had roughly 2,000 miles on the clock. The third reportedly happened around 5,000 miles.
Not The Only Owner On Record With Issues
Toyota
Another owner (this time with a Solterra) told the NHTSA that they had had the car since December 2024, and that they got the car new on a lease. “I have had the car since December 2024; the car was a new lease,” said the complainant. “The battery has failed twice – once in January, and again last week. When I took it to the dealership, they said they replaced the battery, [but] the new battery is now doing the same thing.” Other accounts have been posted on Reddit since early 2023, but the lawsuit does not claim to know what the core defect is, so determining Toyota and Subaru’s culpability may be difficult. Hopefully, the updated and renamed Toyota bZ and its Solterra twin don’t face the same troubles.
While I don’t want to sound like a tourist guide recommending all the popular sites in Stockholm, with summer approaching, there’s one location you should consider visiting if you find yourself in Sweden’s capital city.
Car meets are a rare occurrence in Scandinavia’s cold months, but with the arrival of spring and the clearing of salted roads, enthusiasts begin bringing out their cars. After a long, dark, and freezing winter, not one clear, warm day is wasted. While there are a few well-known spots for gatherings, on Thursday evenings over summer, Nifsta Gård is the place to experience the laid-back side of Swedish car culture.
The venue is home to Nifsta Classic Cars, which the Eriksson family purchased in 2016. Since then, it’s become one of Sweden’s largest American classic car dealers.
Initially, the meet-ups at Nifsta Classic Cars were limited to no more than 30 cars, nearly all of them American models. Today, however, the weekly gatherings are open to all makes and models, resulting in an eclectic mix of vehicles.
Organizer Mats Eriksson emphasizes that welcoming everyone – especially young car enthusiasts with their learner cars, known in Sweden as Epas – is essential for the growth of the Swedish car community. “The younger generation holds the key to preserving our car traditions, and I believe it’s important to include everyone, not just the old timers,” says Mats.
The Nifsta Classic Cars dealership focuses on American muscle cars, a tradition that dates back to the 1970s when Mats’ father started his own business. No fancy equipment was used back then, and that approach remains unchanged to this day, with Nifsta’s in-house mechanics taking a more traditional approach to repair and service work. Of course, European cars are catered for too.
Whether you are a fan of European models…
…Good ol’ Americana…
…Or have a taste for Japanese cars, there really is something for everyone.
This Corvette Stingray had a rather interesting front bumper conversion. What do you think?
Even the controversial Pilsnerbilar (beer cars) make the occasional appearance. If you’re familiar with Swedish car culture, you’ll know that these vehicles play a significant role. I can’t forget the bikes either.
And Sweden loves some big-rig action.
One of the standout cars for me was this 1969 Lotus Europa S2, which I found parked next to a 1981 Renault Alpine A310.
Another highlight was this Hillman Imp, which looked like it packed a punch.
The Nifsta Classic Cars meet is the closest thing we have to Daikoku PA, but instead of highways and a large parking lot, you’ll find small winding roads and a vast grassy garden.
There’s even a little café where live bands play during the latter stages of the meets. Who doesn’t enjoy a Swedish körv (sausage) in the peak of summer?
Throughout the evening, the cars keep coming and going, and those who stay long enough will often witness cheeky little skids on the road outside the venue. However, plans are in motion for a much-needed upgrade to the garden, and that will include asphalting the internal roads and creating a dedicated burnout pit so attendees can go wild.
I look forward to returning to the Nifsta Classic Car meet once the upgrades are complete. But I’m sure I’ll be back before then because the Swedish summer is just around the corner.
Corner balancing a car has been one of those things that seemed off-limits to the average automotive DIY enthusiast.
You can find a wide range of electronic scales from a speed shop like Summit Racing; however, a ‘decent’ set will set you back at least $1,000, and a higher-quality set will cost double that.
You can use the bathroom scale hack, where you jack the car up and lower it on a set of cheap bathroom scales. I even tried this back in 2020 with Project Rough, my ER34 Nissan Skyline GT-T, and had… moderate success.
To do this correctly, you must ensure you are working on a perfectly flat surface. The car needs to be as level as possible while on the scales – i.e., on some sort of platform – and you need a way to relax the arms after jacking the car up to move the scales into position.
It’s quite the dance, and there are a host of variables where things can go wrong. One of my scales broke due to going far beyond the maximum weight limit of 130kg (286lbs).
So, measuring the weight at all four corners, making any adjustments, and having to perform the whole circus again made this technique far from practical. It seemed like dedicated electronic scales were still the only viable approach.
Or Is It…
Fast-forward a few years, and I discovered a YouTube channel called SuperfastMatt. Matt’s videos are as humorous as they are insightful, and one called I Invented a Better Way to Weigh Your Car. And it’s Cheaper, Too. discusses how you can use leverage and a bit of math to calculate the weight at any given corner.
You have a supporting block in which a beam rests on. The supporting block is a ‘X’ distances away from the bathroom scale. You would then place the tire on the beam, and that weight transfers across the beam to the scale. The weight will be significantly smaller, which shouldn’t max out the scale. If you know the distance from the supporting block and the distance to the scale, you can calculate the actual weight with the value shown by the scale.
Seeing that I still had my analog scales from the first attempt and a workable platform I designed for aligning cars, I figured I’d let my inner engineer back out to play and give this a shot. Before going full send, I decided to test it on a small scale with an old battery from the family Honda Stepwgn.
I first weighed the battery to know my target— roughly 9.8kg (21.6lbs). The resolution on these scales leave a lot to desire.
I next created a platform that would have the beam level with the bathroom scale. I recorded the length (92.2cm). We will call this ‘L’.
Then I placed the battery on the beam and got a reading of 2.9kg (6.4lbs). Great! I’ll call that ‘Fa’ for now. Now, to calculate the distances.
Unlike the drawing, the force of the battery isn’t a single point on the beam, thus I decided to take the average of using a distance from in front of and behind the battery – one closest to the scale (L2) and one closest to the supporting block (L1). I would subtract the two and divide it by 2.
(L2-L1) /2 = Lm
(39cm-15.5cm) / 2 = Lm
11.75cm = Lm
With what I’m calling ‘Lm’, you can subtract that number from L2 and get the battery’s ‘center’ point of force. I’ll call this value ‘Lf’.
L2-Lm= Lf
39cm-11.75cm= Lf
27.25cm= Lf
With Lf now determined, I can divide it by the total length of the beam. If you know the distance relative to the beam, you can divide that number by the weight on the scale to calculate the weight. I know it’s getting a bit wild here…
Fl=Lf /L
Fl=27.25cm / 92.2cm
Fl=.2955
I learned this on the full-size test, but I tried to keep as many numbers after the decimal place as possible to increase accuracy. It does make a difference. With Fl, we can finally calculate the weight of F.
F= Fa / Fl
F= 2.9kg. / 2955
F= 9.81kg
This is an error of 0.10%, which more than proves the accuracy of this mathematical test. With this solid proof of concept, it was time to scale up.
Full Steam Ahead
With Project Rough ready to go, I decided to do an alignment, as I would use the same platform rig for the corner balancing.
For shaken, I had to reinstall some OEM parts, which threw my alignment out of whack.
Bringing the car to my house from its storage spot was one of the sketchiest drives of my life. I adjusted my laser level to level the platform with shims.
I was now ready to corner balance Project Rough. I got my bathroom scale out and ensured the beam and platform were level…
…And immediately ran into a problem. Although I had calculated that if my bar were 184cm long, I would have plenty of space to drive on the beam and not max out the bathroom scale, the weight deflected the beam so much that it touched the ground. Two extrusion bars weren’t going to work.
But how about three? Seeing that I had extra extrusions from various projects at that same 184cm length, I decided to try that before cutting the beams to a smaller size. I was still afraid that if I had cut the beams too short and driven too far on the beam, it would max out the scale, and I’d risk breaking them.
Even with three beams in place, they still bowed like crazy. This wasn’t going to work. I then remembered that I could move the scale closer to the car and use a wedge piece of wood for the beams to rest on to transfer the load, effectively shorting the length of the beams. All I needed to do was zero out my scale and try it.
With my current length (L) now shortened to 108.3cm from 184cm, the beam hardly deflected and could continue with the experiment. The reading on the scale was 42.5kg (93.7lbs) (Fa).
It was now time to calculate the various lengths as I had done with the battery. However, it was more difficult to tell where the contact patch was on the beam. I used a small square ruler and slid it under the tire until it couldn’t move anymore, and then marked the beam. I did this for both sides to get my L2 and L1 calculations.
(L2-L1) / 2 = Lm
(20.5cm-1.1cm) / 2 = Lm
9.7cm = Lm
It wasn’t until I finished measuring everything that I realized there was an easier way to determine the tire’s contact patch…
You can press a piece of flat scrap wood anywhere against the tire and mark out the L2 and L1 of the tire contact patch using the same method. Amazingly, this method matched my numbers for the front tires (9.7cm) but was slightly higher in the rear (10cm). These would be the Lm values used in the calculations.
Seeing that I can directly calculate Lm from the tire contact patch, my new equation is now this.
L2-Lm = Lf
20.5cm -9.7cm = Lf
Lf = 10.8cm
We now take Lf and calculate the force relative to the distance on the beam.
Fl=Lf / L
Fl=10.8cm / 108.3cm
Fl=.0997
Again, keep as many places as possible in the calculations. I stored the entire number on my calculator (0.099722992). Then, we can calculate the force of the car at that corner.
F= Fa / Fl
F= 42.5kg.0997
F= 426.18kg
And just like that, one corner is done! Next, roll the car back a bit, move the scale to the next tire, drive up, and crunch those numbers.
Once you get the hang of it, each corner takes about five minutes. Of course, if you have multiple scales and beams (I was still cautious and decided not to get more beams to do this), you could do this whole process in one shot.
Here are the values that I came up with after all the calculations. According to the shakensho, my Skyline should weigh 1,460kg (3,218lbs). I’m not sure how they got that number (wet, dry, full tank of gas, etc.), but I shouldn’t be too far off.
Factor in a super lightweight (read: slightly flimsy) FRP front hood, no spare tire, and a few other bits here and there, and the total calculated weight is pretty damn close. Ideally, I would take Project Rough to a place where I can drive and weigh the car, but that will have to wait until it’s passed its shaken inspection.
What can we do with this newfound information about Project Rough‘s balance? A corner balance shows your vehicle’s weight distribution, which can then be manipulated to optimize handling. For those who are dead serious about getting the best lap time, you would manipulate this distribution by physically removing weight or adding ballast in strategic locations to get closer to that ‘ideal’ 50/50 distribution front to back and left to right.
We can manipulate how much weight a corner receives by raising or lowering it. However, as one action affects all the other corners at the same time, it isn’t possible to change the front, rear, left, and right weight percentages. So unless I physically remove, shift, or add weight, Project Rough will have these values.
Front Weight % =54.06%
Rear Weight % =45.95%
Left Weight % =53.23%
Right Weight % =46.77%
Note: I didn’t simulate my body weight (84kg/185lbs) or disconnect the sway bars. In good practice, you absolutely should do this when setting up a race car or a car with incredibly stiff springs. Minor tweaks will have a bigger effect, and you don’t want accidental preload in the sway bars. Although Project Rough has adjustable sway bar end links, and I have dialed them in for no preload, it isn’t a race car. We are still doing this with bathroom scales regardless of how many variables we limit.
What we can do is get our cross-weight to an ideal 50/50 situation. Currently:
(Front Right (kg) +Rear Left (kg)) / Total Weight (kg) = Cross Weight %
(351.83kg+340kg) / 1439.27kg =Cross Weight %
48.07% = Cross Weight %
Anytime you have a cross weight above 50%, you have a wedge. Anything below 50%, like Project Rough, is a reverse wedge. Knowing this, you can follow these rules to adjust the ride height to get closer to a 50/50 distribution.
RAISING any one corner will INCREASE the weight on that corner and slightly affect all other corners.
LOWERING any one corner will DECREASE the weight on that corner and slightly affect all other corners.
Cross weight ABOVE 50% = DECREASE weight (height) on FR/RL or INCREASE weight (height) on FL/RR. – Wedge
Cross weight BELOW 50% = INCREASE weight (height) on FR/RL or DECREASE weight (height) on FL/RR – Reverse Wedge
Thus, I should work on increasing the height on the Front Right – Rear Left or decreasing the height on the Front Left – Rear Right. This is where everything becomes hella-tedious. You also need to decide how set you are in the vehicle’s ride height. Again, the stiffer the springs, the stronger the impact minor adjustments will make. However, if you are dead set on how the car looks, you might have to compromise that 50/50 distribution.
And that’s for you to decide. For me, once I get Project Rough back on the road, I will do this again and aim to get that 50/50 cross weight distribution. I also want to test a few more suspension projects and experiments.
This goes to show that if you’re not afraid of a little bit of math, you can unlock potential and data that would otherwise be locked behind expensive equipment. It did take some refinement, and this still won’t be as accurate as a good set of electronic scales, but unlike my first attempt at corner balancing with scales, it was a success.
Electronic scales would still be excellent, though…
If one thing unites certain automakers, it is that some claim ownership of a single English alphabet letter to name their high-performance division and their line of cars. BMW has the M division, Lexus has F, Volkswagen claims the R badge, and Hyundai has N.
Cadillac claims the letter V for the V-Series, and since its inception in 2003, its portfolio consisted of special Caddys that weren’t just boulevard cruisers; they made some properly fast cars. For instance, when the second-generation CTS-V came out in late 2008, it smoked its more expensive German rivals, the BMW M3 and M5, on the Nurburgring.
Today, its legacy lives on in special cars like the CT5-V Blackwing sedan, which has become a modern, supercharged symbol of American muscle, producing 668 horsepower from its C7 Corvette Z06-derived V8. However, the realities of real life, restrictive emissions regulations, and the advent of electrification have automakers tweaking their high-performance offerings. Mercedes-AMG is stuffing plug-in hybrid powertrains in its C63 and E53 sedans, and BMW’s latest M5 is being lauded as a heavy animal due to its electrified power.
New for 2026 is Cadillac OPTIQ-V, and as it suggests, it signifies that Cadillac is solidly in its EV era. Performance SUVs are a dime a dozen these days, but Cadillac’s latest electric beast makes a statement based on sheer numbers alone.
Underneath the OPTIQ-V’s skin is a dual-motor all-wheel-drive setup good for an estimated 519 horsepower and 650 lb-ft of torque in “Velocity Max” mode, which unleashes every last volt trapped in its wires. Cadillac says that with its launch control system on, the OPTIQ-V rallies to 60 mph in 3.5 seconds. On numbers alone, that makes the OPTIQ-V quicker than the previous Tesla Model Y Performance and even the Maserati Grecale Folgore.
To tame all that power, the OPTIQ-V comes with a picnic basket full of handling goodies, including standard Brembo front brakes, tighter steering, tuned suspension featuring ZF’s continuous damper control, and optional Continental SportContact 6 summer tires. Additionally, the car’s software also features a custom V-Mode (activated by an actual “V button” on the steering wheel), which lets drivers adjust performance features such as the steering feel, sound, acceleration, and a suite of traction management features to their liking.
Cadillac
Alex Doss, the lead Cadillac development engineer on the OPTIQ-V, said that from a handling perspective, the EV was a “spiritual successor” to the CT4-V sedan, and that it was developed as a fun, driver-focused “canyon carver” noting that they spent a lot of time testing it on roads like the Devil’s Triangle, Back of the Dragon, Tail of the Dragon, Hughes Road and Angeles Crest.
General Motors’ trusted Ultium platform is the electrical backbone of the OPTIQ-V, but unlike other vehicles powered by it, the OPTIQ-V comes with a built-in NACS (North American Charging Standard) port right from the factory. This enables direct adapter-free access to thousands of Tesla Supercharger stations, and on a full charge, the OPTIQ-V and its 85kW battery are rated at an estimated 275 miles.
The 2026 OPTIQ-V’s skin features enhanced exterior components that are as boy-racer as they are functional. The most noticeable features include the V’s redesigned front fascia, a signature V-pattern diamond-mesh grille for better airflow, a gloss black front splitter, and V-series badging throughout the vehicle. The OPTIQ-V also features exclusive 21-inch wheels finished in satin graphite or dark sport, a standard black painted roof, and a panoramic fixed glass roof. A carbon fiber package is also available, which adds a carbon fiber front splitter, rear diffuser, and rear mid-spoiler on the tailgate.
Royal blue detailing is a key feature throughout the exterior of the OPTIQ-V, shining on the royal blue brake calipers and royal blue-accented rear quarter windows. Exclusive to the OPTIQ-V are two limited-edition exterior paint jobs, including a matte-finished metallic grey color with warm highlights called Magnus Metal Frost and a special blue called Deep Ocean Tintcoat.
Inside, the interior of the OPTIQ-V blends Cadillac’s motorsports-inspired V-Series identity with a heavy technological-luxury aesthetic, featuring laser-etched badging, recycled sport fabrics, and real woven carbon fiber trim. Like the exterior, the color blue is a major design theme, as the OPTIQ-V’s two distinct interior palettes, a darker Noir or Sky Cool Gray, both feature Santorini Blue accents. Cadillac says this shade of blue “evokes the energy, action, and excitement associated with innovation and high performance.” Seatbacks and seatbelts finished in Santorini Blue are also offered as an option.
Cadillac didn’t forget to pack the tech in the OPTIQ-V. It features a massive 33-inch LED display, a 19-speaker AKG Studio Audio system with Dolby Atmos, and Google Built-in infotainment, which includes apps such as Google Maps and Google Assistant. Additionally, the car features a three-year OnStar subscription with Super Cruise hands-free highway driving and a suite of safety and driver aids powered by advanced radar, cameras, and ultrasonic sensors, such as adaptive cruise control, Blind Zone Steering Assist, Enhanced automatic parking, and Forward Collision alert.
Cadillac
Final thoughts
The OPTIQ-V really shows that Cadillac is very serious about its portfolio of EVs being the future of luxury. Alongside the Lyriq-V, it acts as the next chapter in a book dominated by the stories and lore of gas-powered icons.
Cadillac says that the MSRP of the OPTIQ-V starts at around $68,795 (including destination), and that it will be sold in the U.S., Canada, Mexico, and select international markets when production begins in Fall 2025.
At that price, the OPTIQ-V has some high-performance competitors, including the Hyundai IONIQ 5 N, which at $66,200, offers up to 641 hp, a 0-60 time of 3.25 seconds, and unique features like a simulated gearbox. Nonetheless, Cadillac sees this as a car built for a new type of Cadillac customer, but as we see it, Cadillac has been taking away customers from Tesla. Hopefully, this vehicle can help in their conquest efforts.
