Geely and Renault joint venture will develop internal combustion and hybrid tech

China's Geely Automobile Holdings and French car maker Renault SA on Tuesday said they will invest up to 7 billion euros ($7.71 billion) in a new equally held joint venture to develop gasoline engines and hybrid technology for automobiles. The JV is aimed at manufacturing more efficient internal combustion engines and hybrid systems at a time when the focus of much of the automobile industry has been on the capital-intensive transition to purely electric vehicles. "We are pleased to be embarking on this journey to become a global leader in hybrid technologies, providing low-emission solutions for automakers around the world," said Eric Li, Geely Holding Group chairman. The new company will employ 19,000 people at 17 engine plants and five research and development hubs, Renault said. At launch, it is expected to supply to multiple industrial customers including Volvo, Proton, Nissan, Mitsubishi Motors, and PUNCH Torino. The JV aims to have an annual production capacity of up to five million internal combustion, hybrid and plug-in hybrid engines and transmissions, Renault added. Reuters reported in March that the new venture will see 15 billion euros ($16.53 billion) in annual revenue. Saudi Aramco, which signed a letter of intent with Renault and Geely in March, is evaluating a strategic investment in the new company, Renault said. The Saudi oil producer has been involved in advanced discussions to take a stake of up to 20% in the JV, sources said earlier this year. Big oil firms have worked with automakers to develop sustainable fuels and hydrogen engines in recent years. But a deal here would make Aramco the first major oil producer to invest in the car business. The joint venture is expected to be launched in the second half of 2023.

Detroit 3 to implement delayed unified towing standards for 2015

Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer? What if the information you need is more difficult to come by, or worse, based on different standards for each vehicle? Well, in that case, you might be a truck shopper. For years, customers of light-duty pickups have had to suffer through different ratings of towing capacities for each brand. For 2015 model year trucks, though, that will no longer be a problem. According to Automotive News, General Motors, Ford and Chrysler Group have announced that starting with next year's models, a common standard will be used to measure towing capacity. The Detroit Three will join Toyota, which adopted the Society of Automotive Engineers' so-called SAE J2807 standards way back in 2011. The standard was originally supposed to be in place for MY2013, but concerns that it would lower the overall stated capacity for trucks led Detroit automakers to pass. Ford originally passed, claiming it'd wait until its new F-150 was launched to adopt the new standards, leading GM and Ram to follow suit. Nissan, meanwhile, has said it will adopt the new standards as its vehicles are updated, meaning the company's next-generation Titan should adhere to the same tow ratings as its competitors. While the adoption of SAE J2807 will be helpful for light-duty customers, those interested in bigger trucks will still be left with differing standards. There is no sign of the new tow standards being adopted for the heavy-duty market.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
