What ever happened with that?

Im liking the motor in the new Sonata, the 4 banger twin turbo with 275hp and mid 30mpg.

I liked the idea of Hyundai's turbo 4 until I saw that the actual performance figures weren't any better than my 8-year-old Accord, despite a claimed power to weight advantage, a claimed torque advantage, and a gearing advantage. I think its pretty clear those motors aren't putting down the claimed power.

LOL, hasn't Hyundai been in hot water for this issue before? ;)

Have they? What methods can they use to "cheat"?

I certainly liked the idea of a clutched supercharger.

They just blatantly lied about the power output...a buddy of mine had a 2001 Tiburon and was asked to be part of the class action lawsuit but turned it down. He didn't really buy it for the HP rating anyway, so he didn't want to deal with the paperwork. I can't find the article, but Hyundai claimed like %40 more than actual HP on some trucks sold internationally, but car estimates were generally less than 10-15% higher than real. Still sleazy though...

Didn't Mazda have the same issue when the RX-8 came out?

Does you 8 year old Accord have all the additional air bags that the news Hyundia has? I though not.

I didn't know there was a lawsuit about it. Here is a news link

I am pretty sure they don't do it now, especially by looking at Gen Coupe's dyno report.

tons of genesis coupes (2.0T motor) have dyno-tested at 180hp and 220 lb-ft at the wheels, so hyundai's numbers are spot on compared to the crank numbers.

Heh. I can't speak to the genesis coupe in specific, but I'm pretty sure Hyundai didn't plunk down a $85,000,000 settlement for fun.....

Try again. It has EXACTLY the same air bag setup as the current Sonata. Dual front bags, front/rear side head bags, and front seat-mounted side bags. The only "safety" things the Sonata has that my Accord doesn't are stability control, EBD, TPS, and auto-headlamps, none of which add weight or improve the safety of the vehicle in an accident.

And since we're talking two cars that weigh almost exactly the same, I'm really not sure what point you were trying to make regarding Hyundai's suspiciously low performance.

As for the past, the Genesis V6 coupe has consistently performed far below its claimed power-to-weight, too.

If the turbo 4 can deliver on fuel economy, it will still be a compelling choice. Just not as compelling as if it could actually do the ~6.0 second run to 60 MPH it should have been capable of given their claimed power.

find out how many crash bars / reinforcing members it has solely for the purpose of dissipating energy in a crash.

modern cars will survive crashes that cars from 10 years ago could not.

Im resurrecting this thread, Im curious to hear what people think now. I still see no supercharged tau v8, though they did cram the regualr 5.0L in the genesis (Id still like to see the 4.6L super).

As for the 4 bangers, even if the true power output of their twin turbo 4 isn't as claimed I think it'd make a fun little car in the new Elantra (am I the only one?). The Sonata is to big and heavy...I think a sporty commuter would be good (veloster isn't a commuter, not really a sports car either...2 door, 3?). Why do they even have a 1.8L turbo when they have the 2.0L turbo from the Sonata?

I do like the look of the Sonata/Elantra.

I got a ride in my boss's new Kia Optima SX the other day, with the 270ish HP turbo 4. Despite the ~50 HP advantage, it felt slower than my 221 HP Fusion. The Optima is about 100lbs heavier, and I'm only going off of the butt dyno, but I was surprised when I wasn't blown away by the acceleration.

If I had to guess, I'd say it was putting out more like 170 HP at the wheels.

Saw the Genesis Type R with the 429hp V8 at a car show last weekend. While I applaud the the effort, I'm not sure what demographic will be buying it. The interior was quite bland, and way too full of plastic and not enough wood trim.
The Equus interior, by comparison, was spot on for its price bracket, with plenty of what the Genesis lacked. Heated, cooled AND a massager built into the rear seats ?? Wow .. :O

Gearing makes a big difference too, not just peak power rating to weight.

The Sonata 2.0T is about 1.5 seconds quicker to 60 than your Fusion, ~6.1 vs ~7.5, looking around the web. So, not even close. No Fusion is anywhere near as quick, as far as I can tell.

The Optima is a couple tenths slower, so still not close.
