Nigel Mansell's dominant Red 5 Williams F1 Car is going up for Sale

The dominance of the Williams FW14B is undeniable, even if the tech may be called into question. It took Nigel Mansell to his first (and only) F1 world title in 1992, the first time a British had won it since 1976. It qualified on a pole position 7 times out of its 13 races. And despite facing off against Ayrton Senna and Michael Schumacher, it set the record of 9 Grand Prix wins in a single season.

To this day, the car remains one of the most advanced F1 cars of all time due to rule changes in 1994 that banned a lot of the technology. It came with a semi automatic gearbox (which was just starting to take over), traction control, and active load-leveling hydraulic suspension. To allow all of this to work properly with the required fail-safes, Williams ended up having to come up with their own controller and their own programming.

The hydraulic load leveling suspension was initially meant to be an all mechanical system so it was a complete transformation in controls. And in an age where you can buy a programmable microchip online for next to nothing, this might not seem like much, but back in the early 90's, doing your own controls from scratch was a major undertaking.

The load leveling suspension was more than just an active suspension. Due to the fact that ride height was actively adjustable, it could always maintain the optimal ride height of the car for aerodynamics, regardless of corner loads and suspension movement. In other words, it had active suspension and, indirectly, aerodynamics. F1 driver Riccardo Patrese described it as working like it's always in the wind tunnel.

Going beyond even the active suspension's inherent capabilities, the system allowed Williams to create a form of a Drag Reduction Systems (DRS). They noticed in testing that their active suspension car was actually slower at the end of straights by 2-3 km/h (1-2 mph) compared to their passive suspension car. They had already decided to run the active suspension car because it was working so well and it was posting quicker overall times but they wanted to gain every advantage possible so they looked further into the root cause.

They found that the passive suspension car was "stalling"; a term used in aerodynamics engineering to describe lift or downforce elements such as spoilers, wings, spoilers, etc. losing effectiveness due to their angle of attack changing. Because the passive suspension car changed its ride height in response to suspension loading, it caused the stall condition which resulted in reducing drag and allowing the passive car to reach higher speeds. To allow the active car to stall, they introduced a manual override to drop the ride height of the car, essentially creating the first DRS.

You can watch the 6 minute Williams F1 video below about what went into development which is just astonishing. It was so dominant that it allowed Nigel Mansell to secure his title a whole 5 races before the end of the season. And its designer - Adrian Newey - is still active today as Chief Technical Officer of the Red Bull Racing team, speaking volumes of his relevance.

It has been owned by a single private owner since Williams originally sold it and has been dormant until 2017.  Former F1 driver Karun Chandhok took it out for Williams' 40th anniversary celebration at Silverstone and the Renault V10 and hydraulic active suspension are reportedly working properly.

How much will it go for?

The car is being auctioned by Bonham, which is no stranger to historic F1 cars. Bonhams sold Ayrton Senna's McLaren-Ford MP4/8 last year for €4.2 million which won him the Monaco Grand Prix. That is roughly £3.8 million in today's money ($4.8 million USD). The record for the most money paid for an F1 car is £5.6 million ($7.3 million USD) for Michael Schumacher’s 2001.

That should give a ballpark for what something like this might go for. Bonham isn't providing an estimate, but there's speculation that it will go for close to £3 million ($3.9 million USD) according to Motorsport magazine. If you want a chance to bid, it will be at this year’s Goodwood Festival of Speed presented by Mastercard on 5th July.

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

Bridgestone Potenza RE-71R Track Review

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3. They work better in the rain than R comps. The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine. In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if... Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most di
