The road from LOG 31 (Video)

Tuesday, January 31st, 2012

Timelapse video of 3 Elises driving back from Lotus Owners Gathering 31 (LOG 31) in Vegas back to the Bay Area through Death Valley and Sonora Pass. Route chosen by Steve M and video by John Z, I just tagged along to make up the numbers :)

It was a spectacular drive with Sonora Pass (skip to the 3:10 mark in the video to see footage) with almost no traffic and excellent asphalt quality. The pass is closed for significant portions of the year due to snow so you should call ahead before you make the journey. Full route info below:

Lotus Management on the Future of Lotus (GGLC Exclusive Interviews)

Monday, November 29th, 2010

Cross-posting the interviews I conducted for the GGLC at the LA Auto Show and originally posted on the GGLC blog:

GGLC attended the North America launch of the new Lotus range at the LA Auto Show and got a chance to speak to senior management about their plans for Lotus and the challenges in launching 5 new cars in a short span of time. Short descriptions of the interviews and their major points are below but we recommend you watch the actual videos to get a sense about the future direction of Lotus

First up we spoke to Dany Bahar, the CEO of Group Lotus about his vision for the future of the company and why they were launching so many cars in such a short timeframe. Major points that he confirmed were:

  • Not all cars will be going to aluminium skins, the Elise will remain a composite body
  • Motorsports activities will include Evora GT4, Evora GT2, IndyCar (bespoke engine and aero)
  • Simultaneous worldwide launch with an intended volume of 6-7000 cars per year

Next up was Donato Coco, Head of Lotus Design and the man behind the 5 cars on display. He spoke to us about the challenges in designing iconic cars like the Esprit as well as the goals for the design language for the Lotus range. Our favorite quite here was that the design for the new front ends has been inspired by the original Lotus Seven and if you look at the cars (especially the Elise) it does actually come through.

Finally we spoke to Wolf Zimmermann, CTO of Lotus about the challenges in rapidly developing 5 new cars. This was a great interview with reasons behind various decisions and we recommend you watch the whole video below. Significant points include:

  • Aluminium bodies are required because composite cannot provide the required quality and shapes for the new designs
  • Engines are not yet confirmed but will be decided in the next few months
  • VVA architecture and manufacturing will have to be upgraded to meet targets
  • Lotus Engineering is already involved in some of the design processes

Picked up some Lotus History

Piston from Lotus Cosworth DFV 339

The mailman just brought me this amazing piece of Lotus F1 history: a piston from the Cosworth DFV engine #339 used in the Lotus 81 Formula 1 car.

In the 70s and 80s, Team Lotus was in the habit of keeping the pistons from rebuilds to use as VIP gifts. Each engines pistons were labeled and stored but not all were presented. With reference to the teams archives, Classic Team Lotus is able to identify the detailed competition history for the engines in which the pistons ran. A great deal of polishing, then mounting on a wooden plinth, complete with presentation plaque, makes a rather special item of memorabilia.

Now while a piston from an F1 engine is amazing in itself (Ferrari charges >$600 for a 2000 piston), this particular engine has some additional history that makes it even more unique. The DFV 339 was used by not one but two F1 world Champions: Mario Andretti used it in his final season at Lotus while Nigel Mansell used it during his first two seasons in F1.

The piston comes with documentation of the engines usage and you can see that while it was used primarily in practice and testing, it was also used by Andretti in the 1980 USA GP West where he retired after a first corner accident.

Health benefits of Autocrossing

Monday, July 20th, 2009

At the last GGLC autocross Alex and I decided to try out a little experiment to see how your heart rate changes during the race. We used a Polar S720i to record his heart rate, an iPhone for video and a DL1 data logger to record G-force and speed readings. I used some simple PHP magic to sync the two data files together and used the Chasecam Dashware system to create this finished video.

You can see the speed, heart rate (BPM), longitudinal G (acceleration + braking) and lateral G in the dashboard on the top of the video. His average heart rate was in the low nineties while on the grid and rises to to 101 just before the start of the run. As the run progresses you can see it quickly rise all the way to 145 bpm by the end of the 45 second run. Just as interesting is the way his heart rate falls as soon as the run ends and drops to the low 130s just 10 seconds after the run. So now if anyone asks you why you autocross just say its for the health benefits ;-)

Unfortunately the video quality is not as perfect and the heart rate only updates every 5 seconds but all in all it was a successful test of the system. I have already ordered a Polar RS800CX (1 sec resolution) and I plan to run this same setup for the duration of the Lemons race at Buttonwillow next month. So stay tuned for the health benefits of endurance racing :-D
