Proposed 2022 Regulation Changes

This has been sent as an email to all 2021 registered competitors. Please leave your comments here for all to see.

We are proposing the following changes in the championship regulations for 2022. All changes are guided by the following principles:

 

  • Remove unnecessary restrictions and simplify the rules to encourage participation with all different types of Caterham and Lotus 7.
  • Make the rules as fair as possible to encourage competition.
  • Encourage newcomers to the sport.

 

We have tried to follow these principles in formulating these changes.

 

Technical

 

Class 1. Simplify the engine regulations as we have already successfully done in classes 2 and 3 with a simple power limit.

 

This class is for Lotus or Caterham Seven, road cars – specialist production and has a maximum power limit of 130bhp.

They shall be powered by:

  1. Any normally aspirated car derived engine up to 1600 cc
  2. The 3 cylinder turbocharged 660cc engine as fitted to the Caterham 160, 165 and 170 models.

 

Class 2 and 3.

 

Further simplify the engine regulations by removing the higher power limit for single cam engines.

 

Remove

“Single cam engines of 1601cc and greater. Power for these engines is limited to 160bhp”

 

Class 4 and 5

 

We now find ourselves in a tricky situation with class 4. The lack of supply of the preferred list 1C tyres means that just about everybody with engines producing more that 155bhp will end up in class 4. We propose putting a power limit of 220bhp (no tolerance) on class 4 and making class 5 an equivalent class for cars with more than 220bhp.

 

The most difficult part of this is what to use as a basis for records of the new class 5 needed for overall championship calculations. We have looked at the times achieved by the 3 drivers competing in class 4 in 2021 who previously competed in class 5. Comparing these shows an average time loss of 2% between 1B and 1C tyres. We propose therefore to add 2% to class 6 records and use these as notional records in the new class 5. We will review this before  2023. For Veterans, Novice and Ladies Championship calculations we will use the winners time on the day.

 

Class 4:

Any Lotus or Caterham Seven, road cars – specialist production and has a maximum power limit of 220bhp.

All cars must be fitted with an operational reverse gear.

Tyres to be any road legal E-marked radial tyre or listed in the current Motorsport UK General Regulations Permitted Tyres (L) Lists 1A and 1B .

Cars powered by non-car derived engines or equipped with sequential gearboxes are not allowed in this class.

 

Driver Aids are not permitted in this class.

 

Class 5:

Any Lotus or Caterham Seven, road cars – specialist production not meeting the engine requirements of Class 4 including those with forced induction.

All cars must be fitted with an operational reverse gear.

Tyres to be any road legal E-marked radial tyre or listed in the current Motorsport UK General Regulations Permitted Tyres (L) Lists 1A and 1B .

 

All Driver Aids are permitted in this class.

 

Classes 6 and 7 to remain unchanged, although we are not expecting any entries in Class 6.

 

 

Nominated events for overall championship scoring.

Add Aintree and  Blyton Outer

 

Dual Drives:

 

The driver who finished higher in the previous year’s championship will run first or in the previous batch wherever possible.

This is to reduce  any possible advantage for the faster driver by running on warm tyres.

 

Eligibilty for scoring championship points.

 

Only drivers entered in the Caterham and Lotus Seven Club Classes will be eligible to score points.

This is to reduce the likelihood of competitors competing in different conditions

 

 

 

 

Scoring for novices, veterans and ladies.

 

Based on whichever is the faster time of the existing class record or the class winning time in the day. 

This avoids situation at 3 Sisters this year where existing records were set in wet conditions.

 

 

 

 

Curborough Events

 

We have the option to have only one practice run meaning that the second run will be a timed run. We would like your opinion and will probably have an online vote. This can be decided after publication of our regulations.

Thanks for the hard work that had obviously gone into this Graham / team.  Can I get the ball rolling with a few suggestions?

Class 1 "The 3 cylinder turbocharged 660cc engine as fitted to the Caterham 160, 165 and 170 models."

I suggest changing this to "A 3 cylinder... " since the engine used in the 160/165 and the 170 are different.

 Remove “Single cam engines of 1601cc and greater. Power for these engines is limited to 160bhp”

There is no doubt that single cam engines are today in a tiny minority, but as I understand it, this exemption was very specifically put in to create a more level playing field between the power delivery characteristics of older single cam engines against more modern twin cam engines.  I’m not aware of it ever having caused an issue so why remove a provision that supports the aim of making the rules “as fair as possible to encourage competition” as per the preamble? (for the avoidance of any doubt, this is not currently of any benefit / advantage to me personally).

Driver Aids

We talk about classes where these are and aren’t allowed, but do not seem define what we mean by them, which I suspect might be confusing for anyone outside of the competition.  Worth clarifying?

Club name

Will need to be updated throughout  Byebye

Thanks Michael for your comments.

We are guilty of not studying the specification of the Caterham 170 thoroughly enough! We will do as you suggest.

Removing the increased power limit for single cam engines is all about simplifying the rules and it is highly unlikely that anybody now will take advantage of this, so it seems redundant. What are the chances of anybody wanting to compete with a 160 bhp cross flow? We took out a similar dispensation for Lotus twin cam and Cosworth BD series engines last year and nobody noticed. 
 

Perhaps "Mr Driver Aids" Simon Rogers would like to comment on the subject of driver aids. The 2 that come to mind are traction control and any kind of sequential or automatic gear change.

And yes it is a given that the Club Name will be updated throughout the regulations.

Further excellent work in solving the conundrum of many different specs offered by Caterham over the years, popular modifications to those cars all distilled into 6 or 7 easy to comprehend classes

Whilst it clearly does not directly affect me my only question is the choice of 220BHP for the class break. As 210 would cover the current 420 model and many of the R400 type models from the past is there a particular reason for this. I know it is only 10bhp but you know how competitive we all get so if there is not a good reason it just seems to open the door to competitors feeling obliged to upgrade to be competitive

Yes, I think these are appropriate changes to simplify and clarify the championship regulations. 

However, there is a line in section 3.3 the 2021 regulations that reads:- 

Cars in any class may use engine modifications that improve engine reliability and longevity, e.g. forged pistons, uprated valve springs, gaskets and bearings, providing no performance gain is achieved.

As all other modifications are free, that line seems to be redundant. 

On the subject of "driver aids", I suggest specifying "traction control", "Launch control", and "flat shift" (to cover either manual change with shift cut or and integrated paddle shift system), as specific "driver aids"

I think we need to be careful in the new class 5 of excluding one or two cars.

The 620 comes with Launch control as standard I think????

There are also quite a few 620's being upgraded to paddle shift.  They already have a sequential and with the lack of suitable tyres for Class 6 and FHR etc I think Class 5 should be open to driver aids of any description.

Class 5 should be our catch all anything goes Road Going. List 1B  We always had a catch all anything goes class and believe we should retain it.

Absolutely Class 4 can exclude them.  
 

I don't think Semi Active provides a performance gain in sprint and hill climb.  Yes I am selling them to lots of road guys and again I would just not want to prevent one of those cars joining the fun.  If I thought there was a gain aI would be using it!

Back to the as few rules as possible stance for me.

 

Richards comment above is perfectly sensible.

"Autopilot"?

220 is selected as its 210 "plus a bit" in case a factory 210 on the rollers comes out slightly above 210.

We previously had 150 "plus a bit"  in class 2/3, and found it better to say 155 full stop.

I agree with Simon ( yes, I know that's unusual Wink ). I don't think electrically adjustable suspension will offer any performance advantage for speed events. If it did, we would have seen all the top cars in the British hillclimb championship using it! (which they are not!)

Dual Drives:

 

The driver who finished higher in the previous year’s championship will run first or in the previous batch wherever possible.

This is to reduce  any possible advantage for the faster driver by running on warm tyres.

The problem then is that the faster driver is then running out of class which could result in an advantage/disadvantage depending on weather changes so in direct conflict with the suggested rule for drivers competing in other championships. In the past we have agreed that the warm tyres benefit is minimal due to the normal gap between batches.
