2015 Tesla Model S P85D - The World's Quickest Sedan




I love sleepers. A picture of this car could be put in a dictionary next to the word "sleeper". The styling isn't aggressive. The brand, if recognized, would be recognized as an electric car maker not a performance car maker (except for the avid car enthusiast). It's a four door. It even doesn't look any different from the pedestrian Model S 60. And to top it all off, the electric motors noise (or lack thereof) won't be convincing anyone they're V8s or anything with enough power to worry about. That couldn't be further from the truth, though.

This is the fastest accelerating sedan that Motor Trend has ever tested. 0 to 60 mph arrives in just 3.1 seconds. The 1/4 mile passes in 11.6 seconds at 115.2 mph. For a full review and the rest of the stats, go to: 2015 Tesla Model S P85D First Test.




There are a couple of things I don't like about the car, though. For one, the interior. I don't know why every one is going crazy over this centre screen. Maybe I'm old fashioned but I find it huge. It looks like an afterthought; far too large for a car. Every time I look at a picture of the interior, it looks like someone took an oversized iPad and stuck it in the middle of the car. It may be a part of making a statement because of the fact that this car is supposed to change the traditional concept of a car with the electric powertrain and continuous updates. Maybe it looks better in person or maybe it looks better to more tech savvy drivers but I don't like it.




The other thing I don't like about this car is how it performs. It certainly isn't the actual performance (i.e. performance figures/capabilities) but rather how the car achieves those figures. For example, the acceleration times are blistering but 1/4 mile trap speed is very low (for the time), even by AWD standards.

For example, in an earlier Motor Trend test (Comparison: Luxury Super Sports Sedan)
the Audi RS7 did the 0 to 60 mph sprint in 3.2 seconds (only 1 tenth behind the Tesla) and ran the 1/4 mile in 11.6 seconds, exactly the same time as the Tesla. The trap speed? 120.4 mph - more than 5 mph faster despite a slower 0 to 60 mph time and an identical 1/4 mile time. The same story goes for the Mercedes CLS63 S AMG, which is even slightly slower to 60 mph and the 1/4 mile mark than the Audi, yet it crosses the traps at 122.7 mph - a whopping 7.5 mph faster than the Tesla. The Porsche is even slower than the Mercedes but still traps higher than the Tesla. The same applies to the slower Model S 60, which is comparable to a Chrysler 300C in specs, yet it has a slower 1/4 mile trap speed. What gives?

The problem (I believe) is the single speed transmission. Electric motors are always touted as being better than gasoline engines because they achieve their peak torque at 0 rpm (i.e. all torque is available from a standstill). What companies neglect to tell, though, is the fact that torque drops off after that and, like gasoline engines, electric motors have a power curve (i.e. they make their peak power at a certain motor speed/rpm and less power at speeds slower/faster than that). Gasoline-powered cars get around that problem with transmissions that have multiple speeds. The point of this is to keep the engine operating at the optimum speeds regardless of road conditions. Under light load, keep the rpms low to improve efficiency and under heavy load keep the engine at high speed to increase power.




Electric motors, though, have a much, much broader power curve and can safely rev much higher than gas engines. Moreover, electric motors can operate much more efficiently at different engine loads without changing engine speed. All of that means that you can get away with a 1 speed transmission, reducing weight, complexity and cost. The downside, is that you don't stay on the power as long compared to, say, that Audi RS7 which has an 8-speed automatic. The Audi can rev up quickly due to a low first gear to get to the peak power and as soon as the power starts to taper, you change gears and you're back on peak power and then you change gears again and so forth. The result is that you have peak power for more of the time which means higher speeds.

I don't mind the lower speeds per se, although it will change our gauge for power if the future really is electric cars (i.e. when you hear a car has 691 hp, you no longer think trap speeds above 120 mph). What I don't like is the other changes that come with it. Will electric cars ever have nearly as many speeds as gas cars? It would be a waste of money, weight and cost because they don't need it so I would say no but there's something about changing gears. It's engaging and entertaining (hence many enthusiasts lament the near extinction of manual transmissions). It's also great to go over that peak power, change gears, and do it again, again and again.

The electric car will change how we have fun with cars. The noise is gone, the traditional build up of power is gone and changing gears is gone. It will give us something in return, though. A more efficiency way for us car enthusiasts to still have fun. A way to still enjoy driving when the world would rather us not. I do love the Model S P85D and I wish I had one. If the future has as many cars like the Model S P85D when processing oil is no longer feasible as we have Mercedes AMGs, Cadillac V-series cars, BMW M-cars and Audi RS cars today, I say welcome to the future!

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

Falken Azenis RT615k+ Street and Track Review

Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax  set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load

2004 Audi TT 3.2 Quattro DSG Track Review

Before getting into this, I have to confess something... I had never driven an Audi TT before. Not until this one, anyway. But that hasn't stopped me from forming an opinion about it from the comforts of my own couch while reading and watching reviews online. After all, if you've never done that, do you even know what the point of the internet is? Now, we all interpret reviews differently. Call it confirmation bias if you will, but if you like a car, you'll read a review and look at the positives as what makes the car great and the negatives are but a few quibbles you have to live with. If you don't like a car, the positives are a few things the manufacturer got right while screwing up everything else. It's a bit harsh to put the TT in the latter category, but that's where it ended up for me... I never took the TT seriously. The problem with the TT for me isn't that it's a Golf underneath, per se. There is nothing wrong with a performance car sharing a
