Chevrolet planning new crossover between Equinox and Traverse

Chevrolet is taking a crowbar to its crossover lineup so it can slide in a new entry between the Equinox (shown) and the Traverse, according to a report in Automotive News. The current Equinox, a tweener compared to its rivals, will get smaller when the next-generation vehicle moves to the Delta platform that underpins the Chevrolet Cruze. The next Traverse will remain full-size, the liberated space between it and the smaller Equinox making room for a fourth offering from the brand. Designed on a short-wheelbase version of the Traverse platform, AN's sources say it will offer three-row seating, and its architecture will also serve the Cadillac SRX successor, the XT5, and the redesigned GMC Acadia. Yes, the Acadia will also come down a notch in size. Once all the rationalizing is complete, the Trax, Equinox, new crossover, and Traverse would give consumers a quicker, easier way to compare size and features with the competition. As it stands, the Ford Edge, Nissan Murano, Honda Pilot, and Toyota Highlander are all larger than the Equinox. The future offering and its two- and three-row seating options would take clear aim at those four vehicles, and the Equinox could focus on the Ford Escape, Honda CR-V, Toyota RAV4, and Jeep Cherokee segment. The new Chevy is predicted to go on sale at the end of next year as a 2018 model. Related Video: Featured Gallery 2015 Chevrolet Equinox View 14 Photos News Source: Automotive News - sub. req.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

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.
