You cannot simply add the two HP figures between the ICE and the electric motors. So the 106 HP is what that engine is rated for. In tadem, the two engines can produce 191 HP. So given the instant torque of an electric I would expect it to feel more like a 200+ HP vehicle, though that isn't neccessarily reflected in a 0-60 time.

gotcha

but looks like every other makers have similar 40hp motor. so fusion is the only odd ball? or is there other hybrid which has 100+ hp motor? maybe this is why fusion has superior city EPA rating? don't know. but seems bit odd to me.

I could be wrong, but it could be how they report their #s.

The Prius also has a 100+hp electric motor and a like 110hp gas motor but only 138hp combined. I'm not sure how it all works but vehicles with bigger electric motors are much more efficient.

...only in city. On the highway, they are actually less fuel efficient. Exponential power curve requirement as speeds increases.

This is why Hyundai took a different approach as, according to NTHSA, 57% of driving done by Americans are on highways. They focused more of their attention on highway gas mileage, rather than city.

Hyundai is the only major manufacturer using a 6 speed auto transmission. All other competitors are using CVT. They replaced the torque converter with a 40kw electric motor directly fused with this transmission. It runs full parallel with the gasoline motor. That is why you can coast using electric power only at 62mph. I'm willing to bet this hybrid will be the fastest of the group. Its the lighest, with the most power and with discrete gears so you dont get bored or annoyed.

I know that styling is subjective. I, however, absolutely HATE the styling of the current/new Sonata.

There was absolutely no reason for that second mini grille ontop the hood. It looks like a tacked on brow. This ruins the whole look in my opinion.

reason they use 6 speed auto is that they dont have technology to have power split device like other manufacturers... meaning real life mileage will suffer.

I think you meant the Hyundai can CRUISE at speeds up to 62mph with electrical-only power....but can't accelerate in electric-only to/from there.

if that's the case, I hope the battery is powerful enough to sustain 60mph for more than 2 miles.

Incredible drag coefficient. Modern sedans have better drag coefficient numbers than many sports cars today.

Most sports cars need drag for better downforce in high-speed corners actually.

If I recall the IS250/350 sedan has better downforce and a drag coefficient of .27, so yes it's always a balancing act for total aero effect. Often the sports cars have larger tire/wheel combos with big contact patches impacting drag coefficient also.
