2015 Ecoboost Mustang vs 2015 BMW 435i

[M.Senger]

My worst case scenario for EB:
Curb weight: 1490KG
Power 310 BHP

0-60: 5.3s

Best case scenario:
Curb weight: 1405 KG
Power 335 BHP

0-60 4.9s

It's just a calculation made in http://www.torquestats.com/modified/index.php?pid=calculator

We just don't know how much lighter the EB will be and you can put more torque than power in turbo engines. For example Ford Focus RS had 301 BHP and 324 lb-ft of torque. Even if 2.3L EB Mustang will have 310 BHP it can have 330-340 lb-ft of torque.

I've sinced revised my hopes/expectations to a more realistic 4.6-5.0 sec 0-60. Assuming 320hp/310tq/~3450lbs

I think a 5 second flat 0-60 time is about as optimistic as you can get here.

Assuming those numbers, the Ecoboost has a 10.8 power to weight ratio. The current GT's are in the 8.7 range and it's been reported to run a 4.5/4.6 0-60.

In order for the GT to match the power to weight ratio of the Ecoboost numbers your thinking, you'd have to drop its HP to around 345hp - a loss of 75hp. Losing 75hp would really kill the current GT's 4.5/4.6 0-60.

I can't see it being in the mid 5 second range, the current V6 does that on a bad day. Magazines have tested and gotten low 5 second 0-60's. Hopefully the Ecoboost will be lighter and have more hp/tq. Not likely by a lot, but every bit helps. I'm sticking with my 4.9/5.0 second guess.

You are trying to suggest, that a 2.3 will be nearly as potent as the 5.0 GT ..? (0~60 in 4.5s)



What are you basing these wild speculations on..? Are you trying to use the BMW engine, as a benchmark for the ford engine..?

I hope you know BMW lies about the ACTUAL horsepower of the 435i. The N55 puts out more than 300/300.. and it torque curve is flat & long. Do you know anything about engines.. let-alone cars?

The 2.3l in the Mustang will do 0~60 in over 5 seconds. Again, most likely close to the mid to low 5's.


Lastly, why are you making such wild claims of HP from a 2.3..? Ford said it will have more than 305hp...

I'm not sure why you act so butthurt as if i've personally attacked you.
The 2014 Mustang V6 is capable of 5.5-5.8 sec 0-60. This is known. Now take that and add in the your own guesses/figures from the new engine. For me that's 15 more hp and 30-40 more lb-ft tq. Have that torque available earlier, from 1500 rpm rather than at 4,250-4500 rpm. Lower the weight 50-100lbs, stiffen up with an all new suspension, better aerodynamics, better weight distribution, improve the auto slightly/improve the manual with launch control, and "don't leave too much performance on the table" with a better default factory tune than ever before. If Ford gets all of that done it's not too hard to imagine coming off with sub 5 second times. I'm just saying it's possible and that's what i'm personally hoping for. If not, i'll just shrug, understand my expectations were high and nevertheless be excited as a kid on Christmas for a test drive.

I want to see the EB s550 run a low 13 (13.2-13.3) in the 1/4. It will be funny seeing 4cyl mustangs dragging 5th Gen ss Camaros down the track with a tune/bolt ons.
I think we should see low 12's (12.1-12.2) for the new gt with the right power/weight. As far as driving dynamics and handling that is yet to be seen. BMW and Porsche were targeted for driving modes during s550 development. The hot rod first ride impressions seemed lackluster but I'm hoping that the first drives/tests will prove the Mustang to be a supreme handling car. If we could see .98g's for the ecoboost and just over 1.0g for the gt pp on the skidpad, these cars could be direct competition (performance wise) for the 435i/m4.

 

[M.Senger]

A lot of sources are claiming that s550 will be "400 lbs lighter" than s197. For Ford it is best to compare EB weight vs Mustang GT not the V6 to get those "400 lbs". Hyundai genesis 2.0 T weights only 50 lbs less than 3.8L V6.

https://www.hyundaiusa.com/genesis-coupe/specifications.aspx

Current Mustang GT weights 110 lbs more than V6 version. So looking at the weight of the engines only. V6 is 110 lbs lighter than V8, 2.0T give us another 50lbs less than V6 so it's 160 lbs. 400-160= 240 lbs. I think that this is the weight of the chasis that Ford have saved.

You use an engine that has 315+hp in the 435i.. (rated @ 300hp/300tq) with posted conservative 0~60 numbers...
...then.. facetiously claim the little 4cyl, 2.5 liter engine will be pushing 320hp... based on the "claimed" 300hp from the 3.0 6cyl BMW..?
When ford themselves claim "just over 305hp".




Why play around with the HP #'s like that^?
This thing will have soooo much torque down low, that it will make the v6 & v8 look laboring..

The 2.3-eb will probably have 312ft-lbs of torque @ 1,700rpms ~ 5,600rpms. The manual will probably be quicker than the auto.. @ 0 ~ 60 in 5.3s

Also.. some of those 0.02's come from the tranny refinement.. you seem to suggest ford has made leaps with transmissions. BMW wins every time.



But none of that matter now, it is now about how well can u drive the s550 chassis, not what another 50hp will bring.

It's nearly impossible that that kind of weight was lost. The car is pretty much the same size, bigger actually in some measurements.

The 400lb weight loss wasn't from any credible source. The upgrade to IRS and the inclusion of more options/tech already increase weight. You aren't going to see the Ecoboost weigh less than a C7 Corvette.

I think Ford will be hard pressed to get the Ecoboost under 3450lbs.

If I had to guess where each model would fall here is what I'd say. (Magazine numbers, I'm sure perfect track conditions and a good driver would best the 1/4 mile numbers).

Mustang V6:
Power - 305hp/280tq
Weight - 3525lbs
1/4 mile - 13.7 @ 101mph

Ecoboost:
Power - 315hp/305tq
Weight - 3475lbs
1/4 mile - 13.4 @ 103mph

GT:
Power - 440hp/400tq
Weight - 3600lbs
1/4 mile - 12.4 @ 114mph

 

[M.Senger]

Ecoboost:
Power - 315hp/305tq
Weight - 3475lbs
1/4 mile - 13.4 @ 103mph

Twin scroll turbo will give more tq than hp for sure.

Twin scroll turbo will give more tq than hp for sure.

Tell that to the Hyundai Veloster Turbo and Sonata 2.0T, they didn't get that memo apparently.

Mustang gt vs BMW 435 ...

Mustang gt for the win.

Performance styling and of course pricing,

Buy American as well.

He was not talking GT.. but the 2.3 eb.

I own a BMW 335i. Once a BMW is out of warranty, BMW=Break My Wallet. German cars are crazy expensive to fix. For that reason alone, I will go with the Mustang GT :-)

Test drove a 428i coupe today. Sweet car, very competent engine and auto and fast enough for my taste. I just really don't like the dashboard design. Looks wise it's nice but the Mustang beats it hands down. I'm just going to have to be patient I guess.
