Wonder if GM will 'design-out' that sitting ultra low peering over the dashboard/side/rear windows out of a letter box feeling the most recent marques featured. Far better car though IMHO than the equivalent Mustang but a reminder of the 'challenged' driver visibility that a '71-'73 'breadvan' Mustang had.

Late 2027 for Camaro and comes with the new 409CI, 6.7L engine that the 2027 Stingrays & Grand Sport has now
This engine also to be used in GM trucks and is a total new design of GM's V8 engines
Being American made in Mi where the 1953 Corvette engines were built
Notice the high compression it has
Not only are the Grand Sport models getting this all new gen 6 engines but so is the Stingrays
The LS6 will be made in Detroit and also be used on other GM models
In its 72-year history, there have only been five generations of Chevy Small Block V8.
Today, GM is proud to unveil the 6th, which debuts as the 6.7-liter “LS6” in the 2027 Corvette Stingray, Grand Sport, and Grand Sport X.
With 535 horsepower, it’s the most powerful base engine ever offered in a Corvette. Its 520 pound-feet of torque makes it the highest production torque of a naturally aspirated V8 ever. The LS6 is where the legacy of the Small Block meets the latest in advanced engineering.
This engine is steeped in history and packing the best technology GM has to offer.
She’s Real Fine, My 409
The “LS6” name has been used throughout GM history, first appearing on a 454-cubic-inch version of the Small Block’s big sibling, the Big-Block, and again in a 5.7-liter Small-Block used in the C5 Corvette Z06 and the original Cadillac CTS-V. Bringing back this name pays tribute to GM V8 history, while also referencing the 6th generation of the Small-Block itself.
The new LS6’s displacement in cubic inches is also the same as another muscle car legend: the 409. Giddy up, giddy up.
“We’re trying to recreate some of what worked in the muscle-car era,” says Mike Kociba, assistant chief engineer for the Small Block.
“We wanted a wide, high torque band, and high power. It feels like we’re bringing a piece of Americana back.”
The specs are mouthwatering:
• 535 horsepower @ 6,100 RPM
• 520 pound-feet of torque @ 4,600 RPM
• 6.7-liter displacement
• 13.0:1 compression ratio
• Kociba and the rest of the Small Block team made an interesting discovery when they first mapped the specifications for the LS6 they could make a bigger, more-powerful engine while also improving emissions and maintaining fuel economy.
• “Historically, when you make large, high-power, high-torque engines, there’s a penalty,” Kociba explained. “But with advanced controls, our new fuel system, and a higher compression ratio, we’ve been able to improve emissions with a larger engine.”
• That’s the benefit of having powerful digital tools to aid in engine design. You can trial more possibilities and, at times, effectively eliminate previous compromises.
• “We were going to make it ‘only’ 6.6 liters, and then we started playing around and realized that by adding two millimeters to the stroke, we get more performance without compromising anything else,” Kociba said. “In the past, we might not have explored that.”
• No Replacement for Displacement (Or Compression Ratio)
• Compared with the LS6’s predecessor, the 6.2-liter LT2, the bump to 6.7 liters comes via extending the stroke (the distance the piston travels up and down) from 92 mm to 100 mm. The bore (the diameter of the piston) remains at 103.25 mm, and just like 100 million-plus Small Blocks before it, the bore spacing (the distance between center of one piston to the next) of the Gen 6 is 4.4 inches.
• Compression ratio – the ratio between the volume of the cylinder at the bottom of the piston's travel and the top is 13.0:1. Automotive enthusiasts will know this is a very high compression ratio, and in fact, it’s the highest ever for a Corvette.
• The team wanted to beat the compression ratio of the legendary 427-cubic-inch L88 Big Block of 1967-1969, a V8 made specifically for racing. “That was 12.5:1 on leaded fuel,” Kociba says. “The only way we could pull off beating that today with unleaded fuel was with our advanced controls.”
• Of course, the high compression ratio of the LS6 provides power, torque, and character, but it also improves thermal efficiency. This is a measure of how much of the potential energy in a fuel is being turned into mechanical energy, rather than waste heat. In simple terms, the LS6 extracts more mechanical energy from the same amount of fuel than its predecessors.
The LS6 torque curve peaks (“peak” is used lightly, here, because we’re talking about a mostly flat line) at 520 lb-ft. Chevy claims that’s more twist than any other free-breathing production V8 ever made, and we’re going to put that statement to the test below, but the fact that it equals the first (LB7) Duramax’s which is a diesel with a turbo built for effortless torque-y towing torque rating means Chevy should be pretty confident in its boast.

Set to ride on the rear-drive Alpha 2 platform, the next-gen Camaro is set currently scheduled to enter production in late 2027 at the GM Lansing Grand River plant in Michigan, meaning that should go on sale as a 2028 model.
The facility assembled the last-generation Camaro, and currently produces the Cadillac CT4 (which will soon be discontinued) and Cadillac CT5.
The plant will also manufacture the next-generation CT5, confirmed by GM in October 2025, as well as an upcoming Buick sedan
Hope the 4 door model never gets out of the clay form

The back reminds me of the Z4 based Supra. Maybe it will look better in a different colour without the stripes, too many vertical contrasting lines on that one.
