The Caterham Seven CSR is the latest model from sports car manufacturer Caterham Cars. TheCSR is the most heavily modified Caterham, though it still retains the basic look of the Super Seven.The CSR has two engine options based on the same uratec block, though modifications and power output differ. The entry level engine produces !"" bhp #$%" kW&, with a "'(" mph time of ).*seconds. The upgraded engine produces !(" bhp #$+" kW&, with a "'(" mph time of ).$ secondsand a top speed of $%% mph #!+ km-h&.$/

3/9

The CSR represents the most radical redesign of the car since the introduction of the Seven in its9'year history. The CSR is the sub;ect of numerous improvements over previous models#seebelow &, though it still retains the main aesthetics of Caterhams.

Handling and brakingedit/

While slightly heavier than other Caterhams the CSR still upholds Colin Chapman, the Ferrari F%".)//%/

4n braking tests, the CSR performs well. From *" mph #$$" km-h& to a complete stop, the CSR took$" feet #) m&. The ++* Turbo, stopping from 60 mph took ++ feet #)" m&.)/ The Ferrari F%"performed well, stopping from (" mph #+* km-h& in $$+ feet #)( m&./ For comparison, an average!"$$ road car #!"$$ Chevrolet Cru?e 2S& takes $(* feet #%$ m& to completely stop from *" mph#$$" km-h& and Formula 3ne cars can stop in %( feet #$* m& from (! mph #$"" km-h&.(/*/

Low-end accelerationedit/

The CSR has e:cellent low'end acceleration because of its high power'to'weight ratio of $" bhp

#)$" kW& per ton #!(" model&. 4t can accelerate from a stop to (" mph #+* km-h& in ).$ seconds#estimated&,$/ though during trials, Car and river maga?ine could only achieve ).( seconds.9/ Thisdiscrepancy is due to the close gear ratios of the transmission and the rev limiter. The CSR that theytested could not reach (" mph #+* km-h& in first gear, and re@uired the e:tra ".% seconds to shift. Car and river e:plainsA

't/s also wic"edly uic" blowin, past 60 mph (!+ "m1

For comparison the 0orsche ++* Turbo, which has BW and weighs over twice as much as theCSR, has a power'to'weight ratio of only !(+ bhp #!"$ kW& per ton, but has a "'(" mph time of ).seconds.)/

High-speed liftedit/

The CSR, as with all Caterhams, has worse performance at higher speeds with respect to bothacceleration and handling because of the poor aerodynamics. Caterhams suffer not only from ahigh drag coefficient of ".*, but also from lift.+/ Though there have been improvements inaerodynamics, the CSR still has %" pounds of lift at $"" mph #$(" km-h&.$/$"/ These factors hinderboth high'end acceleration, top speed, and handling. With such strong wind resistance, it re@uiresmuch more power to overcome that force and increase top speed. 2ift reduces contact force on thetires, causing the car to feel =loose= and not handle as well. For comparison, the Ferrari 7n?o has alow drag coefficient of ".)! and actually creates $,*"+ lb #**% kg& of downforce at $9( mph#!++ km-h&.$$/

Cosworth engineedit/

The !(" bhp #$+" kW& Cosworth'tuned engine is heavily modified from the stock !.) litre uratec.The cylinder head, block, crankshaft, connecting rods and pistons are upgraded by Cosworth.$/Cosworth also integrates an advanced dry'sump with an e:tra internal scavenge pump to distributethe oil. While a dry'sump system re@uires more oil #more weight&, a dry'sump will keep the enginelubricated under hard cornering unlike a wet'sump system. Cosworth also radicali?es the cam shafts

and upgrades the e:haust system. this may cause to engine to run a little more =rough= at lowR0s, but it drastically increases performance. The inlet system is also replaced with an advanced,custom roller'barrel system. This increases airflow at full throttle compared to a butterfly inlet,boosting performance. The engine also has a custom chip designed by Cosworth for a furtherincrease in performance.$/

The !"" bhp #$%" kW& model uses the same uratec block, but is not as heavily modified. Theconnecting rods and pistons are not upgraded significantly, though it does have the dry'sumpsystem. The cam shafts are slightly radicali?ed, and the e:haust system is upgraded. The inletsystem is enlarged, but not replaced with the roller'barrel system. The computer chip is upgraded,but not to the e:tent the !(" model is. >enerally speaking, the !"" model is upgraded, albeit not asheavily.$/

Other featuresedit/

The CSR, has a variety of other features which enhance its performance. There are no powerbrakes or power steering, making the CSR e:tremely responsive and e:tremely agile. The clutchalso engages e:tremely high, allowing for @uick shifts while racing. 4n addition, the flywheel is verylight. This makes heel'and'toeing e:tremely @uick and easy as the engine revs up very @uickly withso little momentum.

Improvementsedit/

The springs and dampers installed inboard #push'rods, calipers not installed&.

The overall strength of the chassis is improved with the addition of new tubular steel to the frame.The weight of the car increases, but the torsional stiffness is improved by somewhere between!%D$/ and $""D.$!/ The added reinforcement was necessary in order for the CSR to support theheavy !.) litre uratec engine. The CSR is also wider than previous models, which increaseshandling ability.

The rear suspension is fully independent.

5/9

Eoth rear and front suspension were completely redesigned for the CSR. The front suspension hasdouble wishbone, fully ad;ustable, inboard springs and dampers, improving aerodynamics. The rearsuspension is also upgraded to a double wishbone, fully independent system, replacing the e iontube design.

The radiator vent on the nosecone improves aerodynamics.

Caterhams have very poor aerodynamics due to the blunt windscreen, open'wheel design, and opencockpit. Bt very high speeds, lift becomes a problem. To combat this, the CSR has several features

that reduce lift by %"D. $/ The front cycle wings are fitted closer to the tires to reduce turbulence. 4naddition, they have a small lip that angles air upward and creates a small amount of down force.

Blso, the new front suspension scheme reduces turbulence and drag formerly caused by the springand damper units. The biggest enhancement is the vent added on top of the nose cone. 3n previousCaterhams, the air from the radiator caused turbulence by knocking against the engine and otherparts on the underside. B plastic panel behind the radiator now directs air straight out through thevent, creating down force and reducing turbulence.

Review edit/

3verall, the reviews of the CSR have been positive. ost maga?ines have only reviewed the !("model. The main criticisms relate to the ease of driving and cost.$!/

Purchasing and licensingedit/In the Uedit/

The CSR is a legal production vehicle under the 4ndividual 8ehicle Bpproval schemepending a vehicle inspection. The CSR may be purchased from Caterham directlyas they are manufactured in the 56.

In the United Statesedit/

The CSR was released in the 5nited States in the summer of !""( in very limited@uantities. Bs a production vehicle, the CSR is illegal because of lack of safetyfeatures and failure to meet emissions standards. 5S law states that the engine andtransmission must be purchased separately from the chassis. Chassis may bepurchased from Superformance, Caterham
