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.

EarthCruiser adds a bigger camper option to its heavy duty pickup line

EarthCruiser is a camper and expedition vehicle company based out of Oregon that we've previously covered for its huge commercial truck-based machines. But they offer more than that, from drop-in campers for smaller pickups to heavy duty pickup conversions. The company's latest product is one of the latter, offering a larger camping area than the current EXD model. This new camper conversion is called the Terranova. The big differentiator between it and the EXD is the camper section, which extends over the truck cab on the Terranova. This means that bed space can be moved to above the truck cab, instead of having to use a convertible dinette. So less reconfiguring, and generally more usable space. One other major difference is that the EXD is only available for the Ram 3500 and Ford F-350. The Terranova is being designed for both of those trucks as well as the Chevy Silverado 3500. The EarthCruiser Terranova is otherwise very similar to other EarthCruiser models. The camper section is made of fiberglass and plastic, and the pop-up roof is insulated with foam. The curtains are triple-layered. The company says it can house four people. It comes with a freshwater tank and pump to help supply the kitchen sink, drinking water tap, bathroom sink and indoor and outdoor showers. There's also a cassette toilet. The kitchen features an induction stove top and small refrigerator and freezer. A fan system is standard, and air conditioning is optional. Power comes from a 400-aH lithium-ion battery. The Terranova isn't yet available. EarthCruiser is finishing up design and engineering, and it plans to have finished examples early next year. The company is taking reservations now, though. Pricing hasn't been announced, but an EXD runs between $220,000 and $265,000, and we would expect the Terranova to cost even more.

2020 Chevy Trax spied sporting design cues from the new Blazer

We saw spy shots in August for what we thought was either a redesigned Chevrolet Trax or new GMC subcompact crossover. At the time we were leaning Chevy. But after this latest batch of spy shots taken near GM's proving grounds, we're now thinking this one is the Trax replacement and the other one was a GMC. For one, the thin row of LEDs looks remarkably similar to the 2019 Chevy Blazer's LED strip. The additional light slightly below that is similar to the Blazer as well, leading us to believe that the next Trax will have a Blazer-esque front end. At first glance, this vehicle looks slightly larger than today's Trax with a much brawnier shape than the current blob-like design. The rear roof cladding could be hiding the same sloped rear window with spoiler hangover we see on the Blazer. Circling back to the other small GM crossover we caught testing, this one doesn't have those Blazer elements. The curved windshield and sloping roof are like those of the GMC Terrain, as are the horizontal grille bars. By contrast, the above car has a straighter windshield and a roof shaped more like the Blazer. One element that does seem to diverge from the new Blazer are the taillights, but they don't exactly look production-ready anyway. If we're right about this being the next Trax (and we're pretty sure we are) then this looks to be a more distinctive vehicle than what it will replace. The mirrors have left their awkward spot on the doors, and it's shaping up to be a much sportier looking crossover as a whole. This vehicle will most likely end up being a 2020 model year car, and if so, we would expect to see undisguised photos of both it and the assumed GMC version next year.
