Hennessey's 1,000-hp Escalade-V Is Big, Loud, and Back for 2025
Cadillac has given the Escalade a mid-cycle refresh this year, endowing the fifth-generation model and flagship SUV with a new face at the top of the luxury marque's range. The facelifted models include the V-Series variant, the Escalade-V, which comes with GM's already potent 6.2-liter supercharged V8, combining outstanding power output with premium comfort.
But if 682 horsepower isn't enough, Hennessey Performance has brought back the wilder version of its high-horsepower Cadillac Escalade-V. Building on the foundation of its previous Escalade-V tune, the Texas-based tuner has unleashed a refreshed package for the 2025 model year, giving GM's flagship SUV a monstrous 1,005 horsepower and 882 lb-ft of torque.

Supercharged Mods, Ported Heads, and Red Valve Covers
Dubbed the H1000, this second-generation upgrade jacks up the power and transforms the Escalade-V into a proper hyper-luxury missile, with the 6.2-liter V8 as the starting point. But thanks to a raft of upgrades – including a high-flow supercharger system, ported cylinder heads, a custom camshaft, and a complete fuel and induction system overhaul – Hennessey has pushed the big SUV firmly into four-digit territory.
The list of hardware mods reads like a drag-strip cheat sheet: upgraded throttle body, upper and lower pulleys for more boost, high-flow catalytic converters, long-tube headers, an oversized heat exchanger, and anodized red valvetrain covers for some under-hood flair. Even lifters, push rods, valve springs, and valves have been replaced to handle the increased stress.
As with all Hennessey creations, every upgrade is backed by professional installation, HPE engine calibration, and up to 500 miles of road testing per vehicle.
The Most Unhinged Full-Size Luxury SUV On Sale Today
Performance development is handled entirely in-house at Hennessey's Sealy, Texas facility, including dyno tuning and real-world evaluation at the Pennzoil Proving Ground. Every Escalade-V that leaves Hennessey's shop is put through its paces and gets a serial-numbered engine bay plaque, a 3-year/36,000-mile warranty, and the necessary badging
Despite the outrageous performance, Hennessey insists the full suite of factory drive modes remains intact, keeping the Escalade-V as usable as it is fast. That means you can still float through town in plush comfort, or demolish unsuspecting sports cars at highway speeds. Pricing hasn't been disclosed, but it never is cheap when it comes to more oomph from the American tuner.
This isn't Hennessey's first Escalade-V rodeo, but the 2025 facelift gives the tuner a fresh canvas and new opportunities to push the envelope. And with over 1,000 horsepower on tap, this might just be the most unhinged full-size luxury SUV on sale today.

Silicon-Carbon Battery Tech Ends EV Range Anxiety — 10-Min 0–80% Charge
By signing up I agree to the Terms of Use and acknowledge that I have read the Privacy Policy . You may unsubscribe from email communication at anytime. View post: Mitsubishi's New 3-Row SUV Looks Perfect for Families: So Why Won't It Come Here? Ending Range Anxiety: Major Steps, Not the Finish Line Imagine charging 80% of your electric vehicle's battery in under 10 minutes and achieving over 400 miles on a single charge. Group14 Technologies' silicon-carbon anode material, SCC55®, promises substantial advancements in EV battery capabilities, addressing some of the key barriers to mass adoption by improving both range and charging speeds. 0:05 / 0:09 Volkswagen partners with CATL to improve EV battery tech Watch More Enhanced Energy Density and Charging Performance US firm, Group14's, SCC55® material boosts cell-level specific energy to approximately 330 Wh/kg—about 30% higher than the industry's best commercial graphite-based cells, which typically reach around 250 Wh/kg. Group14's development pipeline targets as high as 370 Wh/kg in projected larger-format cells, aiming for 2025 commercial release. For comparison, many current-generation EVs equipped with graphite anodes max out around 300 miles per charge; field trials with SCC55®-enhanced packs (75 kWh) reportedly delivered over 400 miles in comparable conditions. Fast charging performance is also notable. Under laboratory conditions, SCC55®-based test cells have demonstrated 0–80% state-of-charge in less than 10 minutes using high-powered (350 kW) chargers, whereas most of today's EV batteries require around 30 minutes for the same recharge window. It should be recognized that these ultra-fast charge rates depend on both battery design and high-powered charging infrastructure, which — while expanding—is not yet universal. Technical Foundation and Cycle Life Traditional lithium-ion batteries rely on graphite anodes, which offer a theoretical capacity of 372 mAh/g. Silicon, in principle, offers a much higher storage capacity — up to 10 times more — but is known for severe swelling and rapid capacity fade over repeated charge-discharge cycles. Group14's solution uses a patented silicon-carbon composite (SCC55®) that incorporates silicon in a porous carbon matrix. According to Group14, this design achieves more than 1,500 cycles at 80% capacity retention, comparable to the cycle life of the best NMC lithium-ion cells currently used in electric vehicles.

Sign up or sign in with Google Facebook Microsoft Apple By signing up I agree to the Terms of Use and acknowledge that I have read the Privacy Policy . You may unsubscribe from email communication at anytime. Manufacturing and Real-World Integration A practical edge for automakers is compatibility. SCC55® can reportedly be integrated into existing battery factories without significant retooling, and is compatible with popular cathode chemistries such as NMC, LFP, or LMFP1. The silicon-carbon anode improves gravimetric energy density and enables lighter packs — Group14 claims silicon-anode cells allow a 20% reduction in pack weight, translating to overall vehicle weight savings in the hundreds of pounds. However, independent field verification of large-scale integration and the full impact on vehicle-level weight is still in progress. High-conductivity anodes also deliver somewhat improved regenerative braking responsiveness and, based on initial pilot testing, more consistent performance in colder climates, since silicon's conductivity helps maintain voltage under load. These operational advantages require external validation as broader deployments roll out. Charging Infrastructure Implications The enabling of true 10-minute fast charging is primarily realized when using 350 kW DC fast-charging stations—still relatively limited compared to lower-powered plugs, but growing in numbers. Group14 projects each high-powered station could serve up to six vehicles per hour, tripling throughput over typical present-day capabilities. These benefits, however, remain largely dependent on continued expansion of ultra-fast charging networks and cooperation with OEMs. Cost, Longevity, and Market Outlook The shift to silicon-anode tech is estimated to carry a 10-20% battery cost premium at the pack level, offset in part by improved charging infrastructure efficiency and the ability to downsize battery packs for equivalent range. Despite higher initial costs, improved utilization and logistics may yield net savings for fleets and consumers in certain scenarios. The projected cycle life, now reportedly matching leading Li-ion cells, marks a key threshold for adoption—but long-term field data will be necessary to confirm this parity under real-world driving conditions. Conclusion: Closing the Gaps, Not the Debate Group14's innovations signal a significant evolution — not a final solution — to EV battery constraints. The silicon-carbon SCC55® materials address longstanding technical barriers to higher energy density and rapid charging without drastically sacrificing battery life or requiring wholesale manufacturing change. Transformative gains in range and recharge convenience are within reach but claims about 'ending range anxiety for good' should be tempered by realities of charging infrastructure, vehicle integration, and cost evolution. This technology is an important catalyst, but large-scale transformation will depend on cross-industry coordination, policy support, and continued technical progress. The promise is exciting and real for the EV industry as a whole, but the journey, ongoing. Watch this tech. About the Author Brian Iselin View Profile

Vorsteiner Just Made Lamborghini's V12 Supercar Even Wilder
BMW And Porsche Expertise Comes To Lamborghini This publication hasn't covered anything from aftermarket tuner Vorsteiner, at least not in a long time, so it may not be common knowledge how respected the company is. Before we jump into its latest offering, for the Lamborghini Revuelto, here's a quick and highly simplified history lesson. Vorsteiner was founded by Peter Nam, forging a reputation in the BMW world for producing beautiful wheels with an OEM+ aesthetic alongside high-quality carbon fiber aero and cosmetic upgrades. Nam is so obsessive about detail that when reviving the tuner's E46 M3 carbon fiber program on its 20th anniversary in 2024, only 103 packages were made as a nerdy nod to the remarkable horsepower-per-liter figure of the CSL that this suite of interior and exterior upgrades mimics. That kind of obsessive interest in excellence had already elevated Nam to the next plane by 2017, when he founded a little restomod company called Gunther Werks, named after a German-born American, Pad Leader Günter F. Wendt. He was the last earthly individual astronauts saw before blasting off from Kennedy Space Center on Mercury, Gemini, and Apollo missions (among others). This symbolizes the link between Stuttgart's 911 as a base and California's GW as the mission. In a nutshell, the people at Vorsteiner know what they're doing, so this new Lambo kit will fit as well as if it were made in Sant'Agata. Five-Piece Carbon Kit Promises Multiple Improvements Vorsteiner says these parts don't exist just for appearance's sake. At the front, a wraparound spoiler is claimed to improve front-end downforce and a carbon hood reduces weight, though Vorsteiner admits the vents are only cosmetic. The massive vents on the lighter carbon fenders, however, are functional, channeling wheelhouse turbulence up and out to reduce instability and lift. Behind the front wheels, new side skirt elements aim to clean air down the side of the supercar, and at the back, a new rear diffuser aims to offer even more aerodynamic benefit. We should note here that Vorsteiner hasn't made any specific claims as to how much weight has been shaved, nor any specific details on downforce, so any gains are likely minimal. Remember, this is a contemporary Lamborghini V12 flagship supercar, so there's not much to improve on without fundamental alterations. Reversible Kit Available In Various Forms The best part about Vorsteiner's Aero Package is that everything bolts on using the original mounting points of the car, so the whole kit can be uninstalled when it's time to sell the supercar, keeping the resale value strong. More pertinent at this stage is what these parts cost, all of which, including the depicted fenders, are finished in gloss carbon, so buyers will need to spend a little more at their local body shop if they want to tone things down with paint. Front spoiler: $6,995 Hood: $11,995 Vented front fenders: $9,995 Side skirts: $9,495 Rear diffuser: $14,995 All, the full kit costs $53,475 before ftment, and that's without completing the look with a set of wheels. Vorsteiner offers 17 styles in Revuelto fitment, with three different prices across those designs: $12,380, $13,180, and $14,180. These numbers aren't exactly pocket change, but when you've already spent no less than $608,000 before options, what's another 68 grand? About the Author Sebastian Cenizo View Profile
