Confessions of an Automationeer, Part 7: CSR33 Results

Confessions of an Automationeer, Part 7: CSR33 Results


So far, CSR33 has been an absolute roller-coaster ride, not just for me, but for all of the 43 users who submitted a car in this round. And having explained my entry in detail, I will now recap the results of this latest round. There were a few surprises in the first round of eliminations, but on the other hand, there were also plenty of obvious choices to consider for the next round of cuts. Here, I will begin by discussing the many reasons for not making the first cut, before moving on to the subsequent stages of elimination.

When the host for CSR33 announced that this round would involve building entry-level executive cars with a touch of elegance and comfort, he really meant it. As such, cars that did not even look right overall would be immediately rejected. Considering that junior executive cars have to be larger than small C-segment cars and smaller than mid-range luxury cars, anything that was too small or large would definitely not make the cut either. Cars that primarily suffered from either or both of these aesthetic drawbacks included the Cordia Aspero, Petoskey Keeweenaw, Minerva Midnight, Evgenis Typhon, JHW Aeterna, LHE Astonish, DSD Chrome, FOA Senate and Gnoo Cityscape. One other car did not have its user name attached to its zip file, but this did not matter one bit; it was just too anonymously styled to be considered. In fact, quite a lot of cars that were submitted simply did not have the sort of styling required to make the right impression in the executive car market, with the Pragata Kana also among the worst offenders.

Even a good-looking car would be of no use if its engineering was either half-baked or excessively complicated, though, and this sadly proved to be the downfall of some of the other competitors. The Boony Continental was the worst offender: with a separate chassis, solid rear axle and anemic 1.2-liter triple, its third-world image and mechanicals was totally at odds with the target market. On the other hand, the Versal Delante, with its semi-active sway bars, was immediately disqualified for supposedly exceeding the trim engineering time limits, and would have been discarded anyway for excessive fuel consumption. And the Shromet Toldedo was just too big, heavy and old-fashioned, with insufficient power to boot. Another car, called simply the Argon, was also overweight, and in addition to being aesthetically challenged, suffered from unacceptably high fuel consumption. Surprisingly, the Beta Osmosis and BAM Bavaria 628, among a few other cars, also failed to make the cut for using semi-active sway bars and adaptive dampers (a rare combination in 1998, and one not used at all in contemporary junior executive cars), although for various reasons besides this, none of them would have won anyway

And just to ram the point home, anything with too little standard equipment would be unlikely to make the first cut. My entry, the Kramer K3 2.5, was guilty of this, but then again, so were quite a few other cars, such as the Galt Vice, Bogliq Kitten Ralleye, Hodan 445 and Valiant RZA. In short, anything that felt too downmarket to look at and/or drive would simply cut no ice with the hypothetical customer in this scenario. Could it get any more difficult for the entrants?

As it turned out, it did. Insufficient performance and/or economy was a definite reason for rejecting a particular vehicle, and once again, this led to some obvious cuts (and a few less obvious ones). The Caravel, Maesima NV-997, Scarab Nova, DMV Downdraft and Penistone Seventy-Five all failed to meet benchmarks in either category, and each one (except for the Maesima) had ridiculous company or trim names to boot. And yet, among the many failed attempts to produce a legitimate contender, there were still 10 cars that made the first cut. All that remained was to rank them, from worst to first...

The GSI Paradigm was the first of the top ten cars to be axed; its styling was decent enough in isolation, but too bland for most executives. Meanwhile, the Sei Executive, Erin Tauga, and Smooth Jabardo were all rejected for being too advanced (and hence time-consuming and difficult to engineer in real life), while the Griffa Sirion turned out to be too expensive. Next to fall were the thoroughly average Rennen Angeles and CM Regina, leaving just the podium finishers. The Iurlaro Caterina, despite not being as fast or economical as its rivals, snagged third place on account of its excellent drivability and comfort; on the other hand, the AM260, despite not having as much standard equipment, finished in second place, thanks to its combination of power and grip that its AWD system and turbocharged straight-six conferred.





The top three cars of CSR33, from top to bottom: Iurlaro Caterina, AM260 and Seishido Eccelsa

And so to the winner, the Seishido Eccelsa. The host most definitely wasn't fooled by its mediocre performance and simple front-drive chassis (strut front, semi-trailing arm rear - in fact none of the top 5 cars used a multilink rear for practicality and cost reasons), and applauded its excellent comfort and drivability, which were just what the hypothetical customer needed. Understated, elegant styling (especially in the metallic purple of the test example submitted) only sweetened the deal, especially when the chassis was tuned for all-around capability with a decent mix of sportiness and comfort. So, after one full week each for entrants to submit their vehicles and the host to review them, the biggest round in CSR history finally comes to an end.

Confessions of an Automationeer, Part 6: Defending My CSR33 Entry

Confessions of an Automationeer, Part 6: Defending My CSR33 Entry

Having sat out the previous round to allow my mind to relax after 17 consecutive rounds of participation (either as an entrant or host), I decided to regroup and prepare myself for CSR33, in which competitors were tasked with building a junior executive car for the 1998 model year. Straight away I reverted to an engineers-first mindset, but after realizing that the car would have to be engineered in 60 months and require no more than 100 production units, I was forced to make a few compromises. The question now was: what should I leave out in order to squeeze the fancier bits in?

When I found out that the design brief called for an entry-level premium car, I thought about making a premium interior, sound system, and safety suite all standard equipment, but ultimately realized that the tight engineering budget would make it impossible. So I settled on a more reliable standard interior instead. I also omitted stability control (but retained traction control) for the same reason - although back in 1998, it most certainly wasn't the universal driving aid it is now. And to compensate for the omission of premium equipment, I explicitly stated in the car's description that it was optional on the trim I would eventually submit.

The chassis and drivetrain configuration also gave me a few headaches. Originally, I wanted my CSR33 entry to be front-wheel-drive (and in fact, many of the submitted entries were), but quickly changed my mind after deciding that I would rather emphasize sportiness, and switched to rear-wheel-drive. Also, the suspension started out as struts up front with a torsion-beam rear, but the latter was replaced with semi-trailing arms, and eventually I opted for control arms at both the front and rear. However, I discovered that I still had some engineering time to spare, and used some of it to install a multilink rear instead, thus improving drivability, sportiness and comfort even further with minimal loss of reliability.


Originally intended to be a front-driver with a transversely mounted engine, a strut-sprung front and torsion-beam rear, the Kramer K3 2.5 emerged as a rear-driver with a longitudinally mounted engine, double wishbones up front and a multi-link rear - and all the better for it.

Designing an engine for the car was no cakewalk either. With the maximum engineering time and production units for an eligible engine capped at 80 each, I was forced to rule out any configuration with more than six cylinders in it, and settled on a straight-six with dual overhead cams, variable valve timing and lift, low-friction pistons, and 2550 cc of displacement. I did, however, ask myself one question: Would a straight-four have been as effective? The answer turned out to be a definite no: the loss of sportiness and prestige clearly outweighed the increase in economy it would have provided. Moreover, I used a normally-aspirated engine, since a turbocharged one would have put me well over budget in terms of engineering time, and even if it didn't, I would sacrifice too much drivability in the process. I was quite happy with how it turned out, though.

As for the remaining trim components, I made choices that would prioritize sportiness over comfort, but kept the use of quality points to a minimum, although negative quality was out of the question. Specifically, the manual transmission made the car harder to drive and reduced the comfort rating, but provided a significant boost to sportiness, while the fitment of all-season tires were ideal for this car's role as a daily driver - high-performance tires would have been at odds with the design ethos if I had offered them as standard, even though it would have increased the sportiness rating even more. In addition, I opted for a combination of a viscous limited-slip differential and vented disc brakes (two-piston calipers up front and single-piston calipers at the rear, plus an anti-lock braking system), providing a well-rounded balance between drivability, sportiness, affordability (both in terms of engineering time and estimated price) and comfort. Finally, I tuned the suspension (which incorporated progressive springs, passive anti-roll bars and monotube dampers) to provide a sporty feel while retaining the drivability and comfort levels expected of a daily driver.






In setting up the K3's mechanicals, I optimized its sportiness while also retaining a decent amount of comfort and drivability.

With the mechanicals and trim now definitively sorted, I was left to finalize the exterior design. However, considering that the car's looks had to convey the right image, the shape, quantity and placement of the fixtures was crucial. After all, entry-level executive cars ought to exude a form of restrained elegance without being too bland or, on the other hand, excessively ostentatious. As such, I decided to keep it simple on the outside, and jazz up some of the fixtures with some chrome trim.

Moreover, the car's exterior color also had to befit its image, and I went with a dark, lustrous red which I called Deep Claret Metallic - I could have chosen a deep blue or green instead for a similar effect, but I stuck with red anyway because I  believed it felt more upscale than the other two. I also found black to be too intimidating, silver or gray to be too dull, and white to be too flashy. And I deliberately extended the rear end as much as the body will allow me to in order to increase the amount of cargo space available, and raked back the A- and C-pillars quite a fair bit to give a sportier side profile.



The Kramer K3 2.5 is known for its stylish exterior... and a huge trunk.

Only time will tell if my enthusiast-focused approach delivers a satisfactory result, but I am certainly going to take pride in what I have built and submitted for this round. For one, making compromises when there is a maximum limit on production units and/or engineering time for the car and/or its engine is not easy, and success here often boils down to using the right equipment. In the lite campaign, where profitability hinges on releasing your cars soon enough to boost sales, this is even more important. As for the results of the current round... well, that will have to wait until the next post.

Confessions of an Automationeer, Part 5: A Retrospective on CSR32

Confessions of an Automationeer, Part 5: A Retrospective on CSR32

As the latest installment of the longest-running Automation community challenge comes to an end, I will share my thoughts and opinions on the requirements, entrants and results on this post, especially since I started writing it on February 1st, which is the deadline for submissions for CSR32. Some of you may be wondering why I am discussing a round which I did not host but did not enter. Well, as it turns out, it perfectly summarizes the problems faced by customers in my home country when they want to buy an entry-level car. The fact that regulations here are particularly lax when compared to those found in developed markets (such as Australia, Europe and America) does not help matters either. Unsurprisingly, after the farcical conclusion to the previous round, I was hoping for the host to implement a totally different rule set from what he eventually came up with - but I could not have been more wrong.

When I first saw the rule set for CSR32, it hit me closer to home than ever before. Although the 28th round also required entrants to build cars suitable for the Indonesian market, that round's rule set classified entrants into sporty station wagons, dedicated sports cars and crossover SUVs. Without going into too much detail, the requirements for each type of car were challenging, but not too strict. The current round, on the other hand, turned out to be much tougher.

Even though I didn't feel like entering the current round, I decided to take a look at the rules anyway. Almost immediately, I was taken aback by how strict and demanding they were: not only were the cars required to be 5-door hatchbacks with at least 4 seats and cost no more than $11,000 with a 20% markup, but they had to be extremely economical (47 US mpg/56 UK mpg, or 5 L/100km) and have an engine of no more than 1200cc (1.2 liters). On top of that, minimal running costs, a modicum of safety, and the ability to use regular unleaded fuel were all mandatory, but the worst part was the $500 penalty for each driving aid included as standard! Understandably, I threw up my hands at this convoluted rule set the moment I saw it, and left the task of building and submitting eligible entries to other users.

However, within just one week, most of the reviews had been posted, and I soon developed mixed feelings about taking a break from CSR. While I now considered it one of the toughest rounds in the history of this challenge, I somehow regretted not taking the opportunity to step out of my comfort zone with a competitive ultra-low budget build, especially since there were plenty of strong contenders for outright honors in this round. On the other hand, there were also quite a few cars that clearly would not have made the first cut due to one or more poor design and/or engineering choices. And after some deliberation, the host awarded the overall win to... an SUV. Specifically, it was a crossover, but although it wasn't a compact passenger car per se, it was still cheap, economical and practical (it had seven seats, after all) - just as the design brief stated. That said, the second-placed car would have been a good choice for those who would rather prefer to focus on economy and running costs - a philosophy that the third-placed car took to greater extremes at the expense of even less practicality.

Thus ends one of the most challenging, yet rewarding rounds in CSR history. And as I now settle down to prepare for the next round, I will prepare for the upcoming CSR33 - assuming it is worth the effort. At the same time, though, I can't help wondering how different a cash-strapped Indonesian car buyer's situation would be if both of the top two cars in CSR32 existed in real life. In that case, he or she would enjoy a stunning blend of practicality and economy, without having to make too many compromises in the name of affordability. And isn't that exactly what the market really needs? I sincerely hope it is.
