Audi R15: The Forgotten Audi LMP

Hi everyone.

This blog post is about what I consider the forgotten Audi Le Mans car.  It tends to get overlooked because it wasn't as successful or long lived as other Audi LMPs.  However, it set two distance/speed records that will probably not be broken for a long time, and set the tone for its more successful successors.

The Audi R15 was created as the successor to the R10 and to provide a continued answer to the Peugeot 908.  While the R10 had the 908 beaten on speed and reliability at their first meeting at Le Mans in 2007, the newer 908 had more development potential, which showed in early 2008.  Audi won Le Mans thanks to better tactics, reliability and adaptability, and they closed the gap in performance during the season.  But the R10 was a relative dead end as far as development.

The R15 was hoped to be more agile and easier to drive than either the R10 or 908.  And though the car showed potential in testing, between rain and accidents in testing, the R15's test regimen wasn't as successful as hoped, and ended up showing up to Le Mans with teething problems that didn't even show up at the car's successful debut at the 2009 12 Hours of Sebring.  In so winning at Sebring, the R15 set the all time distance record for a victor at the Sebring 12 Hours, a record that still stands and will likely stand for a while yet.

Le Mans, though, was a relative disaster by Audi Sport standards.  One car finished well back due to mechanical problems, one crashed out, and the other finished 3rd after battling overheating issues and a lack of top speed during the event.  

Hence, it can be argued that the R15 didn't live up to its hopes.  The R10 struggled with top speed vs the 908 in 2008 at most circuits.  This didn't hurt the R10 much as it won at tracks like Silverstone and Road Atlanta for the Petit Le Mans, where its handling advantage over the 908 worked in its favor.  But at Le Mans, with 5 zones were the fastest cars can easily hit speeds of over 200mph, the speed deficit showed.  Only by being better in rainy conditions, better strategy and tactics, and better durability did Audi conquer Peugeot at Le Mans in 2008.

At Petit Le Mans at Road America--a track that suited the early incarnation of the R15 just as well as the R10--Audi dominated in both wet and dry conditions, only for late race spins to cost them a likely win when the race was stopped due to a flooded track.

Keeping in mind the Le Mans performance deficit to Peugeot and other minor problems that held them back, Audi Sport redeveloped the R15 for 2010, keeping only the chassis, basic suspension, and the 5.5 liter V10 TDI engine and 5 speed gearbox.  Every body panel on the car was otherwise changed.  

That re-engineering did close the gap to Peugeot, but not completely, at Le Mans.  However, the pace was hard and record setting during the race.  And the effects showed with the Peugeots suffering terminal problems, leaving the slightly slower, but more consistent, and more durable Audi R15s to take a 1-2-3 finish at Le Mans.  And like at Sebring a year in a half earlier, set an all-time distance and average speed record that's unlikely to fall anytime soon.

Performance against Peugeot was on par for the rest of the Audi vs Peugeot encounters, though further victories eluded Audi until the R18--which was developed based on feedback and developments from the R15--entered use.  And thus, started a new generation of Audi Le Mans Prototype cars that featured smaller engines, enclosed cockpits, and, ultimately, hybrid systems.

Audi R8: Where the Name for the Audi Supercar Originated

 

Hi everyone.

 

I've written a lot about the Audi R10 lately, but what came before it? One of the few Audi Le Mans cars that was more successful than it was. So successful in fact that Audi named their flagship supercar after it. The Audi R8. 

 

From 2000-2006, it won 80% of the races it entered, and influenced several features on the R10 and other cars that came in the R8's wake. We kind of owe modern Prototype road racing to it in many ways. 

 

It incorporated several F1 like technologies, including a roll over bar that withstood 3x what was required of it. It also spawned a successful customer racing program that took over when the factory team left to concentrate on the Audi Sport supported Bentley Le Mans Program for 2003 (which also used the R8's engine and electronics) and what ultimately became the R10. And it also spawned modular design, something that was taken further by the R10 and others that followed. This included a whole rear end assembly that could be changed in less than 5 minutes. 

 

Also of note for road cars, the R8 introduced to racing direct fuel injection for gasoline engines, inspired by then modern diesel technology. Now DFI is very widely used on road cars by many manufacturers, as it boosts both fuel economy and performance.

 

As the car raced in multiple year and some are even still encountered in vintage/historic racing, I decided that for the sake of brevity that I'd post the page to links on info and specs on all versions of the R8:

Audi R10: Introduction into Modern Era Diesel-powered Auto Racing

 

Hi everyone.

 

This post is a change of pace--literally. Instead of talking about World War II or the technology from that period used in that conflict, I'm switching genres and time period. While my electricity was out after the Sunday windstorm, I started to get back into auto racing and the history of it. I won't be reaching back too far, in this case 2006-2008 with one of my favorite racing cars of all time, the Audi R10.

 

It was notable for being the first diesel powered car to win Le Mans, one of the first to have notable success in auto racing, period, and its design and construction influences top class Le Mans type racing cars nearly 15 years after it broke cover.

 

Even though diesel powered cars no longer race at Le Mans (that ended when Audi Sport withdrew from top flight prototype sports car racing in late 2016), the basic design of the R10 is still a design influence. Even though it's open cockpit (which became less common after 2008 and eventually totally phased out at Le Mans in 2017), it's chassis design is still pointing the direction to go. Almost all Le Mans Prototype cars still use a "all monocoque" chassis, where there's no bodywork covering the chassis beyond non-structural elements. This allows the whole front and rear clips of the car to be detached in big chunks for rapid changes of damaged parts, set up changes and chassis/suspension adjustments.

 

Then there's it's 5.5 liter V12 turbodiesel engine. Both the engine's basic design principals and being a diesel were outgrowths of the earlier R8 program (the current Audi super car and GT racers were named after the earlier R8 LMP car). Namely, the R8's (and Audi road car) direct gasoline injection system was an outgrowth of Audi's TDI (Turbocharged Direct diesel Injection) system, but applies to gasoline engines. With the R10, things came full circle.

The engine made over 650-700 horsepower and over 900 lbs/ft of torque. In a car that weighed 900-925 kg (depending on series rules and season the car competed in), and, initially, had no traction control (and even then barely worked most of the time, which the drivers actually appreciated it's minimal interference). When the R8 raced, traction control was illegal and only became legal in 2006 (though the R10 initially ran without it).

 

The car didn't just impress with its speed, but relative near silence on account of the turbocharged, low-revving diesel engine. When on considered that the earlier R8 (which used a 3.6 liter turbocharged V8) wasn't especially loud for a race car, that's saying a lot.

It also helped introduce the modern long wheelbase design into LMP racing. This was partly to keep as much weight as possible within the car's wheelbase for handling reasons. It also enhanced handling at high speeds and in rapid direction changes. It also allowed the R10 to run to near the maximum LMP1 car length of 4650mm, given that LMP1 cars from 2006 to 2020 were restricted in terms of front and rear overhang (distance of bodywork allowed to extend beyond the confines of the wheelbase), though wheelbase (distance between front and rear wheel centerlines) was unrestricted. Formula 1 cars and Indy Cars, for example, also run such long wheelbases for the same reasons.

 

For reference, Audi Sport compared the R10's wheelbase to that of the then similarly new first generation Audi Q7 full size SUV, and is still comparable to full size sedans and full size SUVs. This, however, posed no impediment to agility for reasons mentioned above.

The only Audi prototype that was more dominant or accomplished in racing was the earlier R8, who's DNA was all over the R10. From here on out in this post are links to info, photos and videos.

Now I'm a PC Gamer

 Hi Everyone.

My younger brother recently got a PC tower, primarily for gaming, recently.  We've had it for over a week now.  And I've enjoyed gaming on it more than I thought I would.

So far, I only really have one game that I frequently play on it. And that's the PC version of Hitman 2: Silent Assassin.  I've talked about that game before, but the PC version in a few ways is a different animal, pretty much for the better.

First, instead of some strange auto aim where when two things are near your aiming reticule, and bullets tend to go to the nearest of the two, now you can actually shoot at what you're aiming at.  Hence, you don't have to pussyfoot around and hope and pray your aim does what you want it to do.  

Also, the graphics are a huge improvement over the PS2 version.Colors are brighter, graphics are smoother, and I'm getting 60fps out of it all the time.  Even the controls are better.  I know that some may or may not like WASD for movement, but I like it.  Biggest improvement there is mouse aiming.  It makes movement, not just aiming, but simple looking around or simple direction changes a lot more responsive and easier and more flowing.  

 As for the future, I'm looking into getting an emulator system for it for most of my PS1 and PS2 games, and looking at getting some of the Call of Duty games for it from back in the day.

I'm thinking that I'm going to really love gaming on the new PC. I'm also looking at getting a new laptop, not for gaming, but for basic looking up stuff online and viewing photos.  I'm open for suggestions.  I don't need much storage (I already have an external hard drive and thumb drives), and I'm looking for 14 to 15.6 inch screen and a $250 or less price tag.  

Other than that, I haven't been up to much.  I did get a new pair of glasses that I love wearing.  I'm probably, since it's getting colder and such, going to be watching more TV in the living room.  Also on Tuesday, I have a Halloween party with Best Buddies.  I'm really looking forward to that coming up.

 Also, I'm hoping soon to be doing some reorganizing in my bedroom.  Mostly getting rid of something on my desk that's storing a lot of stuff and have the PC tower up there on the desk, and some more room for lighting and such, too.

 Everyone have a good one :)

A Little Bit About Myself

 Hi Everyone.

I decided to make a bit of a post about myself where instead of talking about technical stuff or history and such, I want to talk a bit about me.

 I'll just be rattling off some stuff about me that some of you may or may not know about me.  But it's stuff that I think some of you might find interesting.

First of all, I do like to cook.  I love making slow cooker stuff, as well as home made fried chicken.  Even stuff like boxed pasta and French fries is stuff that I'm always interested in making.  In fact, earlier, I made some seasoned fries where I baked them for a while, then finished them in a deep fryer.  You can also use an air fryer for the frying part. I really love cooking and mixing up drinks as far as drink mixes.  And tacos, calzone-like creations, stuff like that.  

And a lot of you probably know that I'm into history and such.  Be it World War II, cars, motorsport, weather.  I love researching the past.  It also leads to IMO kinda weird stuff like thinking "how would this have done back in World War II) and such.  I also like looking into obscure junk and stuff that was flawed.  That's always had a bit of charm for me.  

Also, I'm into women's fashion and things related to that.  I'm big time into doing women's nails.  That's been something that I've been into since I was little.  I haven't done that much in recent times, but I did a friend's recently and she said I did a pretty good job.  It's just something that I find fun and interesting to do.

 Also in recent times, I've been becoming more social.  I've been trying to talk to friends online and when possible hang out with them.  I'm trying to see what I can do next and when.  That's much better IMO than how I used to be, which was kinda anti-social and even scared of other people in general.  I haven't always had a positive image of humanity, but I'm trying to change that.

 I know that this will probably be a bit of a short post, but I hope that you'll still enjoy reading it.

Have yourself a good one :)

Hangin' with Friends and Some Gaming Stuff

 Hi everyone.

The first thing that I'd like to say is that I've had so much fun hanging with and talking to my friends Victoria and Colton recently.  I haven't been able to show them the Bird Sanctuary yet, but it's on our list of things to do before winter.  Also, some sight seeing around Columbus is also something we're looking into.  

I'm also hoping to get some info soon on Best Buddies.  Victoria and one of our other friends Sara is working on that with some others.  Hopefully in a few days there'll be something concrete.

As for gaming, I'm about to move on to Gran Turismo 4 after literally nearly a year away, but first I'm trying to finish up a few things on Hitman 2: Silent Assassin.  I do have a few things to note about the game, though.  

One, is the AI in the game--or, maybe, lack there of.  It's something that certainly incentivizes stealth for sure.  However, I don't play it stealthfully, and the idiot AI is a mixed blessing.  The AI sometimes will behave as if they have no sense of self-preservation, or maybe they have a death wish.  

What I mean by that, is that the unarmed NPCs will run or walk (or stand or crouch) between you and an armed enemy NPC (usually a target's bodyguards or enforcers), which is an invitation to get shot by someone.  If you're trying to lay waste to a map, that's OK.  But when you're only trying to take down the armed NPCs, it can be very frustrating.  It also results at times in the armed NPCs accidentally shooting and killing the innocent NPCs.  Which means that I can "retaliate" against them for their act of manslaughter.  It is however sometimes comical seeing the armed NPCs have to pussyfoot around the idiot AI like you have to, though.

Maybe now's a time to bring up you can't spell "assassin" without using a certain word twice...?

And now, a word on the arms of Silent Assassin.  One is a rather mundane pistol that has a legendary (but somewhat erroneous) reputation, and the other is a weapon that's not at all common as it is in the game.

First of all, the PSM pistol (identified as the 5.45mm Pistol) in the game.  It only appears twice, and both times in the hands of Russian operatives, one being a FSB agent (accurate) and a Spetsnaz officer (less accurate).  In the case of the FSB, the PSM is fairly commonly in use in Russian (and some other former Soviet countries') law enforcement, as it's popular with plain clothes police officers and detectives.  And it is sometimes used by the Spetsnaz, basically Russian Armed Forces/Soviet Armed Forces spec ops.  

This, of course gave rise to it being alleged to be a popular assassin's weapon, due to it's small size and alleged formidable capabilities against certain types of light cover, and light body armor (such as flak jackets and bulletproof vests).  The latter is mostly true because of it using jacketed ball (aka hardball) bullets instead of unjacketed lead bullets of similar caliber (5.45mm is roughly .22 caliber).  That said, it's not an impressive round.

Ballistically, it's actually fairly similar or slightly more powerful than .22 Long Rifle.  However, that suits the PSM's actual purpose.  It was originally designed for Soviet Army and Air Force generals and Soviet Navy admirals as a compact pistol to be hidden in a special holster under their uniform blazers.  Basically it is to the 9x18mm Makarov PM pistol as the .32 and .380 Colt M1903 pocket pistols were to the Colt M1911 .45 pistol back in the day for the US Army. Smaller caliber weapon was issued to generals not expected to see serious combat.  Larger caliber pistol was issued to officers, NCOs and rank and file troops expected to see serious combat.  

In terms of the initialism, PSM is an abbreviation of the Russian phrase meaning "small self-loading/semiautomatic pistol".

But the PSM does have a legend to it, though one mostly perpetulated by films and video games rather than real life.

Also in Silent Assassin, in the Afghanistan levels, the Russian AKSU-74 compact carbine (or submachine gun as the Russians tended to term it until about 15 or so years ago) is insanely common.  Again, this runs counter to real life.  

It's inclusion was probably inspired by films and video games like Goldeneye where the AKSU featured prominently.  Let alone the fact that infamous terrorist Osama Bin Laden frequently was pictured with one in photos and videos.  The latter goes along with the US/NATO invasion of Afghanistan following the 9/11 Terrorist Attacks (the Hitman game franchise was developed by IO Interactive, a Danish software/gaming company.  And Denmark was a founding member of NATO and has been active in Afghanistan against the Taliban and Al-Qaeda).

However, the AKSU-74 (AK stands for Avtomat Kalashnikova, literally Kalashnikov Automatic Rifle, S for folding stock, and U for shortened, 74 for 1974 model year) is a relatively rare weapon in real life, and in fact is being phased out of the Russian Armed Forces in favor of a more advanced replacement.

Also, most AKSUs weren't made by Izhmash (now Kalashnikov Group), the majority being made at the Tula Arsenal from 1979 to 1993, when mass production ended.  Which means that among AK-47 based weapons, the AKSU is a literal drop in the ocean, and hasn't even really been produced since the likes of Victoria Justice, Ariana Grande and Liz Gillies were babies.  

It also wasn't particularly popular with the Soviet/Russian Army.  Only the Spetsnaz seemed to like it.  Between that and being out of production for over 25 years, it's being replaced by the AM-17, a Kalashnikov Group modernization of the rediscovered Dragunov MA.  The latter was designed by Yevgeny Dragunov, a gunsmith better known for the SVD sniper rifle.  It was originally a test bed for polymer materials being used in rifles by the Russians back in the 1970s.

So that's it for Silent Assassin.  I'm planning on buying a "new" PS2 off Amazon soon and a 256GB memory stick on Tuesday, and I'm looking into getting a 14 inch laptop whenever I can get the money.  

And of course, I'm looking forward to more adventures with Victoria, Colton, and others, too.

Eating and Gaming

 Hi everyone.

This is going to be a fairly mundane blog post about a couple of things I've been up to.  Mostly what I've been eating for dinner lately and some gaming stuff.

Basically, I've become addicted to pasta and slow cooker beef and onion dishes.  I've been eating a ton of Pasta Roni boxed pasta meals.  Basically, I've had just about everyone of them that was inspired by traditional Italian pasta dishes.  Namely butter and herb, Parmesan cheese, fettuccine Alfredo, broccoli and chicken, and chicken fettuccine.  All of which are pretty good, and all of which are pretty cheap.  Almost every place that sells them retails them for about a dollar.

I've also taken a liking to slow cooker beef and vegetables.  Be it pot roast or my upcoming attempt at beef and French onion soup.  I have onions, will be getting beef broth and steaks, so why not?

And for desert, well, I usually eat cereal like Crispex or Chex, or ice cream.  Meijer has Hudsonville brand ice cream, while Walmart has started to carry Turkey Hill (which Kroger already was).

Now to shift to gaming.  So far, as far as actual games, it's been the same old, same old.  Mostly Hitman 2: Silent Assassin.  However, I'll be doing some racing games soon since Le Mans is coming up next month.  However, I bought a Pound HDMI adapter for my PS2.  And it's a huge improvement over AV composite (or whatever the Yellow/Red/White wires are), or the RCA to HDMI adapted I used previously.  Text especially is do much sharper and easier to read, and color and such is pretty good as well.

Previously, I felt I was taking an eye exam with how blurry some images were.  Granted, my eyesight isn't the greatest to begin with.  But now at least I can read text in my PS2 games without excessive blurriness and such.  Not to mention if my next TV only has HDMI, no worries there, either.

So, that's what I have for now.  I'll probably make a more history oriented post next time within the next few days.

Everyone have a good one :)
