BMW is also field testing solid-state battery tech
The BMW Group has fitted a BMW i7 with a solid-state battery as it charges ahead with testing of the next-generation technology.
In unison with tech partner Solid Power, the so-called ASSB pack (all-solid-state battery) uses cells that yield a higher density. However, they are smaller and lighter than those in current lithium ion batteries used today. So more energy can be stored in smaller packs.
This prototype uses existing prismatic cells in modules, rather than the more advanced bolted-to-pack cylindrical cells.
This suggests BMW could modify its current platforms to take the next-generation technologies. That means it could bring solid state batteries to market quicker than had previously been expected (2033).
Martin Schuster, BMW Group's vice-president of next-generation battery tech, admitted that SS tech could be implemented right now. However, the group's main focus was to continue the development of existing lithium-ion techology. He added there was still plenty of potential there.
But the new test mule shows the group is hedging its bets. Schuster said BMW has a 'technology-open mindset.'
He added 'We are continuously advancing the development of new battery cell technologies.'
Solid-state batteries are considered the next big thing for EVs and important for their longevity. For they offer greater capacity and more range than similar-sized batteries used today. Without the need for external cooling, they are also lighter. And they are less susceptible to temperature variations. Critically, they charge more quickly.
Mercedes-Benz earlier this year claimed it was close to putting solid state battery technology into production.

2025 BMW M3 Competition Touring vs Skoda Octavia RS+ TSi Comparison
The performance wagon is an enthusiast's favourite, especially for those with more than just themselves to think about. It is practical, family friendly even, yet when the driver finds themselves alone, it delivers substantial fun. Unfortunately there aren't many options and most are reserved for the upper reaches of the premium Euro market. An example is the BMW M3 Touring. It's the first time the M3 has been served up with a bigger boot and this M3 is BMW's RS 4 foil. A pity that the Audi is between drinks; we drove the last of the current generation last year, so a direct comparison seemed pointless. Instead we ask: do you really need to spend six figures to get your fast wagon fix? Can something costing significantly less satisfy the urge? Such a machine does exist, and it's just been revised too. We are talking about the Skoda Octavia RS. We've had coupe, sedan and convertible M3s in times past, and finally now the Touring. You might be used to the angry beaver look of the latest M3 up front, but it's still ungainly. However, the look improves aft of the grille. The Touring is pumped out, its sculpted wheel arches encasing a wider track. The extended side skirts fill in the gaps, bridging the exaggerated front and rear aprons. You'll also notice the XL exhaust tips and the wee Gurney flap on the roof spoiler. Its multi-spoke alloys look menacing though are a nightmare to clean (a good punishment for naughty children). Under the hood lies a serious rendition of the 3.0-litre straight six. This has a pair of monoscroll turbochargers and creates 390kW, helped by 650Nm of torque. Teamed with all-wheel drive and a quick-shifting eight-speed auto, the Touring can supposedly hit 100 in 3.6 seconds. Typical of the M breed, there is a raft of set-up options; the transmission, suspension, steering, brakes and stability control can all be tailored, most through three levels of intent. And you can save your preferred combo to one of the two M buttons on the steering wheel, for quick access. The M3 gets a good stiffening with extra bracing and struts, and tauter suspension settings teamed with adaptive dampers. The all-wheel drive is variable in nature and blessed with a rearward bias. There's also an M differential out back to further enhance that rear-drive feeling. You can select 4WD Sport, which serves up even more drive to the rear, or switch off the DSC completely and then you're in 2WD. Then you can tune the M Traction Control to your liking, through 10 stages of intervention. Along with an onboard lap timer, there's the Drift Analyser to record the duration, angle and distance of your skids. All this fun does not come cheap, however, with a base price of $199,600. The Skoda doesn't have quite the firepower or such a long hardware list but it doesn't ask nearly as much either. The new model starts at $67,990, while the Plus variant is an extra $5k for upgraded seats trimmed in leather and better sounds. The engine department has had an update, the 2.0 TSI making 195kW here, with 370Nm chiming in as well. The RS runs with a seven-speed twin-clutch transmisison, sending the torque to the front wheels alone. Helping ground that output is the electro-hydraulic diff lock. This tempers torque steer and minimises spinning wheels when powering out of bends. With both a power and traction deficit, it can't hope to hold a candle to the hard charging M3, with a stated 0-100km/h time of 6.5sec, if you can get it to stick properly. Helping balance comfort and dynamics are adaptive dampers. Ride in the RS is set 15mm lower than in the cooking version. The revised Otavia also gets a style update with new front and rear bumpers (new diffuser and tailpipes at the back too) and blackened bits. It sits on 19-inch, aero-optimised alloys. Sure, it doesn't sound quite as exciting, but you could have two of these and still go on a lavish holiday for the price of the BMW. The RS can decode demon roads well. Switched into Sport mode, it dives into the action, and holds a line sternly through the bends. It does feel a tad digital however as the torque vectoring function is working to keep things tidy. With 'ESC Sport' engaged, this lessens the intervention of the stability commendants, the front-end unshackled and it's your right foot that manages the show. The RS can take corners at a decent clip, the wheels scrambling to lay the power down as you give it just the right amount of jandal, wary to keep the front from pushing too wide. Through the tighter, twistier sections, it is genuinely engaging, grin inducing. The brakes are decent too with good bite but also a delicate pedal so you don't upset the balance with errant weight transfers. Its steering is quick, while also advising on how hard those tyres are working. The twin-clutch is up and down the cogs quickly and smartly, the paddles there for show really. Its 2.0-litre pulls nicely from 3000rpm at speed, but it's no screamer, being well done by 6500rpm. There's a bit of a rorty note to its delivery but the tyre roar can challenge it at 100km/h on coarse chip. BMW's M3 Touring can charge through the bends in an even more furious manner, but is it a case of being too much of a good thing? It's seriously rapid, much of its talent going untapped without getting unhinged on road. But, when you do get the chance, this is a blazingly quick and talented machine. It has an outright grip advantage with wider tyres at each corner. Sure, it is heavier but with a balanced weight split, it turns in sharply. The helm isn't brimming with feedback but you know it will just stick. With its variable AWD and the M diff working together, you can feed the power in mid-bend and it claws its way around without a hint of pushing wide. And then you can be on the gas hard before the exit. With its rear bias, this helps it tighten the line, making it feel very neutral. And easy. The ride in Sport plus is intolerable, Sport better but still bumpy. The in-between setting for the trans is not quite sporty enough in terms of well timed downshifts while full attack mode is way too racy. So it can be better to paddle it along on the road. There's nothing much wrong with the response of the turbocharged engine. It really comes alive from 3000rpm and it revs quickly to just past 7000rpm, sounding distinctive and powerful through the range. The brakes are almighty, with a strong initial bite yet a tactile feel. The M3 Touring is an impressive performer, though a bit OTT for your drive to the beach house. Road noise can be intrusive and suspension vibrations are amplified here compared with in the Skoda. The Czech is also that bit easier on fuel reserves. It'll average around the 10L/100km mark for a mix of city and motorway miles, whereas the BMW is in the 15s. When drinking heavily, the Octavia got into the 13s, the M3 saw close to 20. The character of the M3 Competition will sit well with those that owned a modified JDM rocket in their youth. The suspension set-up sees the tyres chattering during u-turns, the diff gets a bit grumpy when cold and the brakes squeak. It sits low, the splitters and lower skirts look quite vulnerable, while the big alloys had already met the curb a few times before we had our time with it. The Skoda is preferable as a commuter. Its ride is sumptuous compared with the harsher BMW. And the M3 generates a fair amount of tyre roar even at 50km/h. Neither suffers from any real turbolag at town speeds, the BMW with a heap of low down torque, the Skoda brisk too. Each has quick and light steering, the turning circles about equal. The Skoda doesn't have quite the firepower or such a long hardware list but it doesn't ask nearly as much either. You Could have two of these and still go on a lavish holiday for the price of the BMW. The safety minders know their place, issuing precious few alerts, though the Skoda's lane keeping is more insistent. BMW's active cruise with its Assisted Drive feature is smarter too, virtually taking care of motorway cruising. There are more widgets in the infotainment realm, a better parking camera with a surround view, and more items on the spec sheet, as you would expect for the much greater ask. The Skoda has everything you really want though, the bigger 13-inch screen a bit easier to navigate than the old system. However, a few more buttons on the dash would be nice, while the voice help isn't as proficient as the BMW's. It's a snug fit behind the wheel of the M3, the driving position set deep. The seats are firm, overly so, though have excellent adjustment and are ventilated too. The M3's cockpit wears the sports luxury leather and carbon combo well. Skoda RS has a roomier driving position, the seats with more comfort about them yet they are no less effective in overall support. The Skoda is your more practical performance wagon. It has a larger boot, with a wider, longer load area. The width of the BMW's hold is limited by intrusive suspension towers. However the M3 is not impractical, still with 500L of space, and with a variable split folding seat back too. The opening glass hatch is a nice touch, a 'heritage' trait. The Skoda is more accommodating of people in the rear seats. It's tight in the back of the M3 Touring, the big sports seats up front robbing those behind of leg room, while three across is a genuine squeeze. Most definitely. It's a quick, fun-to-drive car that is also more practical and easier to live with. You get to enjoy all of its potential, the limits easier to access whereas with the M3 Touring, you'll have to try a lot harder. Yet there will still be those with the means that will just want the M3 Touring Competition. It is a weapons-grade wagon but requires you to put up with its much harder edge.

BMW M2 CS returns with more power and pace
The second-generation BMW M2 arrived in 2022 but there has been no Competition model, at least in the EU. Instead BMW has revealed the full-fat M2 CS. With powertrain and chassis upgrades and more aggressive looks, expect a hefty premium over the standard M2s $150k price tag. BMW has made CS versions of M2, 3, 4 and M5. Instead of the base M2's 353kW and 600Nm of torque, the CS should develop over 500bhp (at least 373kW) and 650Nm. This is via a retune of the twin-turbocharged three-litre straight-six found in the standard car. Power will head to the rear-wheels through an eight-speed automatic gearbox. It is unlikely to have a six-speed manual option, according to Auto Express. The car has been spied testing, but in final form it has a large ducktail spoiler that's integrated into the bootlid and a fresh diffuser. M2 CS also features a matt black front splitter, a carbon-fibre roof and gold-coloured wheels. Final bodyweight is unclear. Read our review of the BMW M2 here. In the cabin there are 'CS' logos and a carbon centre console. It comes with more encompassing front seats too and, likely as not, some track-focused driving modes. The CS will probably be a 'limited run' if the former example was anything to go by (just 2200 units globally).

2025 Mercedes-Benz G 580 Edition One Review
Modern electric vehicles usually share a few traits: sleek aerodynamics, a focus on weight-saving for efficiency and often a futuristic aesthetic to match their advanced drivetrains. But it seems Mercedes engineers thought, 'bugger all that' (or whatever the German equivalent is), and built the G 580 anyway. It's an all-electric take on the military-born Geländewagen. And we love them for it. The Mercedes-Benz G-Class has always been an automotive icon, first as a military-grade off-roader, and more recently as a luxury status symbol. Now it's entered a new era without losing its identity, the brand having kept all that is good about the vehicle – its cubic design, heavy-duty construction and off-road capability – while adding a huge battery and four, yes four, electric motors. We took this big white box for a spin; more about that later. Priced at a hefty $276,000 for the Edition One model (with a standard version coming soon at $231K), the G 580 is aimed squarely at well-heeled enthusiasts. Yet in the realm of six-figure luxury EVs, that ask isn't as outrageous as it sounds. It is a natural step up from the EQS 450, and around the same ballpark as the BMW iXM60 and i7. Yes, it is expensive, but they could have asked more. You'd be hard-pressed to tell the G 580 is electric at a glance. Mercedes hasn't meddled with the G's iconic silhouette. It's still a big, boxy brute with short overhangs, perched on a ladder-frame chassis. The form follows function for maximum approach angles and interior space. At just a bit over 4.5 metres long, it's not as gigantic as it looks; many modern three-row SUVs are much longer. The Edition One trim adds gloss black 20-inch AMG rims, black door handles, and subtle hints of blue (check the brake calipers and the rub strips along the flanks) to denote its electric heart. Our test unit was white – cue another fridge comment. There's no spare tyre hung on the rear door; instead you get a lockable 'G-Box' for charging cables. The overall effect is G-Class through and through;. It's chunky, retro and cool, with just enough EV-specific flair to set it apart for those in the know. Up front, the G 580 Edition One sticks with a traditional grille. Round LED headlights flank it, complete with LED rings and adaptive beams that can mask out oncoming traffic. Fender-mounted indicator lamps and exposed hinges give it that old-school charm and the doors still shut with a vault-like clunk. Being the first G-Class with keyless entry, you press a button and give the door a firm shove – it's like closing a safe. Slide into the G 580 and you're greeted with a blend of familiar G-Class ambience and new-age tech. The Edition One's cabin is draped in Nappa leather – a two-tone Silver Pearl/Black scheme with contrasting blue stitching and carbon-fibre accents. It mixes Mercedes' top-tier 'Superior' and 'Exclusive' design lines, making it feel every bit the flagship. The dash is thoroughly modern Mercedes, with dual 12.3-inch digital displays and MBUX interface but thankfully retains chunky vents and analogue toggles. There's even the classic grab handle for the passenger. For space, the G 580 is generous up front but a tad tight in the rear. That relatively short length means rear legroom is merely adequate. The cargo area offers just over 500 litres, expanding to nearly 2000 litres with the seats folded. Creature comforts are certainly not in short supply. The front seats are heated, ventilated and massaging, with memory settings and classic Mercedes door-mounted switches. Wireless charging, cooled or heated cupholders, a Burmester sound system, and ambient lighting round out the package. The MBUX infotainment system supports all the expected apps and features. Its 'Energising Coach' is a quirky touch for it plays music and massages you if it thinks you're drowsy. And then there's 'G-Roar', a synthetic V8-like sound that plays through the speakers. It's convincing enough to fool a passenger but can also be switched off for silent cruising. The surge is instant and relentless. In Sport mode, it feels agile for something so large – it really can dance for a big rig. Fire up the G 580 and you immediately sense this isn't an ordinary SUV. For one, there's nearly three tonnes of mass beneath you. Yet it proves remarkably easy to drive around town. Visibility is excellent, the turning circle manageable and a 360-degree camera makes parking a breeze. Ride comfort is plush with an underlying firmness. The G 580 glides over undulations but there remains a hint of that traditional G-Wagen jiggle. Body control is excellent and refinement solid. With four motors and a 116kWh battery, the G 580 puts out 432kW and 1164Nm of torque. Zero to 100km/h takes just 4.7 seconds. The surge is instant and relentless. In Sport mode, it feels agile for something so large – it really can dance for a big rig. Steering is numb but accurate, and the Edition One's performance tyres offer plenty of grip. Brakes (a mix of big discs and regen) inspire confidence. Motorway manners are also good. Adaptive cruise and lane assist are present but unobtrusive, and the ride is settled at speed. Wind noise is noticeable but not excessive given the shape. Of course, a G-Wagen must prove itself when the going gets rough. While we didn't head far off-grid, we have been off-road in the G 580 at a controlled test. Switching to Off-Road mode engages the full suite of traction aids. Each motor has a two-speed gearbox with a low-range ratio, and the G 580 has multiple drive modes and crawl control levels. With 250mm of ground clearance, short overhangs, and a 26mm thick carbon-fibre shield under the battery, it clambers over most things with ease. It can even wade through 850mm of water. The headline trick? A G-Turn. This allows the G to spin 360 degrees in place – one side's wheels rotate forward, the other side's back – activated with a paddle in a special drive mode. It's genuinely useful in tight trails and more than just a showroom gimmick. G-Steer also helps the big G pivot tighter by overdriving the outer wheels in a turn. It makes this 4×4 surprisingly nimble in tight off-road scenarios. With a De Dion rear axle and independent front, wheel articulation is excellent. Permanent AWD and power delivery to a single wheel help it conquer tricky terrain. The only limitation? Performance tyres and no tow rating – likely due to weight limits. With a big battery and brick aerodynamics, efficiency was never going to be a G 580 highlight. But Mercedes gave it enough juice to make it work. The 116kWh battery officially returns 23kWh/100km, for about 450–500km of range. Realistically, expect closer to 400km. Drive it hard or on the open road and usage can hit 30kWh/100km but most owners will charge overnight at home and use it around town. DC fast charging at up to 200kW gets you from 10 to 80 per cent in about 30 minutes. An 11kW AC wallbox at home will fully charge it overnight. The nav system can route via chargers, and the Mercedes me app handles charge monitoring and pre-conditioning. The Mercedes-Benz G 580 is, in a word, epic. This electric G-Wagen could have been a compromised tribute but it's not. It's the real deal. It combines classic G charm with cutting-edge tech. Performance is great, range is adequate, and the technology is awesome – all wrapped up in that unmistakable G-Wagen style. Where else can you find a vehicle that massages you on the motorway, then does a tank turn in the bush? Yes, most G 580s won't venture far off-road, but they could. Mercedes has electrified a legend without losing the plot. If you ever doubted an electric G-Wagen could be the real deal, this one sets the record straight.
