Also if manufactures are running a high current the LEDs need to be cooled somehow or they will melt.
Please don't use an Accord as the standard for LEDs. We are talking about luxury cars here. Does the Accord even offer LED headlights? I know LED DRL's are an option.

Meh, back to the RC….

is a turbo/supercharger almost a sure no in one of these cars within 1-2 years?

the 5.0L v8 was a monster in the isf. But the industry is now trending towards smaller efficient engines with turbos.

There is nothing fuel efficient about a TT V6. Might as well get a V8 if it's available.

If you really want a good MPG car look no further than the SOHC 1.8L Civic! Very good real world MPG with that car.

i'm talking more about horsepower to fuel consumption.

a turbo smaller v6 is no doubt more fuel efficient than the 10 year old 3.5L v6.

and a bigger turbo v6 is no doubt more fuel efficient than a 5.0 v8 at the same horsepower/torque.

EPA rated maybe. Real world, no. Turboed engine will likely to burn more fuel than 5.0 V8 if your right foot is heavy. Implementation of Cylinder deactivation on V8 "Like C7" will boost fuel efficiency on V8 much more than going to smaller engine.

TT V6 are the biggest guzzlers around, believe me. These things suck gas like a jet.

A 5.0L V8 can be pretty good on gas at light to moderate throttle. And at WOT they still drink less than a TT V6

This is why TT V6 always have their gears tuned to be on the highest ratio, stop start and other features to curb fuel consumption.

of course i'm talking real world where 90% of driving doesn't go past 4000 rpms.

lets not fool ourselves. going with a 5.0L v8 instead of a turbo v6 would be a bit old school... but reliability would be high because the design has been proven for so long.

the biggest knock against lexus is handling/driving feel. having a heavier v8 up front would not be a good first step in the right direction.

the RCF has been designed with a V8 in mind, hopefully. there is no excuse if this car comes out and its a nose heavy understeering pig...

Considering that the latest generation of Lexus cars, specifically the 3IS and 4GS are the best handling sedans in their class, I'm going to give Lexus the benefit of the doubt in this case.

Heavier? Perhaps so. But a TT V6 with the two turbochargers, plumbing and the inter coolers is all extra added weight.
Toyota even claims that the new 2.0t 4-cyl is heavier than the 2.5L V6 in the IS250!

Turbos V6 can be more powerful than V8.

But I agree that for the simplicity, linear power, no lags, better gas ...the Na V8 is better

That is why Toyota and Honda never really cared about going turbos.

The main points is that they want simplicity in maintenance and parts.

Also, TT v6 can only get so much more on after market boost....NA V8 gets waysss much much more with after market Turbo. No replacement for displacement

So you have driven this Accord in Australia to give us all feedback on LED lights? Maybe I missed that you did drive it in Australia.

@tigerstyle

That may be your opinion

But future Philippine buyers of the Lexus RC would all disagree with you

Lexus RC coupe to be launched in PH around August next year

Lexus Manila customers are demanding the V8 version

Lexus unveiled the all-new RC coupe at the recently held Tokyo Motor Show. Based on the GS platform, the RC gives the Japanese luxury carmaker a truly sporty model outside of the LFA. Let's just say it's a relatively "cheap" way to race a Lexus for those who can't afford to buy the aforementioned limited-edition supercar.

Now, Lexus Manila accompanied a few of its valuable customers to the show, and these Lexus owners were naturally smitten with the RC. Some of them, in fact, were already badgering company president Danny Isla for a unit, and virtually all of them are clamoring for a V8-powered RC. There's just one small problem, though: The RC, as you read this, isn't officially available with a V8 engine.

You see, when Lexus presented the car at the Tokyo Motor Show, only two engine choices were announced: a 3.5-liter V6 and a 2.5-liter in-line-four hybrid. Thing is, there has been unofficial talk about Lexus soon coming out with a V8 powerplant for the RC, and that the variant could appear at the North American International Auto Show in January. Likely to be shoehorned into the RC is the 416hp 5.0-liter V8 found under the hood of the new IS F--most probably tweaked to better serve the requirements of a sports coupe.

According to Isla, Toyota Motor Philippines president Michinobu Sugata wanted to bring in the V6-engined RC when the new car is launched in our market sometime August next year, but the TMP boss is now reportedly rethinking the plan after the Filipino Lexus owners have expressed a preference for the V8 version.

Also, an online poll was taken on the TGP website:

Current results as of December 6, 2013 ; 1:00 AM - GMT/UTC + 8

Which engine of the all-new Lexus RC coupe do you prefer?

1) 3.5 liter V6 = 31%
2) 2.5 liter inline-four hybrid = 23%
3) 5.0 liter V8 = 47%
FULL POWER BABY!!! GO ALL OUT!!!
