Bloodhound SSC fires up Rolls-Royce jet engine for land speed record

RAF ST MAWGAN, England — Fizz, whirr, shriek, pop and silence ... It took several attempts to get the Bloodhound land speed record contender started for the first time on Sept. 28. On a bright and blustery day at RAF St Mawgan in Cornwall, in southwest England, the sense of occasion was palpable, if only the damn jet engine's blades would fire up. But the Rolls-Royce 20,232-pound-thrust turbofan wasn't going to give up its virgin status as a car engine easily. As driver, RAF pilot and current land speed record-holder Andy Green explained, the Rolls EJ200 is one of the most reliable military jet engines ever, but it's never been used before in a car. "I can show you figures of its incredible reliability," he said, "but every bit of its control software expects it to be in a Typhoon [fighter aircraft], and we have to keep telling it that it is in an aircraft, which needs some quick-footed work on the software."

Quick-footed indeed, as right there on the RAF St Mawgan runway, without a pizza or a Coca-Cola in sight, software engineer Joe Holdsworth performed a virtuoso piece of recoding on the engine's software to persuade it not to shut down in alarm at some low-level electrical interference it simply doesn't see in its normal aeronautical environment. Then, with just 20 minutes left of the team's running permission window, the remote jet starter cart shrieked, its air-delivery pipe bulged like an elephant's trunk blocked with a coconut and the massive turbofan spun, popped, emitted a polite ball of flame and smoked into life. No cheers or high-fives here; this is after all a British team. But there was clear delight from the 20 engineers attendant on Bloodhound. After three successful starts, Wing Commander Green leapt from the cockpit and Mark Chapman, chief engineer, pronounced that he was well satisfied and that the sight of a jet car surging gently against its arrestor cable and wheel chocks was awesome. "We knew it was going to take a couple of starts to get it running," said Chapman, who explained why the engine appeared so smoky at first. "This is an inhibited engine, so it was tested a couple of months ago at Rolls-Royce and basically filled with corrosion inhibitor, and you've got to blow that all through at the start.

Fastest and most powerful SUVs in America for 2022

Here in the United States, we enjoy power almost as much as we like our SUVs. Thankfully, we’ve got plenty of both. Traditionally, the most powerful SUVs source their massive horsepower and torque from some form of a V8. While thatÂ’s still generally the case, electrification comes into play more and more, whether itÂ’s mild-hybrid tech, a plug-in hybrid powertrain or, as is the case with the two vehicles topping this list, fully electric vehicles. As we enter the 2022 model year, letÂ’s look at the most powerful SUVs available.  Before we dive in, letÂ’s address the elephant that is waiting just outside the door. Due to supply shortages, Mercedes-Benz is shelving most V8 models for the 2022 model year. Some 2021 models can still be found in dealer inventories, but we wonÂ’t include them. With that in mind, letÂ’s dive into the list. 2022 Audi RS Q8 — 591 hp / 190 mph Read our review of the Audi RS Q8 The only Audi on this list is a hot little number, which we characterized as “an uncompromising option in a field of compromised options.” Powered by a 4.0-liter twin-turbo V8 (which seems to be a popular format in this list), its 591 hp and 590 lb-ft of torque get it scootinÂ’ to 60 mph in just 3.7 seconds, and on to a top speed of 190 mph. It even has the bragging rights of holding the Nurburgring lap record for an SUV.   2022 Rolls-Royce Cullinan Black Badge — 592 hp / 155 mph (limited) Read our review of the Rolls-Royce Cullinan This is one SUV where being a passenger might be more exciting than sitting in the driverÂ’s seat, thanks to over-the-top luxury — what do you expect from a car that costs over $350,000? The driver doesnÂ’t go unrewarded, though, with a turbocharged 6.75-liter V12 at their disposal. Thanks to the Black BadgeÂ’s software upgrade, it makes 592 hp and 664 lb-ft of torque to help get to its electronically limited top speed of 155 mph that much quicker.    2022 BMW Alpina XB7 — 612 hp / 180 mph Read our review of the BMW Alpina XB7 Alpina takes already impressive BMW vehicles and turns them into even more powerful, more luxurious machines. The Alpina XB7 improves upon the BMW X7 with a biturbocharged 4.4-liter V8 offering up 612 hp and 590 lb-ft of torque. ThatÂ’s good for a 4.0-second 0-60 sprint and a 180-mph top speed. Alpina also adds its own transmission and drivetrain tuning, upgraded suspension, exhaust and a whole slew of unique appearance touches.

2021 Rolls-Royce Ghost has a fascinating new part to make it one of the most comfortable cars in the world

One of the neat things about Rolls-Royce is the extraordinary lengths the company will go to for maximum comfort. It's like how supercar builders will look for every little advantage to make their cars a tenth of a second faster. On the 2021 Rolls-Royce Ghost, the company is employing something called the Planar Suspension System, a nebulous designation for the collection of systems and parts employed. Some are straight forward, such as the four-wheel independent air suspension, and the way the GPS and forward cameras inform what level of firmness should be employed on the road. But one part left us perplexed: the upper control arm damper. We spoke to Jon Simms, lead engineer for the Ghost, for more information, and now we have a better grasp on what it is and what it does. As for what it is, it's the roughly horseshoe-shaped object highlighted in purple in the above photo. The yellow parts are bumpstops, and it's mounted on the same joint as the upper control arm. And it turns out it's a pretty simple piece of equipment. It works very much like the harmonic balancer on the end of an engine. It's a weight with a rubber-y flexible hinge, and going over smaller bumps, it absorbs some of the extra vibration and movement from the suspension. Those bumpstops in yellow give the damper some extra purchase on the control arm, and they absorb impacts from larger bumps that may move the control arm suddenly so that the arm and damper don't bang into each other. This may seem like a pretty minor thing, but remember, Rolls-Royce and its buyers are out for maximum comfort, so there's reason to invest in ironing out every possible ride quality issue, no matter the size. And even if it's a minor improvement, that's not necessarily a bad thing. Simms told us that existing Ghost customers they talked to during development had one key request about the driving experience: "don't break it." So making sure that the new car was basically like the last one, but a bit better, would seem to be what customers would want. 2021 Rolls-Royce Ghost View 29 Photos The Ghost is the first Rolls-Royce to adopt this full suite of Planar Suspension System parts, though other Rolls-Royce models have had pieces of the system. And considering the fact the Ghost shares its platform with the Phantom and Cullinan, now, we wouldn't be surprised if later versions of those models pick-up parts like this damper. Related Video:
