Tesla exec calls rival EVs 'little more than appliances'

Tesla's Vice President of Business Development Diarmuid O'Connell called the company's competition "little more than appliances" at the Center for Automotive Research's Management Briefing Seminars in Traverse City, MI yesterday. "In essence, [mainstream automakers] delivered little more than appliances," O' Connell said. "Now, appliances are useful. But they tend to be white. They tend to be unemotional." According to Automotive News, O'Connell's main critique is that vehicles like the Nissan Leaf and BMW i3 don't deliver enough performance or range to draw the attention of consumers outside of a small group. The solution, in O'Connell's mind, is more power, more range, more excitement and a lower price – that last point is particularly rich coming from an automaker whose cheapest current offering, the Model S 60, costs $66,000 – although the cheaper Model 3 is on the horizon, way out there, somewhere. But some EVs are better than none, O'Connell added. "On balance, I'm happier that [traditional automakers are] doing these cars than not," O'Connell said. "I just wish they would do them better and faster." O'Connell also used his appearance at the Management Briefing Seminars to launch a volley at the Michigan legislature, blaming its opposition to Tesla's direct-sales model for the lack of available EVs in the Wolverine State. "I think if the Michigan Legislature would allow Tesla to sell cars in Michigan, we could probably address [the lack of available electric cars]," O'Connell said. Related Video:

Rolls-Royce Cullinan and BMW 8 Series spied south of Death Valley

Recently, we've stumbled upon a number of manufacturer prototypes running around. Usually, spy photographers sit and wait for hours with cameras primed in order to get a few shots of a car. We just got lucky. First, we caught the new Chevy Corvette ZR1 convertible during a Facebook Live video. A week or so later McGraw snapped a video of a ZR1 coupe cruising in his neck of the woods. Today, our ace photographer Drew Phillips caught a BMW test fleet filling up the new Rolls-Royce Cullinan and 8 Series coupe in Baker, Calif. Baker sits along Interstate 15, about halfway between Los Angeles and Las Vegas. It's just south of Death Valley, and, being late August, suggests that BMW was doing some hot weather testing. Drew was filling up his car when the fleet rolled in. There were at least two of the new king Rolls and a single 8 Series. Both cars were wearing a full swirl camouflage wrap. It's not an uncommon place to see prototypes. Still, seeing a whole fleet roll in is quite a sight. We've seen official photos of the Cullinan before, but these pictures give us our best view of the profile and rear we've had so far. From a distance, it looks like a high-riding version of the new Phantom with a hatch in place of the trunk. The taillights are obviously just filler units. Expect the final version to look very much like the squared off LED units on the Phantom. Likewise the interior and engine should be straight from the Phantom. That means a twin-turbocharged V12, though power is likely to be sent to all four wheels. We've seen the full BMW 8 Series concept a few times now. The proportions on the production car look the same, with a long hood and even longer wheelbase. The nose isn't quite as aggressive as the concept, but we expected the styling to be toned down to meet crash and safety standards. As for engines, look for six, eight and (hopefully) 12-cylinder power under the hood. A plug-in variant is also expected. Both cars have been in development for a long while, so look for full debuts sometime this auto show season. Maybe we'll happen upon some more test mules between now and then. Related Video:

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.
