Easier Manual Gears: Block Downshifts

Lotus 98T Cockpit View at Monza.png
As modern race cars use automatic clutches and paddles on the steering wheel to change gears, the clutch pedal is slowly being phased out from many sim racing rigs. Even less have an H-shifter, and as a result, racing with a manual transmission is becoming a lost art. Most who try initially struggle on downshifts - but there is a technique that makes them a bit easier if you are trying to learn "driving stick": Block shifting.

Going up through the gears is relatively easy, even with a manual transmission on board of your virtual race car: Simply press the clutch and let off the throttle, simultaneously move the gear lever, then release the clutch and get back on the throttle pedal. Just like that, the next gear is engaged. Of course, this needs a bit of practice regarding coordination and timing, but it is rather straight foward.

Two Feet for Three Pedals​

It is not quite as easy the other way around, as downshifts take place in braking zones. Remember the two pedals you used for upshifts? Now you need to add the brake pedal to that - and with most of us only possessing two feet, improvising to operate all three pedals is a necessity. The technique to apply here is usually referred to as heel and toe, meaning you engage the clutch with your left foot while braking with your right (i.e. your toes), slightly pushing on the throttle when changing gears with your heel to match revs to the engine speed.

Once this technique does not cause you to slam straight into the closest wall because of coordination of movement needed, driving older race cars becomes a much more engaging activity. The good thing about this: Most racing vehicles from the days of manual transmission have rather long braking distances, and gearboxes usually only had four or five gears, giving racers enough time to downshift smoothly before corners.

Frantic Braking Zones​

Enter the late 1980s and early 1990s: As brakes became more efficient and gearboxes expanded to six and sometimes even seven gears, downshifts became much more frantic, especially in lightweight Formula cars. There is barely enough time to go down through the gears by the time you need to turn into the corner - unless you use block shifts.

While nowadays paddle-shift operated sequential gearboxes need to shift gears one after another, manual transmissions have no such constraint. This means that it is possible to go up or down multiple gears at once, which can come in very handy in situations like the one mentioned above.

Heel & Toe Gang 4 life :D

Comments

I didn't know this had a name. I just did this a few weeks ago in my team's 240SX. There are a few corners where I went from 4th or 5th straight to 2nd when I was ready to get back on the power. I'm not brave enough to try heel-toe in a real car, and my daily driver is automatic so I can't get much real world practice.
 
I want to see someone drive the mp4/6 in ams2 with a manual, that car is insane!
The MP4/6 should ofcourse always be driven with H-shifter and manual clutch :inlove:
Below not from AMS2 but here you go - myself enjoying it alot the only differ I feel is AMS2's flaws especially related to breaking/tyre modelling compared to rF2 as displayed here, but gearing/gas feeding/clutch handling more or less the same.

Enjoy! :)

Edit: ok wrong YT video I had in mind sorry, but entering the Tosa curve you should be able to identify throwing the anchor from 4th directly to 2nd I think.

I have not given the mp4/6 a proper go in AMS2 yet, but I have driven it competitively in AC. It's the only old car that I've tried so far on which it feels too fast for H Pattern shifting; it was impossible to go through all the gears on a long braking zone, and had to always skip a couple. I was on the very limit of what I could do with HnT.
 
It's also often called "gear skipping".

I tried with my former daily car, which had a manual transmission, but I also had the problem with the spacing of the pedals. As I've also owned cars with automatic transmission for the last 23 years, I have learned left foot braking IRL, as I already used it in sims. :p

I need to spend more time in AMS2 but the best clutch simulation used to be in Raceroom. I think Reiza's seriousness matches RRE's quality but I need to do some experiment. I wouldn't advice any new sim comer to learn the heel and toe technic in other sims. What do you think? I may be wrong.

Must say I haven't really though about it, myself started practicing in the real world a couple of decades before I got my first clutch-brake-gas pedal for simracing, of which GTR2 was an excellent and forgiving playground.
In more sims you can switch on forced use of clutch (if not in GUI then via car config files), in that case I'll suggest to start with forced mode = off. Though on-setting setting enforces you to learn it, but has experienced several sim newcomers experience great frustration.
Mentioning R3E I feel teased to go back racing in the DTM1992 pack. Splendid for the purpose :inlove:

Race Room won't let you jump gears in its leaderboard and online comps - it has gear change download protection enabled so that H pattern shifter users can't "cheat" with 6-2 changes and gain time over paddle shifters. It is pants. AC has, to my mind, the best use of clutch and H shifter implementation. If you have an H gate connected and the car is an H gate car, it forces you to use it and won't allow bad gear shifts. AMS 2 is as good, but you can always enable the autoclutch and get around needing to heel-toe.

I'm afraid you are wrong. I have just finished a session in RaceRoom with the Touring Classics cars in the leaderboard (BMW M3 and Nissan) and I have used the same technique as always. WIth the Nissan at the Hungaroring, I skip the 4th gear when downshifting for the turn 1 for example. It's the same in the official hotlap competitions, like in this video.

In that case my memory is playing games with me, a real pity for R3E with this content served. Maybe I was thinking of DTM- or DRM mod packs for AC.
Edit, just booted R3E up and identify my mappings were for sequential stick, which is still quite joyful together with heel&toe technique for the DTM1992s, but off-topic here.
Edit2: ok just noted post above. Now my todo list for next weekend have made me fill the remainings of empty slots in my calender :D

It´s a technique to have in your arsenal, and usefull as hell, but you have to start braking earlier, as your engine will be with the highest gear engaged while you brake, unlike when you go through all the gears.
 
The article is wrong, the proper term is : Skipping Gears and is useful either upshifting or downshifting in a vehicle equipped with a manual transmission or gearbox. The term "blocking gears" would confuse everybody in the real world.

Sure. But try going from 5th/6th to second, if you get any where near the redline on a downshift it refuses to engage the gear. And sure, you could say don't downshift so fast as to hit the redline, and I say nah ....
Downshift protection is for sequential shifters and should not have any bearing on an H pattern shifter, but RR enforces it.

You are completely right on this point; we should be able to engage the gear and over-rev the engine or lock the rear wheels (well, both! :D).

No, you don't have to brake earlier, you just have to wait longer before downshiting. If it takes 1 second to downshist from 5th gear to 4th gear when you begin your braking phase and then another second to downshift from 4th to 3rd gear, then you wait a little bit more than 2 seconds from the begining of your braking phase to downshift from 5th to 3rd gear.

Sorry for spamming this thread with my videos but I found another one which can be useful. In this lap with the Ford Mustang GT DTM 1992 @ Nürburgring GP, you can see at 2:20 with the onboard camera that I downshift from 5th to 2nd without braking earlier but I take some time before engaging the 2nd gear.

I need to spend more time in RaceRoom, going by your vids it seems that gear skip downshifts are achievable. I mainly drive historic cars and H patterns so having a good feeling with the clutch and gear shifting is vital to enjoying the driving. Missing shifts on downshifts has pretty much put me off driving RR for any length of time.

I have to admit that I get a lot of missed downshifts and also sometimes upshifts. As I only drive in hotlap mode, each thousand counts and I certainly shift too quickly too often, especially when I'm tired after too many laps on the Nordschleife... ;)

Well, if it's down to built-in rev limiter that would make sense.

In a real car you typically sense/hear when to feed in the gear and when it's far too early, causing unnecessary wear and tear on engine and gear box, as well to get familiar with perfect timing for (effective) engine braking.

But this should go for well modeled cars in sims as well anyway.

So built-in rev limiter preventing for feeding in gear should really only be modeled in cars in fact having this feature, whereas in those cars with none of this nanny aid, consequenses should be delt with as a lesson ;) (at least it's still a sim and not an unforeseen $10000 expenditure)

Last night, I conducted back-to-back races at '88 Hockenheim Short (AMS2) in the Group A E30 M3. In the first race, I drove without any heel-and-toeing on downshifts; in the second, I heeled-and-toed while downshifting, with block shifting where necessary. I was notably faster--and driving at the limit was noticably easier--when rev matching on downshifts. Anyone who wants to practice their block shifting, double-declutching, heel-and-toeing, and the like, should head on over to either Hockenheim short (or, alternatively, Nürburgring short) in the historic DTMs to learn the craft.

That doesn´t makes sense, as the engine brake power raises as you go down the gears. I skip gears downshifting a lot too, a really old video here
, specially in tight circuits, but the advantage of downshift sequentially, if you have time for it hehe, is undeniable.
