The latest Tesla to hit the streets in now close to available and has been reviewed by a number of motoroing journalists. One such review is in the Wall St Journal where Dan Neil gives it a super write up. Dan is no fool having been a contributing editor to Car & Driver. Read Review here
The S is a high performance salon car that looks like a Jaguar. The Signature model is powered by a 416 HP AC motor that produces a nice little 443 pounds-feet of torque bringing 60 MPH up in 4.4 seconds from standstill.
The four door gives plenty of room and looks great. The battery pack accounts for 30% of the vehicles total weight of 4,650 pounds.
As a company Tesla has grown from strength to strength. It starting be building an electric 2 seater base don a Lotus. It acquired the Fremont CA plant that was a GM/Toyota JV proving the company with an instant car factory. The S is defiantly a real Tesla car. With an EV the designers have the ability to try things that folks with a IC power plant just cant do. There is no engine to go under the bonnet and the need for a radiator is greatly reduced giving far more options for sexier looks.
The Tesla Model S has a choice of 3 power packs: 40, 60 and 85 KWh. These packs change the rage of the car from 160 to 230 to 300 claimed highway miles. The pack is a large matrix of Nikel Cathode Lithium Ion Panasonic batteries, more than 7,000 in total.
The car with two names and three brands has taken the highly coveted Car of the Year award at the Geneva motor show. What’s more you still cant buy one in Europe.
The Volt or Ampera is a EV with a motor that acts solely as a generator, or what the trade calls a range extender.
From the judges report:
Volt/Ampera offer is a mature product, after years of development and perfectioning by General Motors, and the first example of an electric vehicle with extended range. Others will come along this path. The concept, addressed to the fears of potential customers in front of an incipient recharging net of electricity for vehicles, implies energy generated on board, to continue the journey, once exhausted the rechargeable batteries. In the case of the Ampera/Volt, that means a 1.4 petrol engine working in semi-stationary regime. The balance between electric drive range and combustion-engine help takes in account the usually short daily displacements of the average car user. The electrical autonomy is rated at around 60 km with normal driving, then it comes the 1.4 to the rescue.
Viability of such approach, in a time when recharging possibilities on the road are limited, has been positively assessed by Jury members, who see in the Volt/Ampera a product better suited to consumers’ needs than the conventional electric car. By the way one of those preceded the Opel/Chevrolet in the CotY title. In the early phase of distribution in Europe, Opel has reckoned to have around 7,000 firm orders of this model, in spite of a high price, somewhat moderated by public subsidies.
Some stringent crash test in USA recorded heat control problems in the battery pack, and the possibility of a fire. GM has thoroughly addressed the matter and applied new solutions, with better protection of the batteries and more efficient cooling systems, so customers can be assured.
