The company is called True Electric, and they supposedly use a small and lightweight "new high performance technology" and a "unique battery management system" to convert the vehicles. OK, so that wasn't exactly detailed. We did find mention of Lithium Iron Phosphate batteries. The company's website is all in Swedish, and Google Translate isn't helping us find much more. Luckily, the Invest In Sweden Agency reprints an English press release that says that True Electric converted a Saab 9-3 to electric power and managed a 0-62 mph time of 6.5 seconds, a top speed of 180 km/h (112 mph) and a range of around 93 to 124 miles. That all sounds good, but if you can find more details, please let us know. Thanks to Jonas C. for the tip!
