Ford Falcon Sprints: the engines

Ford Falcon Sprint engines

In the lead-up to the release of the Falcon Sprints, there was plenty of media speculation - including from us at MOTOR - about just how far Ford would go for these last hurrahs.

On paper, the answer is not very. After all, the XR8 Sprint offers just 10kW/5Nm more than the car on which it’s based, while the XR6 Sprint makes 15kW/11Nm more than the old FPV F6; useful increases, but hardly game-changing stuff.

Start to dig under the skin, however, and you’ll find that, particularly in the case of the XR6, there is more going on here than initially meets the eye.

Ford -Falcon -XR8-Sprint -rearAs with the suspension tune, it’s the XR8 that has changed least, purely because as the newer car it has benefitted from more recent development.

Under the bonnet is the locally-built and developed 5.0-litre supercharged ‘Miami’ engine that was introduced with FG Mk II FPVs in late 2010. While power and torque have increased only slightly, the Sprint engineering team installed a number of measures from the 351kW FPV GT F.

Most of these measures are aimed at improving drivability, like the twin pedal map, which adjusts the throttle blade angle independent of accelerator pedal position. Sprint Program Manager Justin Capicchiano: “There’s a lot that’s gone into [the XR8 Sprint] just to make it drive nicer; if you drove the cars back-to-back, you’d notice the difference.”

Ford -Falcon -Sprint -engine -plateFord has also quoted power and torque figures for the ‘transient overboost’ function for the first time. Capicchiano says that “ordinarily, on a normal day, you’ll be in overboost all the time” which equates to a whopping 400kW/650Nm.

The overboost function lasts for 10 seconds, however it resets on every gear change so as long as temperatures are under control - i.e. you haven’t just done 10 laps of a racetrack - your Sprint will be making maximum power from rest all the way to the limited top speed of 230km/h.

“When we were doing GT F we said 15 per cent [extra power]; in reality, it was a little bit more than that,” explains Capicchiano. The same overboost function in the XR6 Turbo Sprint lifts outputs from 325kW/576Nm to 370kW/650Nm, making it the most powerful six-cylinder engine Australia has ever produced by some margin.

Ford -Falcon -XR6-Sprint -carbon -intakeCapicchiano and his team went to town on the venerable 4.0-litre ‘Barra’ engine. Despite very similar outputs to the FPV F6 motor, the Sprint unit is actually based on the regular XR6 Turbo engine, albeit with a whole lot of F6 parts - intercooler, turbo, injectors - bolted on.

The XR6T engine was chosen for its higher compression ratio, which in conjunction with the Aussie-made carbon fibre air intake and free-flow exhaust essentially means there is more power, everywhere.

“[The Sprint] is making a lot more boost earlier [than the F6],” says Capicchiano. “More boost in the mid-range - at 3000rpm it’s making 3psi more than the F6 was - and more of it at the top end.” Little wonder Capicchiano is happy to go on the record as saying the Sprint’s engine is “the best in-line six we’ve ever done”.

Ford -Falcon -Sprint -heroThere are gear-specific boost maps (the F6 just ran one boost map), launch control makes its first appearance in a six-cylinder Falcon and the six-speed automatic’s shift pressures have been recalibrated for crisper gear changes.

All this should make the XR6 Sprint the fastest Aussie Ford ever produced, though it’ll have to battle its eight-cylinder sibling for the title.

While there will always be critics saying Ford could and should have done more, you have to say the engineering team has done an impressive amount with the resources available.

Just how good a job, we’ll find out shortly when we drive the Sprints.

  • The XR6 Sprint is going to go like a scalded cat with those power and torque figures. The F6 did 80 to 120 km/h in 2.7s with 310 kw/560nm so with 325/576nm expect to see an improvement. Wish I could afford one! An FG XR6T with some upgrades is very tempting...something like the Premcar XR6T.
  • Xr6 turbo fkin beauty
  • Have sprint xr6 on order. Engine No 56. 56 years of ford engine in Aus and year I was created.
  • Power to weight ratios for the two cars taking into account overboost? That'd be interesting.
  • Bring it to America! We will gladly take it off your hands.
  • The article states: "While there will always be critics saying Ford could and should have done more, you have to say the engineering team has done an impressive amount with the resources available". That is an understatement by miles! (kilometres!). If all this translates through to reality come May/June, as I'm sure it will, then this small passionate Ford Aust team will deserve and should get international accolades for what it has achieved with this 'relatively old' platform using just the smell of cash left in an old banking bag! . My XR6 Sprint will be white and in my hot little hands come June. Can't wait. From other reports the Sprint suspension is at least as good as the 'more up to date' Redline Commodore and the handling will be like no other Ford ever. This XR6T wundamotor will no doubt be a collector piece and we can now thank the Ford team for wrapping it up and presenting it to us in the best Falcon ever created in 56 years by the 91 year old company. . This car will be truly a fitting send off for a car and manufacturing team that has literally helped build Australia for near 6 decades. Take a bow Sprint team. I can't thank you enough for taking an interest and making this car come true. I never got that modern GTHO I had hoped for since 2005 but, in retrospect, this XR6T is even more fitting because it has THAT motor. I am just in awe of what such a small dedicated team has produced. Thank you!
