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.

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.
And in real world may I suggest trying this in e.g. a caged lightweight Suzuki Swift Sport with classic H-pattern on Nordschleife.
To this date still my far best and most enjoyable Nordschleife real world experience; a car with less power than grip, but still OK power/weight ratio, small wheel base, classic use of clutch heel&toe and then (for me the new term though been using it for +30 years) "block shifting" to throw the anchor for the tighter corners.
Personally I felt more thrill and joy than far faster Porsches with paddleshifts.
Almost equalled my thrill trying some 80ies Reynard FF2000 single seaters at tight corner tracks.

The biggest issue is that most H-pattern gearboxes in racing are dogboxes, W
Without synchros. You only need to lift the throttle for upshifts or downshifts. Downshifts in such a gearbox when not using the clutch are quite easy though unpleasant. And I speak from experience, as I have a dogbox in my Time Attack car. Yet in most sims it's as if all race cars have regular manual gearboxes which force you to fully press the clutch when changing gear. And if you don't do this, a gear won't be engaged. Dirt Rally 2.0 is especially terrible in this regard.
Check out the VRC TA2 cars, they have simulated dogboxs. Clutch only needed for start. Then a lift on up shift and a throttle blip on the downs. But you are correct most cars in the sim world are not like this.

Yeah, the term "block shifting" is simply a synonym for what I usually call "skipping a gear". Call it what you like; a driver should be comfortable with (a) downshifting sequentially through each gear on the way down, (b) skipping past one or more gears to downshift to a midpoint gear before selecting the final gear (e.g., going from 6th-to 4th-to 2nd) and even (c) skipping past one or more gears to downshift directly into the desired gear, if indicated ... which technique works best for a particular corner and/or vehicle will quickly become apparent.

Block shifting is not an English expression. It'd be jumping gears or skipping gears when referring to the practice of missing out gears in sequence when downshifting. Whatever it's called, that video of Schumacher going from 6th to 2nd and redlining the #### out of the Benetton into T 1 Monza in the first post is magic.

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:
The DTM92 pack, that's a good idea!!! I haven't been using it for (too much) years. GTL is also a great sim to practice the technique. Unfortunately the FFB doesn't work properly on GTL, GTR2 and P&G. I need to find a solution, with Race07 FFB settings. I just made some practice laps and launch a multiplayer race in AMS2 with the Group C Corvette, this car is absolutely amazing. AMS2 properly simulate the clutch, with such a raw car, H&T is the way to go. Next session will be the DTM92 pack in Raceroom...
 
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.
Wow, I usually skip only one gear, except with Formula 1s, so I've never noticed that in Raceroom. That's not good. AC's clutch implementation is not good, there are an automatic start and an automatic clutch at first gear which prevent ypu from stalling. It seems only AMS2 fully simulates the clutch and the H gear shifting. Well, with AMS1 and the old simbin sims (I've tried the classic cars of Race07 today, I had never used them, they feel great and are very fun to drive! And good to practice the "pedals dance").

Not sure about vanilla AC, but Content Manager certainly permits disabling of autoclutch.

The Mclaren MP4/5 and Mp4/6 in AMS2 are the absolute limit of H pattern shifting in sims. These two represent the point at which the engine revs of the V10s and V12s were getting too fast for a H shifter to keep up with. having said that, the MP4/5 around somewhere like Jacarepagua is just a never ending white knuckle ride. it is such a workout and so tiring, you can understand why they all switched to paddle shifting in the following years.
 
If a car's braking distance is relatively short (like a 90's F1), skipping multiple gears works great but if braking distances are long like in an 80's Group C - on a long straight into a 2nd gear corner for example, I downshift from flat out 5th to 4th to provide immediate engine compression, then hard on brake to get the rpm down and then 4th to 2nd. Seems to get me decent lap times, saves the brakes a bit, and avoids a rear axle lock spin out.

I haven't checked whether AMS2 simulates gearbox breaking, as Raceroom does. Someone managed to break it?

I just did laps with several manual gearbox cars and there is no gear protection. You must have some aid activated somewhere. I had forgotten but I've always got gearbox damage when downshifting too early in Raceroom (bad gearbox sound and orange color on the transmission indicator). I could reproduce this today, downshifting too early, skipping several gears, and I was able to lose control by doing so (and to hear the gearbox damage sound). There are not so many cars with 6 gears in Raceroom, I just found the KTM Xbow. Group C, Group 5, DTM92, these cars have 5 gears. I wonder in which cars you found this issue.

By the way DTM 92 pack is amazing, these cars are real beasts and not easy to drive at all.

Racing online in the comps is different than offline in these cars. What is gear damage/grinding offline will more likely appear as a mis-shift and a neutral in the online comps. I remember in the forums ppl saying the downshift protection was enabled in the competitions for the H gates too as a way of preventing an unfair advantage through abusive downshifts, so I've always put it down to this. I tried RR today for the first time in ages, in the Group 5 monsters and the gears failing to engage on downshift is the same, you absolutely cannot engage a lower gear if you are going to send the revs into the redline on the downshift. You have to wait on the roadspeed and rev range to be in sync, and then you can jump gears or just go down through the box.
 
It disables the autoclutch but there is still the autostarter kicking after a stall just by accelerating and without going through neutral.
Interesting. As per spinal reflex I always go through neutral under those circumstances.
Think I'll pretend I've never read this fact and just continue my immersions :p

Well, as I said, you must have some aid activated because I could do it. Or is it possible to use the H pattern with sequential cars with the gearshift protection? It would make sense to keep that protection on.

Yes, me too, reflex (better to keep it), and with a bit of experience these (really bad) circumstances occur less often than before :D .

I never use aids in any sim. The point is, if you change from say, 5th to 3rd too fast the game will not allow the change. The point of jumping gears is to make it a one-change downshift instead of having to do four. RR won't allow redline down changes. I have to rewire my racing brain to drive RR, slowing my roll the every time I'm in a hard braking zone and wanting to do just 1 or maybe 2 shifts. Maybe that's a good thing, I'll need to spend more time in the M1 to find out.

The BMW M3 Sport Evolution DTM 1992 (and maybe the Mercedes 190E Evo II DTM 1992, I am not sure) uses a 6-speed gearbox.
