I have an Emira on order - current expected delivery Q2 2023 (hopefully). I live at 7200' elevation in the US. What would be my expected power (torque) loss for the V6?
I believe the general guidance is that a supercharged engine loses the same proportional amount of power due to elevation as a naturally aspirated motor does. A Google search shows 3% power loss for every 1,000 feet of elevation gain. Turbocharged motors generally do not suffer from this loss as the turbocharger will just spin faster and compress more air to achieve the same intake manifold pressure. Based on this math, you should expect to lose 21% of the power, or 84hp. You can always overdrive the blower to spin a bit faster to offset this loss. The best way would be to dyno the car.
You have done a wonderful job once again (sad that for more comfort there is more weight...and so a USP has been lost) but you must undercut your Stuttgart friends by a significant margin even if you think you may have produced a match. Just one example: the packaging is once again compromised for touring. A hot sink at the back and an exposed opening behind the seats is not good enough. The engine layout is almost on its own responsible for all drawbacks. Lotus has failed to grasp this matter (pricing) till today and the numbers have shown...I just so wish you would find a way to do it to finally see numbers doing Lotus and its cars justice. Yes you may end selling a lot...SUVs that have nothing to do with Lotus strands for. Secretly I wish that instead of having grabbed the Merc blown 4 pot you had chosen the 2.4 four boxer from Subaru with a manual box! Packaging, layout, lower weight, lower centre of gravity, 3 pedals, better box...a dream with less power true but much more Lotus like.
When evija out?

I want the v6 in a dct and I'd be happy
Good joob :)
