Renault, Nissan, Mitsubishi announce 35 new EVs by 2030

Renault, Nissan and Mitsubishi are going all-in on EVs. The trio announced plans to release 35 new electric models globally by 2030, ranging from Japan-only kei cars to commercial vehicles, and they sketched out plans to develop next-generation solid-state batteries. The three carmakers will leverage the benefits of economies of scale to keep development and production costs in check. Many of the Alliance's models already ride on a common platform; the Nissan Sentra shares its bones with the third-generation Renault Scenic. Looking ahead, the plan is to build 80% of the cars in the group's global portfolio on common architectures. Renault, Nissan and Mitsubishi are massive companies with a wide lineup of models, so there is no one-size-fits-all solution. Instead, the strategy focuses on five basic modular platforms. CMF-AEV will be for so-called affordable electric cars. KEI-EV will be primarily for kei cars, LCV will underpin commercial vehicles, and CMF-EV was designed to underpin mainstream models including the Ariya. Finally, the CMF-BEV platform will underpin about 250,000 electric cars annually starting in 2024. These include the production version of the retro-styled 5 Prototype introduced in January 2021, at least one car assigned to the Alpine brand, and a replacement for the Micra (previewed above) that will be engineered and built by Renault. Most of these cars will be equipped with a lithium-ion battery pack; that's likely going to remain the best way to power an electric car in the coming years. However, Nissan has been tasked with developing solid-state battery technology that promises to greatly reduce charging times. A solid state battery is tentatively scheduled to enter production by the middle of 2028, though it's too early to tell which model(s) will inaugurate it. Digital services will play a significant role in the Alliance's future lineup as well. By 2026, Renault, Nissan and Mitsubishi plan to connect 25 million cars to their cloud and over 10 million vehicles fitted with "autonomous driving systems" (a vague term that wasn't defined). All told, these investments will cost the group at least ˆ23 billion (around $26 billion at the current conversion rate) in the next five years. What does this mean for America?

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

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.
