Inside Line tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "IL Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test drivers. Enjoy.

The last time we drove the 2013 Ford Focus ST we called it the $24,495 BMW M3. And despite the fact that the 252-horsepower 2013 Focus ST is a front-drive turbocharged hatchback, that spin around the French Alps had us thinking BMW and not Mazdaspeed 3 or Volkswagen GTI.

But that was a preproduction European-spec test car in an unfamiliar environment. Before we could make a full analysis we'd need to experience the hot rod Focus ST on our own turf.

Ford didn't have one available for us yet, but a local dealer did. $29,185 later, we walked out with our new Long-Term Tangerine Scream 2013 Ford Focus ST. Then we hit the road to get it broken in. Five days later we finished the break-in and sent it immediately to the track.

Would we still be thinking M3, or would the numbers and on-track performance bring us back to a Mazdaspeed 3/GTI mindset?

60-0 (ft): 112

Handling
Slalom (mph): 69.1 (67.7 w/TC off)
Skid Pad Lateral Acceleration (g): 0.93 (0.91 w/TC on)

Db @ Idle: 45.6
Db @ Full Throttle: 78.4
Db @ 70-mph Cruise: 64.7
RPM @ 70: 2,650

Comments:

Acceleration: Not easy to launch, but not as hard as some FWD cars. Doesn't want to bog or coil like Mazdaspeed 3, but also doesn't leave as hard. Needs about 3,500 rpm and quick clutch engagement for best launch. Wheels spin partway through 1st, then hook. When executed properly, the shift to 2nd doesn't bog. Shifter is vague for this kind of use. Probably fine during daily driving (or even road course use), but not direct enough for drag-style shifting.

Braking: Softer pedal than I'd prefer, but stopping seems reliable. Some variation in distance, but no fade.

Handling:

Skid pad: Readily rotates off throttle, which allows complete freedom of line adjustment here. This car would be brilliant on a road course. Communicative and lively. Fun. Stability off yields best numbers here.

Slalom: Eagerness to rotate on the skid pad hurts this car in the slalom. Still, its manners are superb if you're willing to drive it hard. Best time in "Sport" mode. Tuned to rotate so don't bother turning ESC off. Stability control and suspension engineers tuned this car for drivers who understand.

How many import guys want to race from a dig against an AWD or RWD car

My car is an import.

When I went to the track I left off idle and just rolled into it quick after trying to launch and it bogging (in the wagon). Awd launches are tricky if you're still trying to be nice to your car :rofl:

tune numbers are coming in

So now that the Focus ST has been out roughly a month several places have completed dyno runs and they all are coming out roughly the same:

COBB (93 Octane, 530 mi):

COBB (93 Octane, 1085 mi):

FocusST.org (93 Octane):

SCT released the first official tune yesterday for the Focus. Below is the pre tune runs they did for the project.

Stock run data below 87 Octane. Note how Engine coolant temperature plays a massive role in end power output once you get to real world temperatures. Also note that Cat over temp is also to blame for the upper RPM power reduction.

All 3 runs were done back to back with ECT @ 206 degrees

I will contrast this in the next post with results from lower ECT's

3 more stock runs later in the day that define what occurs once you reach full temp.

Runfile 012 @ 145 degrees ECT
Runfile 013 @ 185 degrees ECT
Runfile 014 @ 196 degrees ECT

As temperatures increase COT kicks in and timing decreases.

Here is the dyno after the tune at 185F ECT

As stated in our calibration thread our 13 ST was purchased with one primary “focus” in mind and that was to get custom tuning jump started and available to all of us. We all know that will be the base platform needed to properly calibrate these vehicles from stock form to highly modified. Since last week we have had the only Tuned Focus ST on the planet.

A big thanks goes out to the whole team at SCT and Especially Chris Johnson for all of the hard work they have done to bring this together !!


Dyno :

SCT vs Stock Calibration Notes:

Same SCT calibration was tested on both 87 and 93....power is down about 15fwhp on 87 vs 93.

NOTE: SCT recommends 93 or 91 octane.

The big deal is the power gain when the car is "hot" and at normal drive temp (99% of your time)

Stock Boost Levels- Stock the ST will make spikes of boost around
21.5 psi and then holds between 20psi - 17psi, depending on the commanded torque.

SCT Calibration Boost Levels - SCT 93 Octane Calibration the ST will make spikes of boost around 23.5 psi and then holds between 22.5psi
- 17psi, depending on the commanded torque.

Air Inlet Temps are very good.....after 10 minutes of idle time and
7 runs in a row they climbed from 80F (run 1) to 110F (run 7).

Stock Speed Limit is 186mph

Stock Rev Limit is 6700rpm
SCT Calibration Rev Limit is 7300rpm

Torque Truncation has been eliminated

Now, the car remains an ANIMAL on the street after it has some heat in it.


Lazy man's view with synopsis -


Tune alone appears to be good for around 24 HP and 76 ft-lbs GAIN
185 degree thermostat alone appears to be good for around 13 HP and 29 ft-lbs gain stock
185 degree thermostat + tune appears to be good for around 36 HP and 83 ft-lbs gain - AMAZING


202 degree coolant - HP - 217 stock vs 241 tuned ----Torque - 240 stock vs 317 tuned
185 degree coolant - HP - 230 stock vs 253 tuned ----Torque - 279 stock vs 324 tuned

36/83 gain from a thermostat and tune! Why the F cant anyone tune my goddam Optima. I would assume a similar gain could be had.

The Focus is turbo isn't it? It's easy to pull power out of cars like that. That's why I can pull an additional 130whp out of my BMW, why the old 2.7T S4's get ridiculous gains, Ecoboost Taurus' etc. It's almost not fair.
