Delta 4×4 Gives 2019 Suzuki Jimny A Costly Paris-Dakar Rally Makeover

Cars Carscoops

The 2019 Jimny's rally-raid looks take inspiration from a Suzuki LJ80 that completed the 1982 race.
'German tuner Delta 4×4 has built an off-road-prepped 2019 Jimny that pays tribute to one of its illustrious predecessors, the LJ80 that was built between 1978 and 1982. More specifically, it’s an homage to a specific LJ80 that competed in the 1982 Paris-Dakar Rally in the hands of Delta 4×4 owner Josef Loder and Dr. Alois Schneck. Remarkably, the diminutive Suzuki completed the grueling event and still survives to this day, serving as a design inspiration for a special Dakar-themed fourth-gen Jimny. Delta 4×4 gave the modern-day Jimny a similar livery (sponsors included) as the classic model . Obviously, that’s only the tip of the iceberg, as the tuning company also enhanced the tiny off-roader’s all-terrain capabilities. Also Watch: New Suzuki Jimny Meets Legendary Toyota Land Cruiser Troopy In Off-Road Review The Jimny has been fitted with a 50 mm (1.96 inches) lift kit for an even more generous ground clearance, wider fenders and 8×16-inch Legacy Forged alloy wheels shod in 285/75 R16 Mickey Thompson Baja STZ off-road tires. The set of wheels alone costs a whopping €3,800 ($4,300), while the lift kit costs €990 ($1,120). The ride height can be increased by a further 30 mm (1.18 inches) courtesy of spacers but that will set you back an additional €850 ($960). The tuning package also includes an additional headlight behind the driver’s side mirror, priced at €390 ($440). For another €390, the company can also fit a bull bar tested according to EU pedestrian protection guidelines. Other parts that can be added include a roof rack (€900/$1,020) and a two-ton winch (€1,200/$1,360). Add it all up, and the tally exceeds €8,500 ($9,620) — roughly half the base price of a stock Suzuki Jimny . Guess replicating the original, and not keeping things affordable, was the prime objective.'

'PARIS (Reuters) – Boeing Co engineers are reducing the scope and duration of certain costly physical tests used to certify the planemaker’s new aircraft, according to industry sources and regulatory officials. FILE PHOTO: The Boeing logo is pictured at the Latin American Business Aviation Conference & Exhibition fair (LABACE) at Congonhas Airport in Sao Paulo, Brazil, Aug. 14, 2018. REUTERS/Paulo Whitaker/File Photo But the strategy could be at risk if regulators and U.S. lawmakers probing two deadly Boeing plane crashes require even more rigorous safety tests before certifying new aircraft as passenger-worthy. As Boeing kicks off the year-long flight testing process on its new 777X, its engineers will cut hours off airborne testing by using computer models to simulate flight conditions, and then present the results to the U.S. Federal Aviation Administration (FAA) as part of the basis for certification, according to two people with direct knowledge of the strategy. Reuters could not determine when Boeing decided to move forward with the plan to cut back on physical tests or the extent to which it planned to reduce them for the 777X. For Boeing’s proposed twin-aisle jetliner, known internally as NMA, Boeing’s Test & Evaluation group is developing the technology to replace costly and labor intensive physical safety tests used for decades – such as using machines to bend the wings to extreme angles and shaking the fuselage until it cracks – with computer modeling, according to three people with knowledge of the matter, including an FAA official. Such work for the NMA is in the conceptual phase, though Boeing’s goal is to expand “certification by analysis” as “extensively as they possibly can” to slash development costs, one of the people told Reuters. Doing so enhances a finely balanced business case for launching NMA, which would be the first aircraft fully developed in the digital age. Boeing spokesman Paul Bergman declined to comment on the company’s testing strategy for the 777X or the NMA, but said the planemaker was “looking holistically at our design and certification processes” following the 737 MAX crashes in Ethiopia and Indonesia, which together killed 346 people. “This includes participating in ongoing independent government reviews and establishing a new board committee to review our end-to-end design and certification processes,” Bergman said. When asked whether the FAA would allow Boeing to eliminate an array of physical tests for NMA and 777X, FAA spokesman Lynn Lunsford said the agency “makes determinations on a case-by-case basis, relying on data and decades of experience in certifying aircraft.” Current regulations allow planemakers to use physical testing and analysis to demonstrate compliance. Like the MAX, the NMA and 777X – which Boeing is racing to deliver in 2020 – are centerpieces in Boeing’s duel with Airbus SE and will influence how Boeing decides to manufacture and certify an eventual 737 MAX replacement. How quickly and at what cost the new planes are delivered to customers is critical to not just Boeing’s bottom line, but also the U.S. Congressional budget. In February 2018, Boeing CEO Dennis Muilenburg touted the company’s “streamlining certifications” effort at an industry conference, saying it was “an item we want to keep on the leading edge.” While Boeing declined to elaborate on what Muilenburg meant by “streamlining,” people familiar with the matter said it includes lobbying for more limited direct FAA oversight and expanding the use of digital analysis over costlier physical testing to show regulatory compliance. Like Boeing, Airbus and other manufacturing heavyweights are working to seize technological leaps in computerized engineering methods and tools that bridge the real and virtual world, and improve factory floor efficiency. Airbus declined to comment. Five people familiar with the matter said Boeing believes that new technology and decades of testing experience have rendered some physical tests redundant for demonstrating safety. For example, when vibrating a fuselage on an enormous platform to expose weaknesses – known as fatigue testing – the vast majority of the time the tool itself breaks instead of the airframe, according to a person with knowledge of past tests. Such work is costly and has reliably confirmed engineers’ expectations, he added. HURDLES The strategy to streamline plane certifications faces hurdles in the coming months as the FAA and other global regulators investigate whether Boeing’s processes are flawed after the MAX crashes, and as the Chicago-based planemaker seeks to reassure the flying public that its jetliners are safe. Teal Group aerospace analyst Richard Aboulafia said the probes may trigger push-back against digital certification, even if there is no evidence it is unsafe. “A headlong rush right now might not be best from an optics standpoint,” Aboulafia said. The FAA declined to speculate on potential post-probe certification changes, but said it will “consider any and all recommendations that might help improve the process.” Boeing’s internal review has uncovered nothing that caused it to shift its certification approach, Muilenburg and Boeing CFO Greg Smith told journalists in recent weeks. Under current regulations, Boeing employees act as the FAA’s eyes and ears and complete much of the detailed certification work. For example, as Boeing works to certify the 777X, engineers were catching glitches using a scaled-down cockpit mockup known internally as ‘airplane zero’ in a Seattle-area lab as recently as February. But an FAA official with knowledge of the matter said that Boeing has not issued reports directly to external FAA officials as of early this month. That contrasts with Boeing’s original 777 development in the 1990s, when the FAA required Boeing to build a cockpit replica to conduct tests designed to weed out safety risks lurking in the 777 designs, and granular results were reported directly to the FAA for months, the official said. Despite advances in computing power, some experts argue old-school physical tests are categorically better because they can produce unpredictable results, said one industry certification expert. “Test has changed for the company from being a place of discovery to being mostly to validate what we thought we knew,” said Rick Ludtke, a former Boeing 737 MAX engineer.

'How Close Are We to Self-Driving Cars, Really?'

'Chris Urmson helped pioneer self-driving car technology at Google before founding Aurora (which sells self-driving car software to automakers, and this week announced a new partnership with Chrysler and a new round of investment by Hyundai). In a new interview, Urmson \'says he expects that in about five to 10 years, Americans will start seeing robots cruising down the road in a handful of cities and towns across the country,\' reports Slate. \'It will be about 30 to 50 years, he says, until they're everywhere. \'I think within the next five years we'll see small-scale deployment. That'll be a few hundred or a few thousand vehicles. Really this is the, it's Silicon Valley speak, this is the zero-to-one moment of proving that the technology actually works, understanding how customers want to use it, convincing ourselves that -- and when I say ourselves, I mean as a society -- that these are sufficiently safe, that we trust them on the roadway, and that's that first phase.. [W]hen the technology actually starts to become scaled, then we can ask the question what have we learned, what are the ways that we can make this a little bit safer, a little bit incrementally more efficient, and that's what I think local and state governments and federal government would invest in infrastructure.. The statistic I heard was 30 percent of traffic in San Francisco is people looking for parking. I heard a more alarming statistic that was 80 percent of traffic in Paris was people looking for parking. So imagine you have automated vehicles that take you to a location, you hop out, then it just drives down the block and picks up the next person and takes them where they're going. Suddenly, you've alleviated a massive chunk of the congestion in a city. Similarly, if you look at the floor plan of a city today, somewhere between 30â\'40 percent of cities is dedicated to parking and roads. And so again, if you have automated vehicles operating as a transportation service, whether it's private or public transportation networks in the city, you don't need that real estate to be dedicated for parking. That real estate now can be recaptured, and it can be used for park space, it can be used for residential space, yeah, it can be used for mixed residential-commercial office space.. Certainly for urban centers, I think it's much more likely that this technology is a shared platform that people get on and get off. It's an even more convenient version of a bus or of a taxi service. Read more of this story at Slashdot.'
