Porsche and Pixar Bringing Sally Carrera From "Cars" To Life

In September 2021 we covered a new "green gasoline" concept from Nacero, that involves constructing gasoline hydrocarbons by assembling smaller methane molecules from natural gas. Then in February 2022 the company inked a 20-year deal with NextEra to supply wind power to Nacero's Penwell factory in a bid to halve the lifecycle carbon footprint of its gasoline with the potential to take that number to zero. In so doing, the company claimed that the four million drivers burning Nacero gasoline will deliver the equivalent carbon savings of swapping 11 million ICE vehicles for EVs(!). We politely asked to see their math.NORCO, LA - AUGUST 21: A gas flare from the Shell Chemical LP petroleum refinery illuminates the sky on August 21, 2019 in Norco, Louisiana. Located about 10 miles up the Mississippi River from New Orleans, the plant agreed to install $10 million in pollution monitoring and control equipment in 2018 to settle allegations that flares used to burn off emissions were operating in violation of federal law (the Clean Air Act). Many of the coastal parishes in Louisiana have a long and ongoing history in oil and gas production, which is often at odds with concerns of environmentalists. (Photo by Drew Angerer/Getty Images)55-Percent CO2 Savings from the Production ProcessNacero's 93,000-barrels-per-day Penwell facility will earn a lifecycle (Scope 1-3) CO2 equivalent footprint* of 25 million metric tons per year. That's a 55-percent reduction from the 56 million tons that a typical crude-oil plant would be assigned for producing an equivalent amount. This is mostly because refining gasoline by cutting down super long and complex hydrocarbons from crude results in all sorts of other heavier, dirtier byproducts that you simply don't get when assembling gasoline from smaller methane molecules.*Scope 1 figures in direct emissions from sources owned by Penwell; Scope 2 is indirect emissions from purchased electricity, steam, heat, and cooling; and Scope 3 covers all other emissions associated with a company's activities (emissions from the use of the product, its transportation, waste generation and disposal, etc. ).8 Million Metric Tons Not IncludedOf that 25 million MT figure, 8 million are assigned to activities like natural gas extraction and fuel hauling, which are the responsibility of other companies who can claim credit for the carbon reduction they bring about, so to be conservative, Nacero's calculations do NOT include these savings. This avoids the potential for double counting them.Zeroing Out the Last 17 Million Metric TonsNacero uses four pathways to offset most of the remaining 17 million metric tons:Pre-combustion carbon capture and sequestration (1.4 million metric tons of Scope 1 emissions). This is accomplished using an absorber tower with a hot potassium carbonate solution that collects the CO2 that concentrates at the point where natural gas is converted to syngas on its way to becoming gasoline. Post-combustion carbon capture sequestration (1.5 million metric tons of Scope 1 emissions) A chemical solvent scrubs CO2 from flue gas generated by heater stacks employed throughout the facility, using existing, commercially proven technologies. The captured CO2 gets compressed and piped to a nearby oil field for use enhancing oil recovery, which sequesters the CO2 underground. Use of 100 percent renewable power (0.9 million metric tons of Scope 2 emissions) Here's where the recently inked NextEra deal for wind energy comes in. Use of renewable natural gas (11.8 million metric tons of Scope 3 emissions). The major sources of renewable natural gas today are landfills, animal manure, and solid waste extracted during wastewater treatment—all sources of waste that are continuously produced by present-day activities. Arriving at that 11 Million EVs Number…So to recap, there's 31 million metric tons of CO2 savings right off the bat from the refining process, plus at least 15.6 million metric tons from the four steps listed above. That's 46.6 million metric tons. The US Department of Energy assigns a typical gasoline vehicle a well-to-wheels pounds of CO2 Equivalent rating of 11,435 pounds, while an EV charged at the national-average electric grid's carbon equivalence gets a rating of 3,932 pounds. Using that math, switching just under 13.7 million gas cars to pure EVs across the country would save an equivalent amount of CO2. Nacero rounded down considerably to make its 11 million EVs claim conservative.When and How Much?Construction on the Penwell facility is just getting underway with a target of partially opening in 2025, making gasoline that warrants that 55-percent improvement over gasoline from crude. While the company has started arranging contracts for renewable methane, it's expected to take 10 years to source enough to fully eliminate that last 21 percent improvement. And a per-gallon cost is yet to be set for the gasoline but it's likely to be tiered. Nacero Blue gas is expected to be priced competitively with crude-based gasoline (the natural gas feedstock is way cheaper than crude), while Nacero Green will cost more to account for the added expense of sourcing renewable natural gas. Note that the gasoline may not actually be constructed of this gas, Nacero will simply contract to have an equivalent quantity of renewable natural gas injected into the national grid. 

cadillac ct5 Full OverviewCadillac's story in the two decades since the year 2000 has been one of chasing dreams. It went on a search for Art and Science. It traveled east to New York to find brand cachet and score modeling gigs. Like every carmaker, it pivoted wildly to crossovers and SUVs. Then along came EVs and the pledge that every Cadillac would soon be all-electric, all the time.Then there was V, the attempt to out-German the Germans at sport sedans. Like many of Cadillac's efforts in the past 20 years, it didn't quite pan out. But man, did the company ever get close, and the 2022 Cadillac CT5-V Blackwing is the proverbial going-out-with-a-bang car that should reverberate as one of the greatest American sport sedans of all time 20 years from now.The powertrain numbers are the pinnacle of Cadillac's gas-only power and performance: 668 hp and 659 lb-ft of torque from a 6.2-liter supercharged, direct-injected V-8. The engine itself is one of the last of the venerable LTs from GM's murderer's row of V-8s—the LT4. You get your choice of transmissions to pair with this aluminum-cast monster: an available 10-speed automatic or the standard Tremec six-speed manual.How Well Does the CT5-V Perform?For our instrumented test runs, we scored a manual-equipped version of the 2022 Cadillac CT5-V Blackwing. It also came with one significant performance upgrade, Cadillac's optional carbon-ceramic front and rear brake package ($9,000). Though our test team experienced some issues launching the car from a stop, the CT5-V (eventually) performed about as expected.In fact, our number from 0-60 mph mirrored what Cadillac called out in its own estimates, a 3.6-second run. But it didn't exactly come easy. We found it incredibly tricky to get the CT5-V to hook up, despite following Cadillac's extensive launch instructions, including bleeding the tires down to 35 psi, which helped.Our most experienced tester, road test editor Chris Walton, also had his hands full with getting the CT5-V to launch correctly and channeling the car's prodigious power to the pavement. It ultimately thundered its way to a best quarter-mile time of 11.5 seconds at 127.5 mph."I, too, struggled with the launch on this car," Walton said. "It's one of those 'you can't go to wide-open throttle until the very top of first gear or you roast the rear tires.' I tried automatic launch control first, then started tweaking the launch rpm and tire-slip knobs. After failures and some successes, I found one that worked on our testing surface: 4,000 rpm with 10 percent slip, which goes against logic, but it worked."The brakes were also a bone of contention with the test team. We recorded 102 feet to stop from 60 mph—a more than respectable number, especially considering the CT5-V Blackwing's 4,067-pound curb weight—but Walton wasn't exactly enamored with what he found when he pressed the slow pedal. "The brakes are OK," he said. "The pedal feels unnecessarily firm, making it difficult to modulate on the release into the skidpad." That said, the team reported that the carbon units held up well after repeated whoa downs from triple-digit speeds.Dynamic Numbers Are DynamicWe also had some trouble getting things totally sorted on the skidpad, but the 2022 Cadillac CT5-V Blackwing still put up some super numbers in the lateral-g and figure-eight departments, helped in part by a set of Michelin Pilot Sport 4S tires. Its 1.04-g average number is up there with the best sedans we've tested in recent years, and it matches that of the 2022 BMW M5 CS (interestingly, its CT4-V Blackwing stablemate performed a smidge better at 1.05 g).Out on our MotorTrend figure eight, the CT5-V Blackwing posted a 23.4-second lap at 0.89 g (average), with the M5 edging it at 23.2 seconds at 0.92 g. No, it didn't quite out-German the M5 dynamically, but for a front-engine, rear-drive sedan with a manual transmission (the M5 is all-wheel drive with an eight-speed automatic), the Cadillac is right there with it. That's duly impressive for a car that is in essence in its first and last generation. Yes, it's an evolution of the CTS-V, but the 2022 Cadillac CT5-V Blackwing is its own car, a Blackwing that can really fly.SPECIFICATIONS 2022 Cadillac CT5 V Blackwing BASE PRICE $84,990 PRICE AS TESTED $112,545 VEHICLE LAYOUT Front-engine, RWD, 5-pass, 4-door sedan ENGINE 6.2L Supercharged direct-injected OHV 16-valve 90-degree V-8 POWER (SAE NET) 668 hp @ 6,500 rpm TORQUE (SAE NET) 659 lb-ft @ 3,600 rpm TRANSMISSION 6-speed manual CURB WEIGHT (F/R DIST) 4,067 lb (54/46%) WHEELBASE 116.0 in LENGTH x WIDTH x HEIGHT 194.9 x 74.1 x 56.5 in 0-60 MPH 3.6 sec QUARTER MILE 11.5 sec @ 127.5 mph BRAKING, 60-0 MPH 102 ft LATERAL ACCELERATION 1.04 g (avg) MT FIGURE EIGHT 23.4 sec @ 0.89 g (avg) EPA CITY/HWY/COMB FUEL ECON 13/21/15 mpg ON SALE Now Show All Looks good!

audi s8 Full OverviewOur MotorTrend test team cycles through hundreds of vehicles a year, and an old pro like road test editor Chris Walton has been in and out of thousands of them during his career. So when he starts waxing poetic about a car like the 2022 Audi S8, you better believe we sit up and take notice."Wow. What a sleeper," Walton said of the S8 super sedan we recently had in for testing. "It's way too easy to find yourself driving 90 mph without noticing it. I could live with this car for the remainder of my life." That's a bold statement, Chris, do go on. "The whole thing kind of shrinks around you and makes it feel like an S6. Goodness, what an achievement this thing is."He's right, of course, about all the sleeping and shrinking 2022 S8 does. This particular car looks downright menacing, as well, thanks in large part to its Daytona Gray pearl paint scheme offset by a Black Optic Plus package ($2,100) that adds 21-inch, 10-spoke gloss black rims shod with summer tires, and other blacked-out elements including Audi's famed four-ring badge adorning (what else?) a bold black grille.There's also some menace in its exhaust note, a bombastic baritone that bellows out from its 4.0-liter twin-turbo V-8, which produces 563 horsepower and 590 lb-ft of torque. The engine is paired with an eight-speed automatic transmission that proved smooth and quick under hard acceleration. It all works in concert to move the S8's significant 5,204-pound mass with authority.Audi S8 0-60 mph Time: Very ImpressiveGiven its prodigious poundage, the 2022 S8's 0-60-mph time of 3.7 seconds is darn impressive. Its Quattro all-wheel-drive system and attendant sport differential certainly don't hurt matters when you're firing it out of the starting block, and the S8 also has a launch control feature that further aids the cause.The test team reported some issues getting the S8 to launch right—but when it does, it launches hard. "Because the window of optimal boost and rpm is brief, and if you miss it you must wait a bit before trying launch control again. But when everything works, you get neck-snapping acceleration. Very harsh shifts from 1-2-3," road test analyst Alan Lau noted.Audi S8 Quarter-Mile Time: Low 12s Will Do After hammering past the 60-mph mark, the 2022 S8 barreled its way to a quarter-mile time of 12.2 seconds at 113.0 mphagain, a heck of a number for a car of its size and class. It's hard to find an apples-to-apples comparison to the 2022 S8 given its curb weight and configuration other than maybe the BMW Alpina B7 xDrive or the last-generation Mercedes S63 AMG, as most of the 2.5-ton machines we've tested in the past few years are either SUVs or EVs.Interestingly, one of the closest EVs we found to compare the S8 against is another Audi, the dual-motor E-Tron GT Prestige sedan, which weighs in at 5,095 pounds. That car hit 60 mph in 3.6 seconds and on to a quarter mile of 11.9 seconds at 118.8 mph. Of course, the E-Tron doesn't get the S8's twin-turbo terror of a V-8, but you won't have to pay a gas-guzzler tax or live with the S8's officious inefficiency, either (it's EPA rated at 14/23/17 mpg city/highway/combined). Different power strokes for different folks.Audi S8: Getting Its Oversteer OnAs for the rest of the 2022 Audi S8's overall abilities, once again, with the "for its weight" caveat out of the way, its stopping distance of 105 feet from 60 mph is as impressive as its acceleration. Lau reported the following: "The brake pedal feel seems to be tuned with a good balance between comfort and performance. It's not overly touchy and easy to modulate. When it comes to very aggressive braking, they get the job done very well." Walton added that the brakes were "tremendous and easy to modulate to just stay barely out of the ABS" during his testing.But it was out at our figure-eight (24.4 seconds at 0.79 g avg) and skidpad (0.95 g avg) tests where Walton truly fell in love with the S8 and its capabilities. "The way it turns in makes it feel so much smaller and lighter," he wrote in his notes. "The steering is a bit vague in feel but very precise. The car takes a very neutral attitude, just barely dancing on oversteer. The way it drives off the corner with the all-wheel drive (the S8 also comes standard with a four-wheel-steering system) is phenomenal."Comfort, Plus a Whole Lot MoreSo yes, the S8 does things cars of its size, heft, and weight distribution (55/45 percent front/rear) have no business doing from a performance standpoint. But when it comes to its other mission as a cosseting luxury limo, all play and no relaxation can make for a bone-jarring bad time. That's where the S8's Comfort+ setting and its optional predictive active suspension ($6,000) come in to help smooth the road ahead. As with other systems of its type, the predictive suspension uses a camera to read the oncoming surface, sense jarring impacts or other undulations, and react accordingly to soften the S8's ride.In addition to the fancy active footwork, the 2022 S8 has all manner of standard and optional luxury trappings (this particular S8's black interior, trimmed with carbon accents, looked stealthy chic), as well as safety systems and other craftsmanship befitting a car that starts at $118,995 and rang up at $135,595 as tested.It's a car you won't see many of to begin with and one that you can be assured won't be around for much longer in its present configuration. It's a special sport sedan for a chosen few. So if you happen to be in the Los Angeles area and see one blow past you, it could very well be a certain MT staffer at the wheel (if he robbed a bank or raided his 401(k) to get one, that is). Be sure to say hi—if you can catch him.Looks good!
